Numerical Study on Process of Drag Reduction by Laser Plasma in Supersonic Vehicle

Interaction between laser plasma and bow shock wave in front of supersonic vehicle is analysized. Physical and mechanical model of laser plasma energy being deposited in supersonic fluid field is established and computational code is programmed. Process of drag reduction by laser plasma in supersonic vehicle is simulated numerically, and the mechanism of laser plasma reducing drag is disclosed. Simulated results are compared with relative references’, which agree well with each other. It is illuminated that drag reduction by laser plasma can be studied by the established model and code.
