Description

technical field [0001] The invention belongs to the technical field of wind tunnel tests, in particular to an air inlet test simulation device and a simulation method. Background technique [0002] In the low-speed wind tunnel aircraft inlet performance test, it is a key technical link to accurately simulate the flow of the inlet; among them, in the low-speed wind tunnel without a vacuum suction system, the injection flow simulator is usually used. The injection action is used to simulate the flow of the intake port. Such as figure 1 Shown is the inlet test simulation device in the prior art. This method is disclosed in the document "Optimized Design of Cylindrical Distributed Ejector for Low-speed Wind Tunnel Inlet Test, Wu Chaojun et al., Journal of Aerodynamics". During this method, the model 1' is fixed in the wind tunnel test section by a support device 2' that can change the angle of attack and sideslip angle, and the high-speed airflow ejected to ensure that the jet...
