The special engine designs, what are creating the aviation of tomorrow

1) Rocket ramjet and scramjet

This type of ramjet or scramjet (supersonic combustion ramjet)can lift off from normal airfields by using Ramjet motors, where is the iris at the air inlet of the engine. When the aircraft is lifting off, the motor is using a rocket, where the oxygen and fuel would take from tanks. Or the air can inject to that combustion chamber by using the compressor. 

After that this rocket would accelerate the aircraft to Mach 1 or 2 and then the iris of the engine would be open, and internal oxygen injection will be stopped. Then the engine is taking the oxygen from the atmosphere. This kind of engine will allow that the aircraft or space shuttle can operate at the Earth orbiter and atmosphere. 

The scramjet operates a similar way. The required speed for making scramjet or hypersonic ramjet operative would be higher than using ramjets. But when the aircraft is starting to fly outside the atmosphere the iris will be closed again, and the engine turns to a rocket engine. 

 

An adjustable injection point for the fuel would make the engine more sophisticated. The adjusting can be made by using the barriers, what are adjusting the location of the fuel injector. Or there can be fixed places for nozzles that can be used for adjusting the distance of the fuel injector to the "dam", which makes the air heated, and then combustion is started. 

2) Pressure wave engines

The engines would be acting like loudspeakers. That means that there is a layer that will oscillate and send the pressure impulses to air. There is a possibility that the entire craft would be covered by using nanotechnical springs. 

Those springs can kick the gas molecules away from the craft and this can allow the craft hovering above the ground by using the pressure impulses or sound waves. The thing is that the speed of the air molecules depends on the speed of the diaphragm, when it oscillates. And that kind of system can also cross the speed of the sound. 

The entire craft can turn to a giant loudspeaker, which sends the pressure impulses around it. And adjusting the symmetry of the pressure impulses, that craft can move in every direction on the air. Sometimes it is claimed that mystery "cigar-shaped" crafts would have the oscillating outer layer, which sends the pressure impulses through the air, which makes that thing hovering. The small rocket engines would push the craft in every direction, which makes them outstanding agile. 

3) The ion engines and radiological engine

Ion rocket is the rocket, that uses the steamed metal or other ions for making the thrust. The thing is that the entire layer of the craft can cover by using small ion motors or ion accelerators. Those accelerators can be small-size nano-springs, and the ions can be driven through them. The weak thrust is the problem with that kind of system, and they could be suitable for operating in the asteroid belt. 

Electron or radio-wave engines are one choice for the interstellar rockets. This kind of system is similar to the photon rocket. But the thing, that the electron engine systems are using is the radio waves. That kind of motor can also turn the craft in every direction, what the user wants. But the weak thrust is the problem. 

4) The plasma levitation engines

This is the real "UFO-engine". The plasma is rotating around the craft and push it upwards. The system is theoretically quite simple. The thing that is needed is the ionization equipment, which is turning gas to ions.

And then the wheel-shape magnet will start to rotate those ions around the craft. That means that the plasma is rising craft above the ground, but the problem is that if the plasma is touching the electric wire, the thing, what happens is the shortcut. There is a possibility that the Kecksburg UFO in 1965 was this kind of system, which faced the failure and dropped from the sky.
