A high power plasma actuator with a novel approach of discharge formation was developed and evaluated as an aerodynamic control device. Trielectrode (TED) plasma actuator which utilizes sliding discharge was designed and analyzed. The researches show that the thrust generated by the TED actuator is greatly improved from SDBD actuator mode than twice. By applying high DC voltage, the induced flow can be vectored to vertical jet. The superiority of the TED actuator in the aerodynamic control was also confirmed by the wind tunnel test.
