Abstract

The invention discloses an air inlet channel main bearing structure and an air inlet channel main bearing structure deformation control method. According to the air inlet channel main bearing structure, a main bearing structure (1) is made of a memory alloy; the main bearing structure (1) is a cantilever supporting beam; one end of the main bearing structure (1) is fixedly connected with a fixing supporting structure (2); the other end of the main bearing structure (1) is a free end; the material fibre direction of the main bearing structure (1) is perpendicular to the fixing supporting structure (2). The air inlet channel main bearing structure deformation control method is used for controlling the deformation of the main bearing structure (1). The air inlet channel main bearing structure and the air inlet channel main bearing structure deformation control method have the advantages that the main bearing structure of an air inlet channel can deform repeatedly in a certain range, so that a lip can deform repeatedly in a certain range; suitable deformation of the air channel main bearing structure is set according to actual flight speed, so that the problem that a lip structure in the prior art cannot be adjusted is solved; therefore, the air channel has optimal pneumatic performance and starting matching characteristic under different flight states.

Description

Technical field [0001] The invention relates to the technical field of aerospace structure design, in particular to a main bearing structure of an air inlet and a method for controlling deformation of the main bearing structure of the air inlet. Background technique [0002] For an aircraft with a maximum flight M number of supersonic speeds, the problem of intake port / engine matching is always a thorny issue. When the aircraft is at a standstill to taking off, the incoming flow speed gradually increases from zero. Because the incoming flow speed is very low, the airflow entering the intake duct will be sucked in from the surrounding environment, causing the airflow in the intake duct to separate and the lip of the intake duct The thinner the airflow is, the more serious the airflow separation will be, which will cause the blockage of the intake throat, increase the distortion of the flow field at the engine inlet, increase the total pressure loss, increase the thrust loss, and i...
