LONDON reporter Huang Chun reported in Zhuhai on November 17: China Aviation Museum in flight in the helicopter industry exhibition, there is a strange model to attract everyone’s attention. “This thing looks strange, never seen before.” Everyone was talking about. According to next-screen shows, this is a new concept of rotary-wing aircraft.
streamlined appearance, huge rotor embedded in the belly Department, after the fuselage is also equipped with a propeller, a quick look, taste and feel of amphibious aircraft. In this regard, the staff of Air secrecy: “This is just a concept machine, there are no technical parameters and indicators.”
While living in the helicopter base, but the two are two completely different kinds of models. Their biggest difference is that the rotor rotorcraft drive system is not connected with the engine, the engine is not to drive the rotor to provide lift for the aircraft, but in the rotorcraft flight in the process of air blowing from the rotation of the rotor lift. As the rotorcraft rotor rotary power is obtained by the aircraft forward. Stop the engine if the propeller does not turn in the air, and then rotary-wing aircraft, according to the inertia to maintain forward flight, and gradually reduce the speed and height, in order to ensure that the special case of out of control, enabling the crew to obtain the greatest degree of safety protection .
U.S. rotorcraft flight training manual says: “The stability of the rotorcraft is the highest of all aircraft,” which led directly to the U.S. military V-22 “Osprey” tilt rotor machine was born. In 1982, Bell Helicopter and the Boeing Helicopter Company under the U.S. Department of Defense’s multi-purpose VTOL aircraft development program (JVX plans), starting in the demonstrator based on the joint development of tilt rotor machine. Although the U.S. Department of Defense procurement plan negative attitude, it is undeniable that, compared with the helicopters, V-22 “Osprey” aircraft have greater speed advantage, it will perform in a relatively short period of time special operations commandos carried to deep within the other regions. Thanks to the power installed in the aircraft engine, as well as in level flight and hover mode of the two different flight mechanism, V-22 “Osprey” aircraft in flight acceleration and deceleration process is very rapid. Excellent acceleration and deceleration performance of the aircraft as much as possible to shorten the process of landing under fire exposure time of enemy attack. Higher flight speed, combined with terrain-following and terrain masking tactics, make V-22 “Osprey” aircraft in flight encountered the possibility of enemy attack to be much slower than flying a helicopter.
Currently, the U.S. Department of Defense and the Army have teamed to build unmanned combat armed rotorcraft (Unmanned Combat Armed Rotorcraft, UCAR) program, in order to get higher than the unmanned aircraft battlefield survival. Therefore, the timely introduction of rotorcraft aviation industry concept, also shows that the development of China’s aircraft to go in the forefront of the world.
