NASA's X-57 "Maxwell" all-electric aircraft can be the pathfinder for next-generation aircraft.

The next-generation technology will turn the dream of a "one-hour world" possible also in physical form. The next-generation hypersonic VTOL systems can be more revolutionary than some SR-72 or some other systems alone. 

If we think about modern technology, that thing makes it possible to create an aircraft with the capacity for hypersonic flight, low-speed flight, and vertical take-off and landing. That thing is quite easy to solve. There is needed only three series of engines. 

Regular jet engines, ramjet- and scramjet engines can be used in stages. At first, the regular turbojet will accelerate the speed to Mach 1,5, where the ramjet can start. Then the ramjet will accelerate the aircraft to Mach 6-7, where the scramjet can begin its operation.  And the VTOL system can use blowers that make the aircraft operate silently above the city.

The systems developed for "flying cars" can use for larger-scale aviation systems development.

The blowers used in some experimental "flying cars" can have two engine series for flying, in that case, the system uses blowers for lift-off and low-speed flight. And then it can turn to use micro-jet engines. 

Blower-based low-noise systems are giving those "every man's" flying machines a top speed of 200 kilometers per hour. Those little systems' speed can easily increase by using two engine series to 600 kilometers per hour. The flying car will rise into the air by using the blower system and then turn to increase its speed by using miniature turbo jets.

The speed of blower-operating micro-aircraft will remain at about 200 kilometers per hour. But that kind of system can also equip with small jet engines used in cruise missiles. So, when the pilot wants to turn to a travel flight there is possible to change the engines. When the distance to the city area is high enough pilots can turn to use those turbo jets. 

If the regular aircraft has this kind of blower system, it can lift off by using blowers. The aircraft can also cruise above the city by using blowers. And then outside the city area, it can start its jet engines.

So, there are tested things like pulling propellers for creating the airflow that speed is fast enough that ramjet engines can start their operation. Those systems are basing fast-rotating cavitation propellers that make a vacuum or cavitation bubble behind the ramjet engine. And those propellers can pull the airflow so fast that hydrogen starts to burn in the ramjet engine. 

Another solution could be the plasma-jet engine. In those systems, the engine creates plasma by using an electric arc. And then magnets will drive that plasma behind the engine.

The main problem with SR-71 was that aircraft couldn't operate at low speeds. The problem would be solved by connecting the regular jet engines to the SR-71-style aircraft that can operate at incredible speeds. 

In air inlets of regular turbojets could be an iris that closes air flow to turbines when the aircraft's speed is too high. And if the aircraft would operate by using ramjet or scramjet systems the rapid air turbine could give electricity for the avionics of that aircraft.

The aviation of future


The aviation of future


The primary tool in the military and civil aviation is highly sophisticated artificial intelligence. The thing, that makes artificial intelligence so effective tool is that it can handle the robots, what are fixing problems and damages very sharply, but it can control the great entirety.

If we are thinking the artificial intelligence, that thing can make new aircraft more effective, even if there is old-looking aircraft. But as I have written before the human-shaped robot can also be used as the pilot of the aircraft, and that thing can turn every aircraft in the world to the drone. And it can communicate with controllers by using satellite communication, which could be internal or it can connect itself to the communication system of aircraft.

Below this text is the BAEs promotion video, what the aviation of tomorrow would look like. That kind of system might provide new kinds of advantages and opportunities, what is ever seen in aviation before. The nanotechnology will give the aircraft change to fix its damages, and the highly sophisticated artificial intelligence can make that kind of process without pilot even notices that there is some kind of damages. There could be so-called nano-latex, what is formed small machines, which could fix the holes autonomously.

Those mechanic spiders can walk inside the body of aircraft, and if there would be holes in the body, some of those robots would go to make the supporting structure in that hole, and rest of them would release the carbon fiber to that hole, and because of that the aircraft can continue its operation even if there are damages in structures. In some other, more conventional scenarios inside the body of aircraft would installed robot arms, which is equipped with 3D prInters, which can fix holes.

Those 3D printers can manufacture spare parts to vehicles and equipment, and in theory, they can manufacture entire cars and aircraft in operational areas, which makes those systems very effective for supporting actions near the operational area. They can be used to make almost every particle, which is needed for successful operations.

The modular aircraft can dock other aircraft wIth it Is also a really interesting idea. If we are thinking about the structure, what can connect and then separate parts of it for independently operated vehicles, we can think the opportunity to create aircraft concept, what can be used to every mission. If the pieces are together, that thing can use as the heavy strategic bomber.

