Sixteen Propellers! Chinese version of Osprey Sci-fi Exposure Live Demonstration of Deformation

 Sixteen Propellers! Chinese version of Osprey Sci-fi Exposure Live Demonstration of Deformation

[Global Network Reporter Xu Luming] The Tianjin Direct Expo opened on October 10, 2009. In the exhibition area of the Aviation Industry Group, a model aircraft equipped with 16 propellers was noticeable. According to reports, this is an electrically driven multi-propeller tilting high-speed rotorcraft, which integrates the concept of tilting wing and distributed electric drive to achieve a flight speed of more than 600 km/h. The aircraft adopts tandem tilting rotor configuration. Sixteen electrically driven rotors are installed symmetrically on two pairs of wings, of which 12 are used for vertical takeoff and landing, many are distributed on the front and rear wings, folded and collected at high speed forward flight, and four electrically driven propellers for forward flight propulsion and low speed attitude control are distributed at the front and rear wing tips.

The aircraft has three main technical characteristics: tilting wing design, vertical takeoff and landing and high-speed forward flight; rotor and propeller classified design, taking into account both vertical takeoff and landing and high-speed forward flight performance; electric drive mode, easy to use and maintain. Because of the electric drive mode, there is no complicated mechanical transmission, and maintenance is more convenient.

At present, in the military field, the United States is at the forefront of the world in the application of tilt-rotor aircraft, currently equipped with CV-22, MV-22 Osprey tilt-rotor aircraft. Although the flight safety of the V-22 series tilt-rotor aircraft has been criticized, it is undeniable that this aircraft, which combines helicopter vertical takeoff and landing with fixed-wing high-speed flat flight capability, has significantly improved the rapid transportation deployment capability of the U.S. Army. At the same time, the newly developed V-280 Brave tilt-rotor aircraft in the United States is also participating in the tender for the next generation of U.S. Army general helicopter project. The tilt-rotor aircraft in the future is likely to become the main equipment of U.S. military air tactical transportation.

However, one of the major problems faced by tilt-rotor aircraft is the complexity of mechanical transmission structure, followed by high failure probability, which directly affects flight safety. Japans Self-Defense Force has also introduced V-22 tilt-rotor aircraft from the United States to strengthen the seizure of islands combat capability. However, because the flight safety of the aircraft has been pending, the SDF can only stay in the United States for training after receiving the V-22 rotorcraft, and can not return to China for deployment. In contrast, the multi-propeller tilting high-speed rotorcraft exhibited at this direct exposition adopts a much safer and more reliable electric drive mode.

At the exhibition site, the staff demonstrated the process of the wing switching from horizontal to vertical, giving people the feeling of future technology in the movie, which is quite sci-fi. According to the field personnel, this multi-propeller tilting high-speed rotor aircraft is under development. The propeller folding technology used in this aircraft is relatively advanced all over the world. Besides the ability of vertical takeoff and landing, short takeoff, it can also achieve high-speed flight, and can effectively carry out fast and long-distance transportation tasks. It will have better application prospects in military and civil fields in the future.

According to the on-site information, the aircraft can achieve a flight speed of more than 600 km/h, which is much faster than the current maximum flight speed of 509 km/h for the U.S. V-22 tilt-rotor aircraft and 504 km/h for the V-280 aircraft.
