Experimental research of interaction of blast waveand shock wave

摘要

This paper introduces the details of experimental research of the interaction of blastrnwave and bow shock wave in the flow field of a free-flight body in ballistic range using opticalrngrating interferometry technology. The body ew from the left to the right in the ballistic rangernwhile the blast wave propagated upward from the down side to the up side of the ballistic range.rnThe paper also describes in detail the development of the flow field after the interaction of therntwo waves, gives grating interferograms of the field, and, finally, processes and analyzes thernpictures. In the area outside of the interaction of two waves, the density distributions of thernaxisymmetrical flow field of blast wave jet and a free-flight body are given.
