DARPA disk rotor hybrid helicopter

When we are talking about the fundamental way to make airplanes, we must realize that the problem with making the aircraft is that there is no way to make perfect airplanes. All the models of airplanes are some kind of compromises, because there are not the models, what are suitable for every action, what the airplane might want to have.

If the airplane is fast, it will need another kind of motor, then slower airplanes. The answer to the problem is the VTOL (Vertical Take-Off and Landing) technology. This kind of technology is already used in the AV-8 Harrier II and F-36 VTOL-versions. But using the turbojets has the problem, that those motors are very noisy, and that’s why must create new kind of technologies, what can be used, to make the new era of the VTOL-airplanes.

The idea of this concept is actually very simple. Just put the helicopter rotor on the roof of the airplane. Another way is to put the blower in the body of the aircraft, but that decreases the capacity to carry cargo or fuel if those blowers are in the wings of the aircraft. If blowers are in wings, they might cover by hatches, what can be closed, when the jetplane will go flying at high speed.

The problem with connect the helicopter and jet airplane is that the rotor must not rotate too fast or it will be the crash, and the answer is to put the disk on it. In the DARPA concept the disk will increase, when the rotor is going to round faster, and when the aircraft will decrease the speed, and the rotating speed of the rotor is decreasing, will the disk become smaller, and it will give more power to the main rotor of this hybrid airplane.

That thing can fly same speed as an airplane, but when it must be land or float on some spot on earth, it won’t keep more voice than the normal helicopter. And in one idea of using the disk on the rotor of the helicopter, can be made new kind of the system: AWACS (Airborne Warning And Control) helicopter, what can use as the same missions than E-2 ”Hawkeye” or E-3 ”Sentry”. The system might be remote controlled by operators from the earth, and it might be so sophisticated than full-scale AWACS systems.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
