Tiltable wheel flange duct propelling device for high-speed aircraft capable of vertically taking off and landing

Abstract

The invention discloses a tiltable wheel flange duct propelling device for a high-speed aircraft capable of vertically taking off and landing. The tiltable wheel flange duct propelling device comprises a disc type tiltable duct propelling structure, a C-shaped fixed duct propelling structure, a flight attitude adjusting device, a wheel flange driving motor and an integrated fan. Multi-stage series connection can be achieved through the disc type tiltable duct propelling structure and the C-shaped fixed duct propelling structure, the fan pressure ratio of the ducts is increased, and the thrust requirement of high-speed flight is met. In the vertical take-off and landing process, the stability of downward thrust is improved through the double-duct structure, and meanwhile thrust of the C-shaped fixed duct propelling structure can be converted into downward thrust through the disc type tiltable duct propelling structure. When vertical take-off and landing are converted into a horizontal flight attitude, the balance capacity of the attitude of the aircraft can be enhanced by adjusting an upper baffle and a lower baffle of the C-shaped duct and differently controlling four duct rim propulsion motors, and the safety and the stability are greatly enhanced.

Description

technical field [0001] The invention relates to a rim duct propulsion device, in particular to a tiltable rim duct propulsion device for a vertical take-off and landing high-speed aircraft. Background technique [0002] With the development of electric propulsion technology, the vertical take-off and landing methods of many vertical take-off and landing aircraft and flying cars are lift fans with fixed thrust facing downward, such as Toyota's SD-03 flying car, this design is difficult to meet the needs of high-speed flight of the aircraft , and the blades of the lift fan are too large, occupy a large space, and are also easily affected by the outside world, which is difficult to guarantee the safety of personnel and equipment. [0003] The traditional tiltable rotor uses a shaft-driven motor to drive the fan. By rotating the shaft-driven motor and its fan, the attitude switch between vertical take-off and landing and level flight is realized, or only the transmission mechani...

Problems solved by technology

However, traditional tiltable rotors are difficult to change flight attitudes, are prone to accidents, and have low safety performance. Moreover, for electric propulsion manned aircraft, it is difficult to maintain the traditional power layout and large rotor design through motor drive.

[0004] For example, the flying car of Bell Nexus Company adopts six independent tiltable shaft drive duct layouts, because the motor in the duct will affect the aerodynamic performance, and the shaft drive ducts for vertical take-off and landing are rarely designed for high speed Ducts with small inner diameters; however, ducts with large leaf diameters are not suitable for high-speed flight, and the overall structure takes up a lot of space, and the independent tiltable ducts are difficult to change flight attitudes, prone to accidents, and have low safety performance
