The Millennium Aircraft



Introduction

Ever since industrial revolution surface, first wave  in Europe from 1760 to 1820 and 1840, or at the end of 18th century, or beginning 19th century, thermo-mechanical energy converter known as: External Combustion Engines (ECE) and Internal Combustion Engines (ICE) been introduced to run transportation: on land, on water, and through the air. Since then, people were dreaming to travel to far-off countries to see for themselves the scenery of the beautiful distant lands, and meet various cultures of people available on the blue planet. The dreams were blossomed in the heart of many earth citizens across the globe to ride: car, train, ship, and airplane never diminish with the passage of time. 
Two technologies have been competing ever since in market place, each perfected to fulfill   demand. They are: development of Mean Of Transportation, shorten: MOT, to carry people from home to the dream country to see the land and experience respected culture, and development of Information and Communication Technology, abbreviated: ICT. The latter also provided with   relevant gadgetry to bring the beautiful scenery of far off land with its culture back home for people to see; both are moving at rapid pace. 
The problem using MOT, is environmental pollution introduced by thermo-mechanical energy converter to the earth environment: on land, on water, and in the air due to the burning of various fuel, like: solid (coal), liquid (petroleum), and gaseous (natural gases). Such a pollution  had been around ever since the outbreak of industrial revolution, when steam engine (ECE) were used to run: factories, industries, railway networks, etc., burning solid fuels to liberate “heat” by burning coal for conversion into “mechanical energy”. Then arrived a more efficient ICE burning liquid fuel and gaseous fuel also to get “heat” for conversion into “mechanical energy”, to run transportation on land, on water, and through the air, not excluding factories, industries.
There were times when ECE were predominantly used to power steam locomotives to pull passenger and freight trains. As soon as ICE appear and been perfected, it replaces ECE to run most of land transportation, like train, automobiles, motorbikes, etc., crowding roads and streets in big cities. Similar energy converters also been used for water transports, sailing: canals, rivers, lakes, seas, and oceans; crowding them with various boats. With advent ICE, air transportation been introduced in the United States of America, and ever since the blue planet were crowded with many type aircraft, run by reciprocating-engines, jet-engines, and turbofan-engines.  
Number of thermo-mechanical energy convertor were rising quickly across the globe with time, burning: solid fuel, liquid fuel, and gaseous fuel, to get “heat” for conversion into “mechanical energy” in great demand by various transportation as well as industry. There established a stream of solid fuel, liquid fuel, and gaseous fuel from the belly of earth migrate to its surface done by man, to be burned inside various thermo-mechanical energy converter to get mechanical energy, and releasing exhaust gases to earth atmosphere around the planet polluting human living environment. The burning of fuels: solid, liquid, and gaseous, in each thermo-mechanical energy converter causing unfriendly carbon dioxide release and other toxic material polluting blue planet environment: atmosphere, land and water, already reach beyond health limit on many places on earth surface, causing people concern.
High concentration carbon dioxide along with other toxic gases cause earth air temperature over  planet surface to raise, due to radiation from the sun reflected by earth surface cannot escape to space blocked by layers of carbon dioxide and pollutants  hanging in the air. Except polluting the earth environment, the number of thermo-mechanical energy converter on service proportional with number of the mode of land transportation in drives, while the latter rising steadily with time around the globe also in correspondence with number of vehicles produced by all countries on the blue planet. That mean means the number of Internal Combustion Engine in service every day proportionally with number of the various mean transportation on: land, water, and through the air. 
On entering the 21st century, already millions of ICE of various made type and size roaming roads and streets in cities in all countries the world over. Millions of similar engine already power boats of various make type and sizes including cargo vessels and cruise liners in various to clog: rivers, lakes, seas, and ocean, creating congestion around every bays and seaports. Meanwhile millions of such engines fly aircraft of various make type and size to swarm air environment around the world’s metropolis across the globe. There are now over 1 (one) billion ICE in service on busy hours of every working days around the world. Each ICE pumps exhaust gases into the atmosphere to pollute air inhaled to human lungs. Bear in mind, the earth inhabitant is  now around 7 (seven) billion people; how swift ICE gain number one billion, since outbreak of industrial revolution in Europe.
A New Breed Aircraft
To get rid environmental pollution threatening human life on earth. So do the traffic congestion by various mean of transportation on: roads, streets, which quickly builds up in cities; also same various: boat, vessel, and liner, crowding the world’s waterways; and aircrafts variety make type, size, to swarm earth atmosphere around the globe. They are coming to our life due to the steady rising number of thermo-mechanical energy convertor to run the various transport of various make, type, size, and country around blue the planet, and a solution need be found. The latter must take into account access to the various places on earth surface, considering topographical challenge of terrain and water; also to switch mind from “think small” to “think big”. The result is the introduction of “Ultra Large Torus Rotary-wing Aircraft”, abbreviated: “ULTRA” simply write “Ultra” (Pesawat Gelang Sayap-putar Amat Besar, disingkat PGSAB); or “A New Breed Aircraft”, shorten NBA (Pesawat-terbang Biakan Baru, disingkat P2B); and later named: “The New Millennium Aircraft”, shorten NMA (Pesawat-terbang Milenium Baru, disingkat PMB).
