| 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. |
