Abstract

The invention belongs to the technical field of aviation structural design, and relates to an adaptive bulging air inlet channel deformation driving device based on flexible skin. The driving device comprises an inflation pump (1), an inflation pipeline (2), an inflation valve (3), a deflation pipeline (4), a deflation valve (5), an inner-side sealing cavity (6), an outer-side sealing cavity (7), a pressure sensor (8), a flow sensor (9), a skin connecting belt (10) and a basic profile mounting region (11). According to the driving device, shape change of the bulging profile of an air inlet channel in a large range is realized by using a gas pressurizing way, and the shape of the bulging profile is controlled by using pressure and flow information, so that the throat area of the air inlet channel is changed, and the problem of non-adjustability of the profile of the bulging air inlet channel is solved.

Description

technical field [0001] The invention belongs to the technical field of aeronautical structure design, and relates to a flexible-skin-based self-adaptive bulging inlet deformation drive device. Background technique [0002] In the process of designing the inlet of a supersonic fighter, the contradiction between high and low-speed aerodynamic configurations is often faced, and the stealth requirements of the aircraft also restrict the design and performance of the aerodynamic configuration of the inlet. Therefore, during the design process of the supersonic inlet, it is difficult to maintain the high performance of the inlet throughout the flight envelope. [0003] In order to solve the above design problems, the design concept of adaptive bulging inlet is proposed. The adaptive bulge inlet can adaptively change the structural shape of the pipe (bulge) in the inlet through active control technology according to the different flight states of the aircraft, and adjust the throa...
