摘要：

在常规大气环境下，对常规、半圆和锯齿三种不同布局的等离子体气动激励器的放电特性与加速效果进行了实验研究，对不同激励参数下的频率与放电电压和频率与放电电流以及等离子体气动激励器诱导的边界层速度进行了测量。实验结果表明：当等离子气动激励器基本设计参数相同时，布局形式的改变使得放电电压和放电电流参数值发生变化，但其谐振频率保持不变，诱导气流速度则相应的发生改变；实验中还发现，半圆、锯齿等离子体气动激励器放电时离子流对绝缘材料有很强的破坏作用。

Abstract:

Under normal atmosphere environment, experimental investigation on discharge characteristics and acceleration effects of plasma aerodynamic actuators with normal, semicircle and sawtooth configurations were performed. Frequency-discharge, voltage-discharge current and the boundary induced velocity were measured under different motivation parameters. The experimental results indicate that when the basic design parameters of plasma aerodynamic actuators were given, discharge voltages and discharge currents vary with the configurations but resonance frequency keeps the same, however, the induced gas flow velocities also change. It is also found that the ion streams produced by semicircle and sawtooth plasma aerodynamic actuator have very damage effects to insulation materials.

Key words: Flow control, Plasma aerodynamic actuator, Configuration, Discharge characteristic, Induced gas flow velocity