This paper is about a new breed aircraft called ultra for application in not distant future. It is about a new breed aircraft to carry “a very heavy load” with a very large volume”. On entering the 21st century, demand for heavier air-carrier already envisaged with continuous rise of international trade. Ocean going transportations are now leaning to developing bigger cargo ships and cruise liners around the world. Bigger cargo ships are now in demand ferrying: coal, iron ore, minerals, and the like, with necessary harbors of transshipment for handling merchandise from land mode transport to ocean going vessel, and the other way round. Big  tankers are also in demand to ferry liquids like: water, palm oil, etc.; also energy: crude oil, LNG, etc. Demand for ocean going cruise liner for passengers on the rise in various part of the world entering he third millennium.
The problem to ferry merchandise with sea transportation inside container ships, is the need to have harbor for transshipment of consignment with its handling facilities. The latter is necessary to transfer consignment from land mode transportation to sea mode transportation on departure, and the other way round on arrival. Such handling facility also necessary for raw material: iron ore, coal, etc., with ocean going vessels, or liquid: fuel, palm oil, etc., ferry by tankers. The process of transshipment takes time, and become time lost in transportation. Other problem with ocean going transportation is the existence of shallow and narrow water along a variety sea line around the world, such as: straits or canals. Such routes limits the size and the drought of vessels allowed sailing, that mean limit also amount of consignment. Narrow water limit the size of a vessel allowed pass through, while shallow water limit the drought a vessel allowed sailing. Narrow water and shallow water, are the two main obstacles a vessel allowed sailing to ferry consignments between islands and continents, which spell into more time spent on sea and ocean transportation. 
With advent of millennium aircraft, afore said constraints is eliminated because it flies. Ultra or the new breed aircraft takes off from “land base” of departure of a country to other “land base” of same country or other country, to ferry merchandise inside containers, or raw materials, or liquids, even passengers. It is a kind of “Giant Aircraft Carrier” on earth, abbreviated: GAC. The latter will ferry “very heavy cargo” as well as “thousands of passengers” from one to another across the globe. On entering the third millennium, it is time to migrate moving very heavy load in very large volume, such: commodities inside containers; or raw materials, crude, etc.; or palm oil, LNG, water, etc.; by way of GAC. Large number of travelers be carried by “flying hotel and restaurants”, another variation of GAC for moving large number people through the air. Having GAC in service for cargo and passengers across the globe, obstacles encountered by ocean going ships mentioned earlier, or topographical obstacles encountered by every surface transport on land, as well as shallow and draught for water transportation, can be avoided with ease, leaving only a bow or curve in air being travelled to save time and energy. 
The new breed aircraft capable to ferry passengers remain sitting in cars, or merchandises in  truck containers, to get rid traffic congestion on roads or streets connecting metropolis with the surroundings. The new breed aircraft also capable be turn into air-ferry to move passengers insider cars, or merchandises inside truck containers, to free roads or streets connecting a metropolis with its hinterland on busy hours of working days. 
With ultra to acts for air-ferry serving metropolis across the globe, one only need to drive from home to nearby air-ferry “land base”, popularly known as “air-hub”. Also one need to drive from destination “air-hub” to his/her workplace or office, while the travel from his/her nearest “air-hub” to destination “air-hub” be borne by new breed aircraft designed and built for air-ferry. For such short haul, ultra works as an air-ferry will be able to compete with all mode of surface transportation in time and convenience. 
Such air-ferry will become the opposite of a subway services in modern metropolis of our world. With subway service, one need to go down on staircases or escalators to catch passing trains  underground, while with air-ferry people will picked up right from the nearby “air-hub”, and ferry them by air to the next “air-hub” of his/her destination.
With the introduction of new breed aircraft, planning and construction for new harbor for  transshipment of merchandise, or to ferry for passengers and vehicle from an island to another or continent and the other way round can be reviewed. This will lead to preservation of the precious natural environment inherited from nature on land and water; this does not just on surface but also depth of various water-bodies, like: canals, rivers, lakes, sea, and ocean. The atmosphere around the earth will be free from pollution, if the new aircraft powered by high capacity batteries, fuel cells, and energy coming from a nuclear fusion reaction.
The new breed aircraft can be an alternative solution to costly undertaking building roads and streets with multilayer flyovers and interchanges crisscrossing big cities and metropolis for purpose getting rid of traffic congestion; also to keep up cities with the annual population rise. With advent new breed aircraft serve as air-ferry, afore mention undertaking can be eliminated from planning stage, lead to the preservation of natural living environment on earth surface granted by mother nature conserved. 
