激光—光纤系统应用于跨超风洞蒸汽屏流态显示
THE APPLICATION OF LASER OPTICAL FIBER SYSTEM TO VAPOR SCREEN FLOW VISUALIZATION IN TRANSONIC-SUPERSONIC WIND TUNNEL
【摘要】 介绍了激光器—光纤系统在跨超风洞蒸汽屏流态显示中的应用,并得到了跨超速时的空间流态图像。说明激光—光纤系统在跨越风洞中的应用,观测激波、涡及其相互干扰是可行的,且方便可靠。
【Abstract】 This paper introduces the applicalion of laser optical fiber system to vapor screen flow visualization in transonic-supersonic wind tunnel. Off-body flow images over a missile model in transonic-supersonic speed havc beem gained. It is shown that the application of laser optical fiber in transonic-supersonic wind tunnel and the analysis of flow interference of shock wave and vortex is feasible,convenient and reliable.
