Development of High Power Plasma Actuator with a Novel Approach of Discharge Formation

研制了一种具有新型放电形成方法的高功率等离子体激励器，并对其作为气动控制装置进行了评价。对滑动放电三电极等离子体激励器进行了设计和分析。研究表明，TED驱动器产生的推力比SDBD驱动器产生的推力提高了一倍以上。通过施加高直流电压，可以将诱导流转向为垂直射流。风洞试验也证实了TED作动器在气动控制方面的优越性。

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.
