Windmill starting test method for high-speed wind tunnel aircraft propulsion system

The invention belongs to the technical field of high-speed wind tunnel tests, and discloses a windmill starting test method for a high-speed wind tunnel aircraft propulsion system. The test method relates to a temporary impulse type high-speed wind tunnel, an air inlet channel, a measurement and control device of the air inlet channel, an aero-engine, an engine pedestal and other devices, and comprises five test processes of engine starting and warming-up, windmill condition establishment, propulsion system windmill starting, wind tunnel flow field exiting and engine vehicle stopping. According to the test method, through cooperative control of the wind tunnel equipment and the aircraft propulsion system, assessment of the windmill starting capability of the aircraft propulsion system is realized. The test method solves the problem that the operation time of the transient high-speed wind tunnel cannot meet the test operation time requirement of the aircraft propulsion system, and compared with a traditional f
