Experimental investigation on body force of plasma aerodynamic actuation

Plasma flow control is an innovative active flow control technology that based on the plasma aerodynamic actuation, which has become a research hotspot of aerodynamics field presently. One of the physical principles is dynamic effect. Body force, as a very important parameter valuing dynamic effect, has significant meaning for investigating the principle of plasma flow control. Experimental principle and the basic composition of the experimental system are introduced, then the body force experimental measurement of plasma aerodynamic actuation were performed. The results indicate that the body force of plasma aerodynamic actuator is on mN magnitude; with fixed actuation frequency, the body force would increases linearly with the actuation voltage increases; with fixed voltage, the induced body force is not sensitive to actuation frequency.
