Description

technical field [0001] The invention relates to an integrated test model for force measurement of an air inlet, and belongs to the technical field of aviation aerodynamic wind tunnel tests. Background technique [0002] Intake duct is a general term for a system, including air intake, auxiliary air intake, air discharge port and air intake passage, and is an important part to ensure the normal operation of the engine. The inlet test is an important wind tunnel test technology, mainly to measure the total pressure recovery coefficient of the inlet under various flight conditions, the flow coefficient, the uniformity of the flow field at the outlet of the inlet, and the surface pressure coefficient along the inner pipe. Wind tunnel dynamometer test is the most conventional wind tunnel test technology, and the aircraft profile is selected by measuring the aerodynamic force with a balance. In the design of the intake port, in addition to the test of the intake port, it is also ...
