Title:
INTERNAL-EXTERNAL FLOW DECOUPLED DUAL-WAVERIDER HIGH-SPEED AIRBREATHING AIRCRAFT AND GENERATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/095163
Kind Code:
A1
Abstract:
An internal-external flow decoupled dual-waverider high-speed airbreathing aircraft, comprising an aircraft body. A Bump forebody is provided on the upper surface of the aircraft body, a high-capacity waverider is provided on the lower surface thereof, and an air inlet passage, a combustion chamber and a nozzle are provided inside the aircraft body, the air inlet passage being a high-external-compression-ratio internal-waverider air inlet passage. In the internal-external flow decoupled dual-waverider high-speed airbreathing aircraft provided in the described technical solution, the air inlet passage and the waverider are respectively arranged at upper and lower sides of the aircraft body, and the pneumatic decoupling of a waverider flow field and an inlet flow field of the air inlet passage is achieved by means of the decoupling in a geometric layout, avoiding the problems of low design efficiency and large external resistance of a non-design point caused by strong coupling of internal and external flows, significantly increasing the pneumatic design efficiency of a high-speed airbreathing aerospace aircraft, and effectively solving the problems in the existing internal-external flow coupled aircraft of the difficulty in balancing the total counterweight/torque, the reduction of the thrust of the aircraft when the air inlet passage moves downwards, the limited flow direction arrangement range of the air inlet passage, and the limitation of the total length of the aircraft.