But if the sub-parts of the plane would be released, they can act as well as the fighters and assault systems, and the thing is that this kind of system also allows replacing part of the aircraft during the flight. So if we are thinking about the use of that system in the military actions, those aircraft can carry heavyweight bombs to some area, and after bombs are dropped, those parts can be released and turn to very effective fighters. Also, those modular aircraft would be stored in smaller hangars, which will cover the existence of big bombers. This kind of new advantages might be more revolutionary than we ever thought.

Aviation and ICT-sector

Aviation and ICT-sector

The carbon-dioxide releases of ICT-sector are bigger than aviation, and that is not a surprising thing. The NSA headquarters has been the largest energy user in the State of Maryland. The monstrous server rooms need always a very large-scale electric supply. And the number of those server rooms is increasing all the time. The reason is that mobile devices transfer the calculating capacity to the servers, which means that those systems need more and more power.

The high-power computers and servers need more and more electricity and the mobile systems, what is communicating with servers needs more electricity for communication processes. And if we would use light and non-powerful processors in the mobile systems, we would transfer the calculations to the servers, and that means that we would need more and more powerful server technology.

The reason why this thing has happened is that the remote use of computers and digital meetings will be a cheaper choice for companies, than some business trips. The manager of the big company might have even tens of meetings per day, and that means if those meetings would happen by using physical traveling, the price of those meetings would be very high.

But there has been one reason, why the big companies have turned to use virtual meetings. The reason is the security checks and if the laptop computer must be left to the airport would the result be devastating. Every contracts and paper would leave behind that person, and that is the reason, why there have been created the solutions like web-based documentation software and writing tools, that the person must not carry them across the border.

Also, the usage of Web-based solutions is easier to control than some local tools. That means that if some persons use very expensive software, and then leaves the company, the user rights of those applications can be denied immediately. In this case, the software would not able to use anymore, even if the laptop disappears in some airfield.

A way to make things invisible in radar and also make new kind of radioactive protection.

A way to make things invisible in radar and also make new kind of radioactive protection.

Magnets can turn the radioactive radiation and radio waves away from the target and revolutionize STEALTH and radioactive protection. There is a connection between STEALTH- technology and technology, what is created to protect people and targets against radioactive radiation by turning those particles away from their route by using magnets. The magnets can also turn away the radio waves. The thing is that the system would work in the cathode ray tube makes it in theory possible to create also the magnet-based system, what turns radio waves and radioactive radiation away from the route.

STEALTH means the system, what turns the electromagnetic radiation away from the surface, and the thing is that this same technology can be used to turn away the radioactive radiation from the surfaces. One of the most interesting versions of the systems, what have been created for protecting people against the radioactive radiation is simply use a powerful magnet, what will suck the helium ions to it, and that thing would turn the alpha ions away from the protected areas.

The thing that the system would have two magnets, what have the opposite polarities would be used to turn the beta radiation away from the route. If the magnets would be at the opposite sides of the vehicle, they could turn the nucleic radiation away from the track. And the thing, what would make that system more effective is to use two separated magnets to push the ions away from the magnet, what has the right polarity.

An idea is that in this case, the system uses the pulling and pushing effects of the magnets, and that effect has influence in the ionized particles. In the world of the military, there have been plans to use the drones, which have extremely powerful magnets to pull the radio waves away from the aircraft or warships. And the idea to turn the route of the radio waves by using the magnets is taken from the old time television, where the image was created by using the electron ray, what would move right and left by using magnets, and some physicians have thought that the magnets can also turn the radio waves in the air.

The thing is that the powerful electromagnets would turn the route of the radio waves is possible, but the real thing is that there could need very powerful magnets for turning the route of radio waves would limit the use of that system. In theory, this kind of system can be actually the drone, what flies near the flight group, and if the power of those magnets will be powerful enough, the route of the radio waves would turn away from the flight group.

Lightweight electric aircraft could also be multi-use models

Lightweight electric aircraft could also be multi-use models


Electric engines will give the aircraft the ability to fly silently and ecologically if the electricity is created by using pure energy, like geothermal or other clean sources. The thing, what is used in those aircraft allowed to fly them by using batteries, and recharging of those things would happen just connecting the aircraft to the power plug, and in fact, the normal 230 V system is suitable for charging the batteries.

When we are thinking about the electric motors, those systems can be used also as the generators. That means that the loading the electric system can happen by pulling the aircraft through the air. In fact, those electric motors can be used in the VTOL (Vertical Take-Off and Landing)  jet fighters for rising the aircraft to airborne and then the jet engines would be started. But the small size aircraft can also fly in very high altitude, and when the batteries are ending the pilot can turn the electric system to "load" position, and the aircraft would flight like a wagtail.