Ultra
The idea of a new breed aircraft came to mind with the desire to get rid of traffic congestion in big cities and metropolis with “air-ferry” carrying people remain seated in their cars. Fact has shown, that the current largest fixed-wing aircraft fuselage already approaching 100 meters in length. It is not easy to construct any longer aircraft fuselage without the provision of bigger airport with longer and wider runway for take-off and landing. 
But, by transforming aircraft’s fuselage from a straight line to a circle, or from tube to torus, then migration from fixed-wing to rotary-wing, twin rotors counter-rotating in the same horizontal plane, there seems a room to rise aircraft dimension. With the implementation of magnetic levitation technology, the new breed aircraft mighty have rotors bearings be placed anywhere between center of rotor rotation and their peripheries. By conducting research on the construction of a very large dynamic flying structure along with relevant technology, “ultra”, or “a new breed aircraft”, also called “a millennium aircraft”, could soon become reality. 
The millennium aircraft is that sort of aircraft to take-off and landing vertically. It is new type flying machine having “doughnut” or “torus body” shape where rotors are installed both in the inner as well as outer circumference of aircraft’s body. Instead of a straight line connecting its cockpit with tail like the fixed-wing aircraft, ultra has circle so the two ends meet to create a ring. With such an aircraft fuselage design, two aircraft rotors to be in operation: one rotor rotates in the inner circumference of the aircraft’s fuselage, while another in the outer circumference of the fuselage. These rotors are counter-rotating, they have same center of rotation, and occupy  the same horizontal plane. The speed of each rotor must be set such a way, so the counter-rotating torques created by each rotor cancel each other to get rid aircraft’s fuselage from spinning. To maintain aircraft’s external rotor tip exceeding the speed of sound, the rotor rotation must be limited not to exceed 400 rpm. The inner rotor turns faster than the outer rotor to counter torque created by the latter.  
With multi blades and counter-rotating rotors in place, the new breed aircraft will take-off and landing vertically from “land base” built for the aircraft purpose. Another advantage having torus fuselage is the easy access to aircraft fuselage from all direction making loading or unloading of merchandise easily done, so do the passengers get onboard the aircraft or the other way round. With 360 degrees access to aircraft, stampede of passengers on entering or leaving the aircraft completely be evaded, and shorten passenger’s boarding time. Passenger can board the aircraft while driving their car for easy boarding and drive out. Similar with truck containers along with merchandise inside be ferried by ultra for easy get on board the aircraft, or leave aircraft the other way round. 
With blade’s pitch and angle with the horizontal are controllable, the new breed aircraft will easily leave the ground. Having pair ducted propellers run by electric motor on top of the aircraft’s fuselage for propulsion, the millennium aircraft will easily maneuver in flight to get to destination. The new breed aircraft is supposed to fly with medium speed of 500 km per hour.
Ultra does not need conventional airport with take-off and landing strip, but it requires “land base for take-off and landing”, known as: ultradrome. An ultradrome can be established anywhere on islands or continents close to manufacturing centers, where commodities being produced for export, and been packed into containers for consignment. Also near various mines, where raw materials like: iron, copper, aluminum, etc., been extracted from belly of earth; or: oil refinery, smelter, etc. 
Ultradrome can be built in vicinity of world’s metropolis, where a new breed aircraft serve as “sky-liner” or “air-liner” to ferry thousands of passenger on board the new breed aircraft like staying in hotels with restaurants. The sky-liner will travel from one to another city, or from one  to another country on islands or continents, for business or holidays across the various region of the blue planet, or even to make a journey around the world in several days.
The millennium aircraft may be established giant measuring hundreds of meters core diameter, or even over. It will become a very large aircraft ever, or giant air-carrier, designed and built to ferry commodities, or raw materials, such: mineral ores, crude oil, water, etc., to take the place of ocean going ships, vessels, or ships, to get marine pollution down as stipulated by the bio-environment conditions of the blue planet. The new breed aircraft also established for passengers for sky-liner or airliner much like a flying hotel with restaurants to compete with large ocean liners now in operation around the world. 
With emergence of new breed aircraft in various dimension, such as: small, medium, large, very large, and ultra large or giant, with good combination and right number across the globe to ferry commodity and passenger as requested by the call of time. The number of transportation of various mode: on land, on water, and through the air, remain making use thermo-mechanic energy converter with their new generation remain polluting living environment around the globe  will be limited to number stipulated by allowed health limit of the blue planet.
The New Breed Aircraft’s Dimensions
For the purpose of introduction, it is necessary to begin with a new breed aircraft having the Main Dimensions, shorten MD,  as proposed in Figure-I.  ****
 


