HCM (Hypersonic Cruise Missile) and the sixth-generation aviation

Kimmo Huosionmaa

When we are thinking about the HCM (Hypersonic Cruise Missiles) like Boeing aircraft corporation X-51 "Waverider" concept would this same technology allow creating the new kind of aircraft, what would fly extremely fast in the atmosphere, and then jump to the LEO (Low Earth Orbiter), where that aircraft can maneuver by using small rocket motors. In fact, the paddle-scramjets can be used also as the rockets. During the slow flight, the front paddles of the scramjet will keep closed, and the oxygen with hydrogen will be injected into the motor, and then the electric arc will start to burn that mixture.

Because the speed of air through the scramjet is too slow, that the spontaneous burning would begin, would the oxygen injected inside that tube by using compressors, and electric arc would detonate that mixture. When the speed of the aircraft will rise about to speed of Mach 8 would the flap in the front open, and the spontaneous fire will start to burn in the hypersonic ramjet. There are of course the technical problems with this system, but this kind of version would be very useful in theories.

When the altitude would rise enough high, the front paddles would be closed, when the aircraft would travel so high, that the air pressure would be too low, that the aircraft can not use oxygen from the atmosphere, and then the internal oxygen and hydrogen would start to inject in the scramjet motor. The maneuvers in the orbital trajectory would be made by using the helm, what is in the jet tube. And that would allow creating the shuttle, what will be a mixture of the space shuttle and aircraft.

The thing about that kind of spacecraft is that their cabin might be non-pressurized, and the pilot might use a space suit, what allows to make the structure of the cabin lighter. When we are thinking about the motor systems, there are of course many other things how to create those motor system. And one is to start the flight with standard jet-engines. After that, the system would transfer to use ramjet-engines, and after that, the scramjets would start to operate. This kind of aircraft could revolutionize many things in the military and civil space projects and aviation.
