Zhang Fuxiang; Li Kaiming; Fang Yi(East China Inst. of Tech. )
In this paper,Moire stripe displacement on shock wave resulting from real rocket exhausted plume have been clearly visualized by used of Laser-Moire deflectometry and auto-measuring pressure system.the results of density distribution on under-expanded rocket exhausted plume have been firstly obtained. The result fairly agree with the theory of exhausted plume.