When the flight heads down the aircraft will load the batteries and then the aircraft will climb to the high-altitudes it will use the electric motor. Maybe in the future, those aircraft will be equipped with lidar system, which helps them to find the rising air flows, which will help them to take more altitude and save energy.  And if the system is used the fuel cells would the operating those small aircraft will become more sophisticated.

Hydrogen fuel cells can bring even small aircraft able to fly extremely high altitude, and when we are thinking about this thing as the point of view of the number of passengers In some visions those aircraft can be used as the miniaturized shuttle, and the propellers would operate as RAT, what would load the batteries, when the shuttle would land in the atmosphere after the ballistic jump, where it can use the small rocket, or it can be launched from the high-altitude aircraft. This would be the new kind of version of X-37B, which can also have propellers to operate in the operational area.

This means that those shuttles have the ability to operate freely in the low altitudes by using electric power systems. In fact, the electric aircraft can be carried five-member rescue team to the areas, what are difficult to reach. And they can have sophisticated sensors, which would help to find the victims. But those silent and quite fast VTOL systems can be used also carry five men SWAT-unit to the roof, or they can operate in the reconnaissance and light attack duties in the military.

They can be equipped with machine guns, surveillance, and lightweight electronic intelligence kits, and Dragon-type lightweight anti-tank missiles, which are effective at least against armored personnel carriers and support units like fuel cargo systems. If those aircraft would slip near the enemy airfield they can use those weapons against bombers, and the bazookas are deadly if they hit the aircraft. They can launch to operation area by using rockets like Atlas or Titan, but they can be dropped from the cargo bay of the C-130 or other cargo planes.

They can also operate from the ships or covert military bases, which can be like farms, and the only thing, what those systems need is electricity and equipment to handle those operations. Those electric power aircraft are invisible in infrared systems, and they can also be armed with stinger-missiles, what they can use against combat helicopters and other airborne targets. Those aircraft can have STEALTH-shape bodies, and they can work in sophisticated missions with other units.

NASA N-3X the next generation hybrid aviation

NASA N-3X the next generation hybrid aviation

NASA N-3X is a concept for the next generation aviation, and the thing, what makes it really interesting is that this system has basically capacity to use SCRAMJET-engines. The idea of this hybrid system that aircraft use electric powered blowers for lift-off and landing, and the flight would happen with the normal jet engines or some more exotic power systems, like RAMJET-or SCRAMJET engines.

One of the best ideas in this system is to use electric motors in lift-off and landing, and other motor systems for creating power for fast flight. The aircraft can create the fuel itself by using electrolysis if it would have electric power for the electrolyze chambers. In this case, the aircraft would use water for the source of the hydrogen. That means that if this aircraft would have VTOL-capacity it would suck the water in the tank, and then other aircraft would pull it through the air. The electric motors would work as generators and the system can separate hydrogen from the oxygen by using electrolyze process.

The thing would work that way that the aircraft would suck the water in the tank, and then the other aircraft will start to pull it by laying the cable in the same way as the airborne refueling would happen. Then the system would allow using the internal electric engine and then the aircraft will return to fill the rest of the tanks, and it can use the internal systems for creating power for electrolysis.

Turbines and ramjets are not very sharp about the fuel, and the oxygen and chlorine gas would be released to the atmosphere if the electrolyze system uses the salt water in the process. The thing to use hydrogen as a fuel is that it can produce everywhere where is electricity, and that system can installed in the aircraft itself. Fuel cells and electrolytic chambers are the very light tools, and actually, those structures can be used in both purposes. And when the speed of the aircraft would increase the induction motors can turn to windmill generators. Or in fact, the aircraft would need to equip with the power current, and that allows to take electricity for hydrogen creation system from the normal electric network.

The thing in those exotic propulsion systems is that they would need the auxiliary power system for creating electric power for the aircraft's avionics and other electric systems. RAMJET and SCRAMJET have no moving parts inside them, and that's why the motor itself is unable to create the electric power. Putting a similar flap system, what is used in V-1 (Fi-103) flying bomb in the RAMJET or SCRAMJET would allow the lift-off and land by using those motors.  This NASA concept uses only the normal jet motors, but there is capacity for those exotic power systems.

The flap system of those motors and hydrogen fuel would make possible to use those "hypersonic simpleness" in the low-speed flight, but the electric power in the system is problematic. An induction motor has one ability. They can work as motors or generators, and in this NASA concept those electric motors can lift off this vehicle and they can be used in the noiseless lift-off and flight. The fuel cells would give power to that system during slow flight, and then the motors for fast flight would be started after the aircraft is flown away from the city areas, and then the fuel injection to the motors would be started.
