A new method of reducing hypersonic vehicle wave drag with laser plasma is widely research. According to the charac-ter of transient flow, Experimental systems of drag reduction with single pulse laser energy deposition in supersonic flow are set up. The interaction between laser-induced blast wave and the bow shock is recorded by high resolution schlieren system. The mechanics of supersonic vehicle drag reduction with laser is analysed. It is proved that the wave drag can be reduced with laser plasma by experi-mental method. This paper can supply experimental project for the investigation on wave drag with high-repetitive laser energy depo-sition.