 

Figure-I


There are three main dimensions of an ultra in general, that is to say:
        a – The torus core diameter (m),
        b - Diameter of aircraft’s fuselage (m), and
        c - The rotor’s blade length (m).

And for the new breed aircraft in this proposal the MD will be as follows:
        a = 1000 m,
        b = 200 m, and
        c = 150 m.

The dimension is supposed be reached in stages, beginning from: LTRA (Large Torus Rotary-wing Aircraft) the smallest in the family, to be followed with MLTRA (Medium Large Torus Rotary-wing Aircraft) the lower medium, then by VLTRA (Very Large Torus Rotary-wing Aircraft)  the upper medium, and ended with ULTRA (Ultra Large Torus Rotary-wing Aircraft) the largest of all. 

For purpose research and development, a smaller new breed aircraft’s sizes for models is introduced to get to know the new breed aircraft behavior, etc., in flight, such as:
        a.       0.5 % of Ultra’s MD for the testing of mechanical bearing,
        b.      2 % of ultra’s MD for the testing of magnetic bearing,
        c.       etc.

The new breed aircraft fuselage been divided horizontally in: upper and lower compartment. Upper compartment allocated for the prime source of energy, such: aircraft fuel, or liquid hydrogen, or LNG, or batteries, or nuclear fuel. Also all kind aircraft’s power equipment, like: thermo-mechanical-electric convertors, electric power distribution, control board, protection, as well as monitoring system. The aircraft’s rotors along with mechanical or magnetic levitation bearings, linear motors to turn the aircraft rotors, etc., are also located in the upper compartment. 

The new breed aircraft’s upper compartment also reserved for the new breed aircraft’s cockpit along with the flight control and navigation system. The Radar System for Collide-Avoidance (RSCA) in flight, as well as Aircraft’s Crash-Avoidance System (ACAS) been placed in the upper compartment. 
The lower compartment been reserved for payload, such as: merchandise, raw material such: ores, coal, etc.; or liquid: crude oils, water, etc.; or gaseous: LNG, etc. For a sky liner the lower compartment reserved for passenger cabins. For a combine payload, the lower compartment being divided into commodity zones and passenger areas. 

The New Breed Aircraft’s Technology
There are ways a thing can fly in the air. Nature introduced birds with a pair flapping-wings, while bees making use a pair vibrating-wings. Man introduced fixed-wings aircraft with propulsion and rotary-wings helicopters. This give birth the four known principle of aircraft’s   dynamic flying with wings: flapping-wings, vibrating-wings, fixed-wings, and rotary-wings

Ultra belong to rotary-wings aircraft having lift generated like every aircraft do where airfoil is made to advance against still air. Lift produced depends on airfoil design, angle of attack, and the relative speed of advance. In a rotary-wings aircraft including ultra, the aircraft does not need to move to create lift, but the rotor blades need to advance against still air. 

Like most helicopter, rotary-wings aircraft has one rotor on top of aircraft's fuselage been accompanied with counter-torque propeller at tail that work horizontally to enable the aircraft leaves the ground. Other rotary-wings aircraft provided with two rotors on top of the aircraft’s fuselage: one having single shaft with double rotors, one rotor on top of the other, counter-rotating without counter-torque propeller at tail. Another a double shafts in tandem on top of the aircraft’s fuselage, lay side by side on the same horizontal plane, or at a different horizontal plane; each rotor may turn in the same rotor rotation, or counter rotating, without counter-torque propeller at tail. 

Ultra belongs to rotary-wings aircraft with single axis of rotation, called: Center of Rotors Rotation abbreviated: CRR, or aircraft’s center point. It is equipped with two rotors, one lay inside the torus called: “inner rotor”, while the other lay outside the torus called: “outer rotor”. Both rotors occupy same horizontal plane, having counter-rotating rotors to get rid of aircraft’s body from spin. A CRR is just a virtual point, because one cannot establish any mechanical link between aircraft’s fuselage and rotors to transfer the aircraft’s weight at that point, as one can find in a conventional helicopters. 

If one walks away from the center point or CRR as the rotor turning, he/she will inscribe a virtual circle. The further one goes, the larger the diameter of a circle will be. When one reaches the inner torus diameter, it will become the Inner Torus Radius, abbreviated: ITR, of new breed aircraft’s fuselage. If one goes any further, he/she will reach the outer torus diameter will become the Outer Torus Radius, abbreviated: OTR, of the aircraft. Both ITR and OTR are the two important positions of the aircraft’s fuselage, because only at those points the new breed aircraft’s weight is transfer into rotors by mechanical or other means. 

To establish mechanical or other mean of contact between the new breed aircraft’s fuselage with  its rotors, a combination of “ring and lining”, or pair of “ring and lining” necessary: one be installed on ITR, while another on OTR of the new breed aircraft, as shown in Figure-II. These rings must be made out of very hard steel for strength. To enhance ring’s resistance against torque generated by rotor blades on take-off as well as flying to destination, each ring is built with a right diameter and the relevant thickness to allow every ring hollow out.  

 

Figure-II


A certain blades number been attached to inner rotor ring horizontally pointing toward the new breed aircraft CRR. Same number blades also being attached to outer rotor ring horizontally, but pointing against CRR. Every aircraft’s rotor blade, either attached to inner rotor ring as well as outer rotor ring, has two degrees of freedom: one along blade's length axis for pitching, and with respect horizontal plane for rolling. 

As aircraft rotors turn, each blade will generate a lift. Aircraft's inner rotor lift will be the sum of all lifts generated by blades connected to inner ring. Similarly, outer rotor lift will be the sum of lifts generated by blades connected to outer ring. The new breed aircraft's lift will be the sum of lifts generated by inner and outer rotor ring, to constitute a new breed aircraft’s or ultra’s lift for take-off  from ground. 

