Abstract

The invention belongs to the technical field of aviation structure tests, and particularly relates to a strength test device of a deformable bulge air inlet channel structure. The device comprises a test frame, a test piece, a deformation driving mechanism and a pressure box loading assembly. A preset distance is formed between the two bearing beams, the test piece fixing rack is mounted on the two bearing beams, and an opening is formed in the test piece fixing rack; a hinge is arranged on the test piece, and the test piece is fixedly arranged on the test piece fixing rack by matching the hinge with a fastener; the deformation driving mechanism is arranged between the two bearing beams, the bottom of the deformation driving mechanism is connected with the bearing terrace, and the top of the deformation driving mechanism is connected with the test piece; the pressure box loading assembly covers the test piece, the pressure box loading assembly is fixedly connected with the test piece fixing rack, and the pressure box loading assembly is provided with a containing cavity with controllable pressure. The intensity of the deformable bulge air inlet channel under different postures corresponding to different Mach numbers can be verified.

Description

technical field [0001] The application belongs to the technical field of aeronautical structure testing, and in particular relates to a strength testing device for a deformable bulged air inlet structure. Background technique [0002] The deformable bulging inlet can adjust the shape of the inlet according to the flight environment of the aircraft, thereby controlling the amount of air intake, and has a good application prospect for aircraft pursuing high speed and high maneuverability. Compared with the traditional fixed bulge inlet, the deformable bulge inlet can control the throat area of ​​the inlet by adjusting the height of the profile, so that the engine has good launch matching performance in a wide speed range. While retaining the advantages of the fixed bulge air intake, it does not increase too much weight and volume occupation, which is helpful for the comprehensive improvement of engine performance. [0003] In order to verify the strength of the intake duct st...
