A nanosecond pulse plasma aerodynamic actuation kinetic model was presented based on its effect on flow field mechanism. The effect of nanosecond pulse plasma aerodynamic actuation on flow field was represented by fast heating of thermal source. Simulative investigation of one nanosecond pulse was performed under static flow field conditions. The simulation results show that the temperature and pressure rise abruptly in the narrow space in static flow field by nanosecond pulse plasma aerodynamic actuation. One zone is high (716K

225.95kPa) and the other one is relatively low (380K

131.7kPa). They induce a strong compressional wave and a weak compressional wave following strong and weak rarefaction waves respectively. The compressional wave and rarefaction wave propagate to the far field at a high speed (above 400m/s) and then the speed reduces soon(357m/s). Local speed is induced when the compressional wave passes by. The maximum induced local speeds in the normal and tangential directions of actuator are above 60m/s at beginning and soon reduce to about 10m/s with the reduction of compressional wave.
