Laser plasma drag reduction technology is of great significance for hypersonic aircraft drag reduction and thermal insulation and improves aircraft performance.The numerical calculation model and experimental research method of pulsed laser drag reduction research are introduced; The mechanism of laser-plasma drag reduction is summarized; The influence of key parameters such as incident laser energy,energy deposition position,and flow field Mach number on drag reduction performance is discussed.Given the current research status,suggestions are put forward to establish the relationship between the key parameters of plasma hot core and the effect of laser drag reduction.