The inner rotor turns in one direction, while the outer rotor turns in the opposite direction to create pair new breed aircraft counter-rotating rotors. The speed of each rotor rotation must be set in such a way to allow counter-acting torque generated by each rotor equalizes each other perfectly. By maintaining the counter-acting torques balance each other in real time all the way during flight, the new breed aircraft’s fuselage will not spin to any direction. 

New Breed Aircraft Transfer Technology 
There are some technology a new breed aircraft’s may transfer its fuselage weight to the rotors, that is to say: mechanical contact transfer, and magnetic contactless transfer. In either by way, a ring lining pair are necessary been placed right in the inner torus as well as outer torus of the new breed aircraft. With contact transfer, the space between ring and its linings being filled with lubricant to get rid mechanical friction causing material to erode and energy loss, which give birth: The Liquid Mechanic Transfer Technology been abbreviated LMTT. With magnetic contactless transfer, the space between ring and its lining been filled with magnetic field, and give birth:  The Magnetic Field Transfer Technology, been abbreviated: MFTT. That is why there are two ways available for new breed aircraft to transfer its fuselage to rotors the following:  

a. The Liquid Mechanic Transfer Technology


Figure-III



Figure-III gives the illustration of a “ring and lining” pair of LMTT for the new breed aircraft to allow the aircraft’s weight being transferred to its rotors, also known: “mechanical bearing” having liquid lubrication. As one can see from the drawing, there have to be a “space” between the ring and its lining, in order lubricant can get in to overcome mechanical friction between the relative fast moving parts with the stationary, as well as the loss of energy. 

There exist two lubricant layers separating every ring from its lining: the upper lubricant layer and lower lubricant layer. The lubrication layers, except to separate the fast moving part from the stationary to evade physical contact between them; also acts as a medium weight transfer between the new breed aircraft's fuselage weight with its rotors, making use the new breed’s aircraft’s inner lining and outer lining to imitate mechanical bearings. 

To enhance the role of lubrication separate the fast moving part from the stationary to evade friction and loss of energy, a lubrication pump be introduced to raise lubrication pressure. The latter leads to a complicated lubrication system along with the required seals to get rid lubricant leakage. This is the disadvantage of using LMTT for ultra, because almost impossible to maintain high pressure liquid in a ring and lining pair, the one shown in Figure-III without lubrication leakage. The high lubrication pressure put into an open system will inevitably incur  the loss of large quantity liquid. 

Other disadvantage of LMTT by way a pair of ring and lining along with lubricant in between is to put the aircraft’s rotors into motion. Mechanical power use to turn the aircraft’s rotors must come from two independent prime movers, been transferred with help of gears and shaft systems directly delivered to every ring. 

The challenge of LMTT for new breed aircraft is how effective mechanical power coming from two independent prime movers to turn counter rotating rotors lay in a plane may be transferred, with the establishment efficient high pressure lubrication system in spaces between every ring and its lining. 

 b. The Magnetic Field Transfer Technology



  

Figure-IV



Figure-IV introduced another “ring and lining” pair for the new breed aircraft to transferring its weight from fuselage to rotors. To get rid of the problem raised in LMTT, a magnetic field is called for, to get MFTT, also known: “magnetic bearing”. Now the rotor rings must levitate inside their linings to avoid physical contact with the latter to get a real magnetic bearing. In latter technology, magnetic field will “replace” the lubricant to transfer the new breed aircraft’s weight from fuselage to rotors. A magnetic levitation ring and lining pair is introduced, as shown in the drawing. There are several category magnetic levitation transfer technologies undergoing research in some developed countries for application in transportation, namely:
     1. Electro-Magnetic Suspension (EMS)
     2. Electro-Dynamic Suspension (EDS)
     3. Superconducting Magnetic Levitation (SML)

With magnetic field in the spaces between rings and their linings, the new breed aircraft is able to avoid unwanted physical contact between rings and their linings, or fast moving parts with the stationary parts, to get rid mechanical friction causing material erosion and the loss of energy. With the implementation magnetic levitation technology, the new breed aircraft’s weight be transferred to rotors, first: from linings to the magnetic field then by the latter to rings fixed to aircraft’s rotors. The levitation of each ring in its lining been monitored in real time controlled in precise by electronic control system. The adjustment of each ring to its lining be carried out   varying each magnetic field strength involved in combine action. 

The Magnetic Field Transfer Technology 
To switch a new breed aircraft’s weight transfer from LMTT to MFTT, means to have a aircraft’s weight transfer make over from lubricant to magnetic field. With LMTT, there are two liquid layer involve transferring the aircraft’s weight to its rotors: the upper liquid layer and the lower liquid layer of lubrication. 

