This kind of ”Flying wing” can be behind some UFO-sightings

Above the text is the ”V”-shaped flying wing, what has been made for investigating the atmosphere of other planets. And of course, it can be investigated Earth's atmosphere. Those flying wings use normally hybrid motors, and in the daylight, they will use solar panels to use electric motors. This technology allows flying extreme high altitude. Electric motors don't need air, and that makes them very useful in high-flying airplanes. Also, those "flying wings might have the down looking blowers, what gives it the VTOL (Vertical Take-Off and landing capacity). 

Those flying wings have another affection, what people almost ever thought. This affection is that those motors don't leave the infrared signature on those machines. And if those ”flying wings” are made by STEALTH-material the radars cannot see them. Those electric motor-using flying wings can patrol even months in skies. And when we are thinking about ”UFO-sightings”, where people have seen ”V”-shaped object in the skies, could that object be that kind of STEALTH-drone.

When we are thinking about those aircraft, we must say that they might have attention light at the bottom, what warns other airplanes about this vehicle. Those ”flying wings” can collect the information about communication and radar signals. They might also have radars and lidars (Laser-scanners) to support their missions, and they can locate underground bunkers and submarines, what are dived under the sea. They can also guide laser-guided projectiles to the target, and send the real-time picture of battlefields to the commanders of the task force.

Those ”flying wing” -shaped ”Predators” would also operate in civil missions. They can meter the ice cab and take ozone- and other sir samples from very high altitude. And of course, those systems can observe many things in the terrain areas. Some of those test planes could be used as the test beds for the most exotic propulsion systems, where capillary would suck the air thru the turbine wheel, and that kind of propulsion can be used also in the night time. In the real world, those electric engines can also load from another plane, by using electric wire. The only thing what is different with this and hydrocarbons is that there is connected the electric socket to another plane when normal airborne refueller pumps hydrocarbon to another plane.

The prototype of those airplanes was ”Helios”, the flying wing, what was created by NASA. That flying wing was the first solar-powered airplane in the world, and it raised in very high altitude. The purpose of ”Helios” was to operate as the solar-power aircraft demonstrator, where has tested the materials and motors about those aircraft, what has very long operation time. The problem of solar power aircraft is, that those things need sunlight for their operations. But if there would be the capacity to give electric power to that system from another airplane, the operation capacity of those would be increased. And the most exotic way to create electric power would be used capillary, what sucks air thru the turbine wheel, and rotates generators inside those drones. Also RTG:s (Radio Thermal Generators) could be used, but those systems need special security, and the cesium-batteries are very expensive. The green power must not be reported to Nuclear authorities, and that's why it seems to have more capacity than RTG:s.

DARPA disk rotor hybrid helicopter

Picture 1

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.
