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 moon shuttle concept of the future could also operate as the moon car

The moon shuttle concept of the future could also operate as the moon car 

Very interesting solution for Moon car would be the moon shuttle, what have wheels, which allows the vehicle to operate as the car on the surface of the moon and fly directly back to Earth. There is one very interesting detail in Moon vehicles, and that is that the solutions are always so complicated.

Why those vehicle concepts, what are meant for traveling on the surface of the moon are not equipped with rocket motors, that they could fly and drive with the wheels at the same time? The thing that the Moon lander could land and operate as the moving base, what can fly to Earth without the crew need to change the vehicle?

The construction is simple, the Moon car, or how those vehicles are called would be equipped with the rocket motors, what are below that vehicle, and the normal motor what would thrust backward? Or actually when we are thinking the things too complicated, and we always forget that there is no air, and there is no friction in the vacuum. 

That means that the device could flight in every angle and that means that the shape must not be aerodynamic. So the rockets, what nozzle would face down would also drive the craft to earth. And that would probably cause the artificial gravity in the vehicle. That vehicle would also have wheels, that it can also drive on the surface on the Moon like a car.

The benefit of those systems is that they could load the moondust to the cargo bay, and fly to Earth with this cargo. Those simple solutions are very interesting because if we someday in the future would use Moon as the commercial purposes, the thing what we would look for is the Helium 3 and other minerals. And that material can load to those shuttles ad those vehicles would fly them to Earth.

This is one of the interesting ideas of the systems, which can be used as the transporters. And they can transfer tools to Moon for making the railgun, what will shoot the manganese and other materials to Earth in capsules. But that kind of visions of the magnetic railgun, what makes traveling easy and cheap are somewhere far in the future.

How to make a car-VTOL-aircraft hybrid?

How to make a car-VTOL-aircraft hybrid?

1. Flying cars are awesome things

When we are thinking about the low-price flying machines, we have always forgotten that the system can have the module structures. That means that the wings and auxiliary jet motors can be removable.

This kind of vehicles are near the normal aircraft, and the idea is that those wings and other tools can pull by using the roller coaster. And then they can be connected to place, where they are flying.

2. The blowers, what blows to every side would turn the vehicle in the right position on the air. 

There have been tested the cars, which have blowers on the bottom, but the problem with those vehicles is a balance. If the thing turns to the wrong position. In those cases, the vehicle will be in a very dangerous situation, if there is no ability to turn them in the right position.

That causes the bad situation, and this problem has been tried to solve by installing blowers to each side of the vehicle, that would turn back in the right position. That propel-systems will make that vehicle extreme agile and increases the capacity of those vehicles.

3. What works with the scaled model, works also with full-scale models

The thing is that everything, what works with the scaled-models, operates also with full-scale models. This is an idea of engineering and the topic of this text is taken from the film, where is introduced the RC-model, which operates as well as the car and helicopter.

The full-scale model, where people can sit inside can be done by using the same introductions, what is used in this film, and the result could be really interesting. When we are thinking about the room, what this vehicle takes, we must understand that the modular solution, in this case, would make the thing fully operational.

4. The modular structure means, that the wings can be removable, and they can connect back when the user wants to fly.

That kind of vehicles is sometimes blamed because they are taking really big space. But in real life, the wings can be equipped with fast attachment. That thing means that the wings can pull in the roller-coaster when there is no need to use them, and then they can put on their position.

I sometimes have thought, that also things like ground-effect and normal wings can also install the aircraft, what is looking like cars. And those things might be used with the same bodies. if we want to think about the situations, where the vehicle would need very high speed, that could be solved by installing the jet engine on the roof, and that thing can also be removed.

Jedi is very easy to create by using modern technology.

Jedi is very easy to create by using modern technology.

LRAD technology would allow creating silent VTOL craft.

In the modern era, we have the technology, which can make many things, what we think true. In this text, I will think about artificial intelligence, and the technology, what could make people believe, that they have some kind of supernatural skills or abilities. By using modern technology, we might want to create the "techno Jedi", what basis the thing that the aircraft, or whatever the Jedi must levitate is only the machines, what are following some gestures.

Those marks will activate the motors and other things, and then that thing would seem impressive. That craft might have the vacuum machine, which makes people levitate by using one kind of vacuum cleaner, what just sucks targeted person above the ground. When we are thinking about the scene, where Yoda trains Luke Skywalker, we must realize, that the home planet of those fictional characters would be different.

The effect with superpowers would happen if a human would step on the Titan moon, and the weak gravity would create an effect of superpowers.

And if that planet would have weaker gravity field that the home planet of the trained Jedi, would that mean that this person would believe to own superpowers. The situation is the same as a human would go on the surface of Titan moon, and there would be the possibility to show the extreme strength because the gravity of the giant moon is much weaker than gravity field is on earth.

