AB - Plasma flow control, based on the plasma aerodynamic actuationgenerated by air discharge, is an active field in aerodynamics due to itspotential application in performance improvement of future aircraft. In orderto better understand the underlying physical mechanism of plasma flow control,it is important to investigate the relationship between the operatingparameters and the plasma aerodynamic actuation characteristics. This paperreports the electrical, optical and mechanical characteristics of surfacedielectric barrier discharge plasma aerodynamic actuation excited bymicrosecond and nanosecond high voltage waveforms. The nanosecond discharge ismore diffuser than the microsecond discharge and the discharge current is muchlarger at the same applied voltage amplitude. The optical emission intensity ofthe nanosecond discharge plasma is stronger than that of the microseconddischarge plasma, while the rotational and vibrational temperatures ofN_{2}in the nanosecond discharge plasma are less. Inaddition, the relative intensity of the first negative system of N_2^+(B^2Σ_u^+→ X^2Σ_g^+) and the second positive systemof N_2(C^3Π_u→ B^3Π_g)is much less in thenanosecond discharge plasma. The velocity measurements indicate that the airflow induced by the nanosecond discharge plasma aerodynamic actuation isvertical to the dielectric surface, while that induced by the microseconddischarge actuation is parallel to the dielectric surface.