This lubrication layers work as “double bearing” for the new breed aircraft: “the upper liquid bearing” and “the lower liquid bearing”; both hand in hand transfer the aircraft’s weight from fuselage to rotors. With the new breed aircraft’s weight transfer change from “lubrication” to “magnetic field”, similar approach also been followed with the introduction: “upper magnetic bearing” and “lower magnetic bearing”. Both bearings will dynamically levitate the new breed aircraft rings in their linings during take-off as well as flight to destination. There will be magnetic field combine actions happen between each ring with its lining in every rotor alongside it to occur, controlled by very quick response electronic system, during aircraft’s weight transfer from fuselage to rotors during take-off and flight to destination, as follows:
  1. EMS and EDS Combine System
  2. Double SML Combine System
  3. The Other Combine System

1. The EMS and EDS Combine System
 The idea introduced by LMTT with a double bearing approach to aircraft’s weight transfer has the advantage that can also been applied to MFTT for use in new breed aircraft. This point of view leads to the development of pairs of “electro-magnetic bearing”, known as “magnetic levitation lining” to transfer the new breed aircraft's weight to rotors. A proposal EDS and EMS for a combine system for weight transfer been illustrated in Figure-V. 

A laboratory must be set to conducted research to develop a magnetic levitation lining of that sort from scratch to find out: a right design, component arrangement, dimension, field strength, electronic control, and the testing for application to a new breed aircraft. With EDS and EMS Combine Systems, the magnetic field of every constituent must work in unison along a program to levitate every ring in the lining under the continuous supervision and control of quick response electronic system. 




Figure-Va


The EMS system to work as maglev's lower bearings pulls the inner and outer rings down, while EDS system acts as maglev's upper bearings push the inner and outer rings together also down. The push-pull action of Combine EDS and EMS System will keep the high speeding inner and outer rings to levitate inside “maglev lining”. This way ultra’s rotors rings can get rid the physical contact with their linings to avoid the friction and loss of energy. 

The new breed aircraft’s working regime are: take-off, flying, landing, and parking has many thing to do with the combine action of EMS and EDS System get rid the physical contact between rings and their linings in the course of time to avoid mechanical friction and loss of energy. The design of magnetic levitation lining has to involve those aircraft’s necessary working regimes.

Only electric power is necessary to maintain the magnetic field strength in combine EMS and EDS Systems for each ring to levitate inside its lining; much like one that been achieved by the German or Japanese magnetic levitation train. Loss of electricity means the  loss of magnetic field, that lead to the fall of every ring onto its  lining causing the creation mechanical friction along with the energy loss. 

Figure-Vb


2. The Double SML Combine System 
Other alternative for the new breed aircraft to get its fuselage weight been transferred to rotors by magnetic bearing pair, is the implementation a Double SML Combine System as illustrated in Figure-VI.



Figure-VI


The difference between a Double SML Combine System with a Combine EMS and EDS System previously described, is the application superconductors, from materials like: Yttrium Barium Copper Oxide (YBa2Cu3O7-x), been cooled in liquid nitrogen to its critical temperature of 92 K (-181 ºC).  
In a double SML system, superconductor work as upper maglev bearing to push the inner and outer rings down, while the second SML act as lower maglev bearing to pull the inner and outer rings also down. The advantage implementation of Double SML Combine System differ from the an EDS and EMS Combine Systems is the fact, once the system been notified on the “clearance” each ring has to make with its lining, a Double SML Combine System will automatically do the push-pull action in a memorized clearance previously introduced to the  magnetic bearing system.  
With implementation of Double SML Combine System, the armatures must be cooled down to the transition temperature to activate its superconducting property.  

3. The Other Combine System
Further research must being carried out to get magnetic levitation bearing improved quality, either for the upper bearing as ell as the lower bearing, with the implementation of new materials as well as more up to date system design. The aim is to seek for a simple and reliable magnetic levitation bearings technology of easy maintenance, consume less electric power, as well as long service life.

The New Breed Aircraft Propulsion 
In order a new breed aircraft can fly to its destination propulsion is necessary. The new breed aircraft will be equipped will electric propulsion, because it has on board source of electric power, that is to say: thermo-mechanical-electric converters with conventional or nuclear fuel, or high capacity batteries, or fuel cells with liquid hydrogen, or others. 

Ultra been proposed to have two propellers each housed in a duct driven by electric motor. These motors are diametrically position on top of aircraft’s fuselage. The combine action of these propellers will determine total trust generated in the course of aircraft’s flight as well as speed. The aircraft flight direction be changed by way aircraft’s counter-torque unbalance of the   rotors, or trust discrepancy created by new breed aircraft’s propulsion. Figure-VII shows the position where the new breed aircraft’s propulsion is proposed been installed.  




Figure-VII


The New Breed Aircraft Energy Demand      
Due new breed aircraft dimension is enormous in size, capable carrying very heavy load or very large volume, like: merchandise in very large amount, or raw materials, or passengers in very large number; the new aircraft will be extraordinarily heavy requires very large power for take-off and fly to its destination.

Conventional fuel is not fit for the new breed aircraft or ultra as the prime source of energy, because chemical reaction arises from burning: solid, liquid, or gaseous fuel, release low energy content, few eV per unit mass. Such energy sources takes up high percentage aircraft weight as well as volume for the storage of fuel and requires frequent refueling. Other disadvantage of conventional fuels, except hydrogen fuel, they pollute the human living environment with carbon dioxides and other toxic gases. Conventional fuel used only for new breed aircraft smaller dimension such as aircraft’s models for gathering in flight experimental information, and other purpose assignments.

