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.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like.

. The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like. Above is the image of the nano-submarine. There is introduced an idea, that this kind of system would equip with living neurons, which makes it like some kind of artificial bug or mosquito. The idea is that the robot can take the nutrient by using the robot tube, which acts like a proboscis. The neurons can get nutrients and the rest of the machine can use small fuel cells or the energy to that system can deliver by using the radio waves. Futurologists are thinking about the ideas, what the hybridization of the neurons and machine would look like? Could the hyper-technical civilization look like the group of midget submarines? Those submarines might take nutrients for the neurons, what is living in them. The purpose of the midget submarines, which might be size less than a couple of millimeters would maximize the survivability of the neurons. One of the most intere...

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...