 The gravity field of that moon is so weak, that the escape velocity is 0,138g (0,835 moon gravity), but the escape velocity is 1,11 times higher than the moon, because of the thick atmosphere. That means that the 100 kg object weight on the surface of Titan is 100 X 0,138=13,8 kilogram, which means that the personal vehicle, what weight is 1000 kilograms would weight 138 kilograms on Titan (1000 X 0,138=138), and there every human would have superpowers.

Do you like music videos or Star Wars movies, you might want to know this thing, by suings the modern human technology could scientists and engineers create the things, what might look like some kind of "Jedi training". The thing, what those people would create is a gesture-controlled aerial vehicle, what would act by some way, when the person would show it the mark. And those clothes would operate as the electronic key, which allows the craft to operate with those shadow protocol operations. That means that if the person would not have the right clothes, they would not be allowed to get in those control algorithms.

The key element is the gesture control

That kind of things are similar, what is used to control the mobile telephones or laptop computers, and the person must go to the eye of the camera and make the sign like rising the fingers, and then the craft would do, what the thing is ordered to do. It might find the sign of the weapons, and then it might just point the magnet field to that thing. And then the metal would be crushed by using another magnet.

The craft must be silent, and that thing would operate by using small jet-engines and LRAD-systems, what would make it feel like a silent because the noise of the engines is suppressed in the very small area. And when we are thinking about the "Jedi training", you might look at the music video below, and you might think that the trainers would be robots. This means that there is artificial intelligence, which might have orders to make something different than with another person.

The new kind of modular transport aircraft would be the hybrid

The new kind of modular transport aircraft would be the hybrid

Sometimes there have been discussions about the new kind of modular cargo plane. In that concept, the cargo plane has two parts, the independent cargo modules what might bring in the airfield by train, and then those modules would just load inside the cargo plane, what could be used for the long-range transport. Those cargo modules can be made for cargo, or they can have equipped for passenger modules. In wildest dreams, those modules can flight independently to the long-range cargo plane, and that means that those modules can load in somewhere else.

The idea of the VTOL transport would be the quadcopter type vehicle, what can fly straight in the other aircraft by using the similar hatches what the space shuttle uses. In this concept is the two aircraft. The bigger one what is meant for the fast and long-range transportation and the other vehicles are actually the cabins, what can fly straight in the bigger aircraft. And maybe this thing seems quite complicated but I will write it in here because it seems interesting. By using those modules would the same long-range cargo plane carry either passengers or cargo.

And those VTOL (Vertical Take Off and Landing)-planes or modules could be made that way, that they can carry also by using railways. This means that this kind of system allows loading passengers or cargo far away from the airport, and then the train will bring those modules near the airport. Then those capsules will fly to the transport plane by using electric motors. And that would be a very radical concept. But as you see this kind of visions are very uncomfortable and difficult to make, but maybe after 20-30 years later they are in everyday use. Or they might be lost in history.

There are a couple of examples of the things that have been very good, but they have just forgotten. And this kind of modular hybrid solution for the next generation cargo and civilian aviation could be too revolutionary. There are many things, which makes this thing safer and cleaner than any automobile, because of all parts of the transportation system are operating with clean energy.

The trains and VTOL-modules can use electricity and how clean the electricity is depended on the way, how the electricity has been produced, and the long-range transporter can use hydrogen as the fuel. Hydrogen is a clean fuel and the thing, what is left behind the hydrogen motor is water steam. This makes it a very suitable fuel in aviation, but why not in turbines of power plants and cars cannot use this fuel, what is environment-friendly.

The "flying rugs" or the layer shape aerial vehicles are actually exist


Kimmo Huosionmaa

When we are talking about the plate or rug shaped flying machines, they might exist. The thing is that in this kind of flying machines may have the layer, where are the blowers installed it.  The layer is created for high-speed evacuation and transport system for civil and military purposes. Those flying layers can carry many people in the cases, where is hurry to evacuate buildings or offshore oil rigs. That flying layer can also be used for rising the equipment and crew in the upper floors of the of the tall buildings, and also they can be used as the scaffoldings. Those layers can actually be made by using the painting trays, and the system would need only blowers, what would blow air to the ground.

The horizontal movements would be done by tubes, where is the propeller, and there is needed four vacuums and tilt angle recognition sensor, which would help to stabilize this thing. In fact, there are claiming that some intelligence services have this kind of systems for burglary and other kinds of things. And maybe those systems are covered by the rug, what hides that thing. But big size "helicopter layer" can also be used for landing equipment in a certain area, and that thing can be used for many other duties like flying vantage point. Those layers can also lay on the motorway and rise the car to the air. If that system would be equipped with hydraulic tunks, they can rise even the heavy vehicle from the layer, and that makes possible to abduct people.

If the doors would be locked by plates, the people would be trapped inside the vehicle. And then the needed thing is the aircraft or aerial vehicle, which is big enough to take that kidnapped vehicle inside, and they must have the capacity to lay over the ground. Maybe that thing could be the tilt-rotor version of the military cargo-plane like C-130, An-12 or C-119, what can be used in this kind of actions.  But sometimes I have thought that also extraterrestrials if they exist can make copies of the famous aircraft, and use them as the undercover UFO:s.