On the other hand, nuclear fuels contain ten million times more usable energy per unit mass is suitable as the prime source of energy without the need of fuel storage inside the new breed aircraft, and a very long time for refueling. A nuclear fission reaction releases about two hundred million eV (200 MeV) energy per unit mass for every event. 

A nuclear fission reaction releases vast amount kinetic energy of nuclear fragments along with electromagnetic radiation in the form gamma rays in the reactor. These energies later converted into heat by way of particles collide with atoms and gamma rays radiation of materials that make up reactor and its working fluid mostly water or occasionally heavy water. 

Nuclear fuel is used as the prime source of energy for the new breed aircraft, of the from nuclear fission reaction or nuclear fusion reaction, because both liberate very high energy content per unit mass, without fuel storage inside the new breed aircraft  with refueling period of say: once every 5 to 10 years. 

A new breed aircraft or ultra is a fully electric powered flying machine, because it consumes mainly electrical energy. Electric power is required for the levitation aircraft’s rings in their magnetic linings, run linear motors to turn the aircraft’s rotors for the creation of lift, run aircraft propulsion for flight to destination, lighting, aircraft’s control and navigation, and so forth. Also to run the monitoring system, the telecommunication system, avionic, Radar System for Collide-Avoidance (RSCA) in flight, and the real time Aircraft’s Crash-Avoidance System (ACAS), etc. 

Heat generated inside nuclear reactor converted into electricity first by way of Thermo-Mechanical-Electric Converter, or TMEC for short. A TMEC unit of a new breed aircraft is a “power block comprising: nuclear reactor for the generation of heat, steam or gas generator for conversion water into steam or gas into high pressure, turbine to convert potential energy of steam or gas inside a vessel into mechanical power, a high voltage generator to get electrical energy. 

The number of power block installed in the upper compartment on board the new breed aircraft could be 3 or 4 units, and are equally spaced. Such an arrangement is necessary to get load distribution inside the new breed aircraft, to allow the latter be stable in flight as can be seen in Figure-VII.  



Figure-VIII


With more block number on board, means the smaller each unit by power, weight, and volume become. Power generated by all block to equal total power required by new breed aircraft for take-off at its maximum weight in MW with some percentage of overhead power reserve. The power of each block is the total power required divided by number of power block to be installed on board the aircraft. 

The Thermo-Electric Converter
There are two ways heat been liberated in a nuclear reactor be converted into electricity  on board the new breed aircraft, that is to say: Thermonuclear-Mechanical-Electric Convertor, shorten TnMEC, and Thermonuclear-Electric Convertor, shorten TnEC. 

a. The TnMEC 
A Thermo-Mechanical-Electric Converter (TMEC) is similar to a standard coal fired electric power plant aggregate to consists of: boiler for the generating high pressure steam, turbine for conversion high pressure steam into mechanical energy, and high voltage generator for the  generation of electrical energy. For the case of TnMEC aggregate, the boiler be replaced by a nuclear reactor, either with fission or fusion reaction. 

At present, the nuclear fission reactor as heat generator to become part of power block may be one of the following: Pressure Water Reactor (PWR), or Boiling Water Reactor (BWR), or Advance Gas Cooled Reactor (AGCR), or similar others. While for the nuclear fusion reactor to become part of power block may be tokamak with magnetic confinement technology to keep   ultra high temperature plasma away from the reactor’s chamber. 

The efficiency of a super critical pressure coal fired power plants at 300 bar steam pressure and temperature of 600 °C, is in the range of 42% to 48 %. In a nuclear power plants having Rankine thermodynamic cycle on the steam turbine side and steam temperatures at saturated conditions, the thermal cycle efficiency is lower only about 38 %. 

b. The TnEC    
The efficiency of a static thermoelectric power converter having no moving part remains very low; also same with electric power it can generate in kW. This type converter is still undergoing development and research to get to the required capacity of a power plant. This is the reason why TnEC as a power plant will not come into existence in the near future.

The TnMEC for the New Breed Aircraft
There are two prime source of energy for new breed aircraft from the nuclear reaction for conversion into electricity to satisfy the aircraft’s thirst of power: the nuclear fission reaction and the nuclear fusion reaction. Every reaction will release enormous amount of heat that been revealed by Einstein’s famous energy-mass formula: E = mc2. The thermal energy liberated or heat then be converted into electrical energy in each TnMC block on board the aircraft. 

1. The Nuclear Fission Reaction
A fission reaction is the split of massive nucleus into subatomic particles along with the release of photons in the form gamma rays, free neutrons, and others. A typical fission reaction involving 235U and neutron, is as the following:

FORMULA I

Nuclear fission reaction been used in many countries since the 2nd Word War for power plants to generate electricity. A lot of information with experiences been gathered ever since been documented in scientific books and journals. 

Fission reactor been applied already as the prime energy source for marine propulsion in   aircraft carrier for many years without refueling and submarine capable submerging underwater  months without the need to surface at all. 

