Zusammenfassung:The present invention provides a flow field control method for a high-speed wind tunnel test on a full-size buried weapon bay. The method comprises a wind tunnel dynamic pressure-adjustment starting stage, a flow field steady-state regulation stage and a wind tunnel dynamic pressure-adjustment shutdown stage. According to the technical scheme of the invention, by adopting the flow field control method, the total pressure rate is controllable during the wind tunnel starting/shutdown stage, and the flow field fluctuation is small in amplitude during the steady-state regulation stage. 本发明提供了种适用于全尺寸内埋武器舱高速风洞试验的流场控制方法,该方案包括有风洞变速压启动阶段、流场稳态调节阶段和风洞变速压关车阶段,采用本方案的流场控制方法能够起到风洞启动/关车阶段总压速率可控、稳态调节阶段流场波动幅度小的效果。
