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.

The new 3D printers are coin-size systems.

"The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation. Credit: Sampson Wilcox, RLE" (Scitech, Tiny Titan: MIT’s Revolutionary Coin-Sized 3D Printer Fits in Your Pocket) Researchers created a 3D printer that is coin-size. That kind of printer can create things like microchips. But it's possible. Those tiny 3D printers can also work in extremely large-size projects. In simplest models, the 3D printers are positioned on tracks. The 3D printer itself is the tool, that can be part of the modular production systems.  There are visions of high-temperature metal printers installed on the gantry cranes. That makes those crane printers that can make even ship-size things. The crane that the printer controls can move back and forth and the printer can move horizontally. This kind of thing can turn the crane into a high-temperature 3D printer, that

Quantum computers and ultra-fast photonic microchips can danger even the most secure communication.

"Quantum computers could pose a major security risk to current communication systems in 12-15 years with their exponentially greater speed and code-breaking ability. (ScitechDaily, Today’s Most-Secure Communications Threatened by Future Quantum Computers) Quantum computers can break entire binary cryptography. And that makes all communication unsecured. That is one of the greatest threats in quantum computing. And this brings the arms race to the quantum age. The quantum computer can create codes that any binary computer can break. But the quantum computer can also break old-fashioned codes. And that makes it an ultimate weapon and sabotage tool.   Quantum computers can change the measurements of the ammunition in factories by changing the system calibration. Or it can delete databases from the opponent's computer systems. This thing can delete all SIM cards from mobile telephones. In peacetime, the hackers that operate using quantum systems can steal the names of the counter-

Electric power innovations. Fuel cells in aircraft and solar panels over Arizona canal.

  "ZEROe teams powered on the iron pod, the future hydrogen-propulsion system designed for Airbus’ electric concept aircraft." (Intersting Engineering, Airbus's ZEROe: First engine fuel cell powers up for hydrogen flight) Electric power innovations. Fuel cells in aircraft and solar panels over Arizona canal.  Airbus Zero is a testbed for fuel cells that are used in commercial aircraft. The problem with aircraft is always noise and pollution. If the aircraft uses electric engines. That decreases noise levels and cleans the air, especially around airfields. Lightweight solar panels that can be installed on the wings and body of aircraft can give electricity to electric engines. And they can extend an aircraft's operational range.   The thing that makes this kind of system interesting is that the "flying cars" or cheap VTOL aircraft can use them as a power source. The hydrogen power cells can give energy to electric aircraft at night time. And that makes them m