One disadvantage of nuclear fission reactor for use as prime energy source of a new breed aircraft, is radioactivity fall out it releases to living environment in the form of alpha and gamma rays aside from the atomic fragments and energy. 

With advent of the new generation nuclear fission reactor, lesser radioactive fall-outs been released to the environment. With the implementation of new generation fission reactor, the new breed aircraft will get the prime source energy from nuclear reactor for its maiden flight. 

Figure IXa shows a TnMEC block as the prime source of electrical energy coming from a nuclear fission reactor known as PWR. 



Figure-IXa 


2. The Nuclear Fusion Reaction
A fusion reaction is a combination of two or more light nuclei atomic number to form new element of higher atomic number (more protons inside the nucleus). With current technology, the readily feasible reaction is between nuclei of two heavy isotopes of hydrogen deuterium (D) and tritium (T); they are both the isotopes of hydrogen. Each D-T fusion reaction event will release energy, as the following:

FORMULA II

Currently, two different experimental approaches been studied, that is to say: the fusion reaction with magnetic confinement and the fusion reaction having inertial confinement. The most effective magnetic configuration is a magnetic confinement in a torus shaped much like thin doughnut, in which the magnetic field been curved around to create a closed loop.  

There are some type torus confinement systems, and most important of all the tokamak which mean "torus chamber" in Russian. Today, many countries take part in the fusion reaction research led by the association of: European Union, USA, Russia and Japan, with vigorous programs including China, Brazil, Canada, and Korea. 

The Joint European Torus (JET) is the largest tokamak now operating in the world today. Up to 16 MW fusion power for one second had been achieved in D-T plasmas making use the device, s well as experiments conducted to study the different heating schemes and other techniques.

Collaboration was established under the auspices of IAEA, between 1988 and 1990, the initial designs were drawn up for an International Thermonuclear Experimental Reactor (ITER) with the aim to prove that fusion reaction could produce useful energy. 

In 1998, the ITER Council approved the first comprehensive design of a fusion reactor based on well-established physics, and technology in the building ITER-Fusion Energy Advanced Tokamak (ITER-FEAT), but still achieve the targets of a self-sustaining reaction and a net of energy gain.

After 15 years of deliberation, the international scientific community has chosen Cadarache in the southern France, as site for the international ITER project, with which scientists hope to tap the energy from a thermonuclear fusion source. 

Note: Condense from “The Encyclopedia of Earth”.

The implementation of nuclear fissile fuels or nuclear fusion fuels as prime energy source for the new breed aircraft, also mean the installation of heavy machinery of large size, such as: nuclear fission reactor, or nuclear fusion reactor, TMEC units, electric power distribution, accessories, etc. For a new breed aircraft, heavy machinery of large size pose little problem for the installation because the space is available.      
   
The amount of energy liberated by a nuclear fusion reaction is three to four times greater than energy released by a nuclear fission reaction. This is because the mass transformed into energy in fusion reaction is much larger than in fission reaction. 

Figure IXb illustrates a TnMEC unit with the prime energy source coming from a nuclear fusion reactor known as tokamak. 



Figure-IXb 


The New Breed Aircraft’s Power System
The power generated by TnMEC blocks onboard the aircraft are sent to the main switchboard as shown in Figure-X. 


Figure-X


As can be found from the given drawing, there are three generators supplying electric power into a switchboard on board the new breed aircraft. The generated power then fed into outgoing feeders the following: 
                   1. 6 (six) feeders for the inner ring magnetic levitation bearing
                   2. 6 (six) feeders for the outer ring magnetic levitation bearing
                   3. 6 (six) feeders for the inner ring linear motors
                   4. 6 (six) feeders for the outer ring linear motors
                   5. 2 (two) feeders for ducted motor electric propulsions
                   6. 6 (six) feeders for the reactor and boiler pumps
                   7. 2 (two) feeders for the Radar System in flight Collide-Avoidance (RSCA), and  
                       Aircraft’s Crash-Avoidance System (ACAS) real time monitoring
                   8. 1 (one) feeder for telecommunication, avionic, navigation, control and monitoring
                       in real time, and so on
                   9. 1 (one) feeder for aircraft’s air condition and cabin pressurization system, lighting,
                       etc.
                10. 1 (one) feeder for aircraft’s emergency power supply system.

The Aircraft’s Impact on Ecosystem
The impact a new breed aircraft will give on human living environment depends on the prime source of energy been used. If conventional fuel burned except hydrogen, carbon dioxides will be released to the surrounding air along with variety toxic gases. 

If the new breed aircraft uses nuclear fuels, radioactive fall-outs been released to human environment much depends on the generation of nuclear fission reaction technology put on board the aircraft generating electricity. Newer generation of nuclear fission reactor technology releases less radioactive fall-out to human living environment. 

According to the report released, a thermonuclear fusion reactor is much cleaner than a nuclear fission reactor for the generation of electric power in term polluting the biological surroundings.
Thermonuclear fusion reactor will then be a better candidate for the prime source of energy for future new breed aircraft known as ultra.
