摘　　要：等离子体流动控制作为一种新概念主动流动控制技术,其物理作用依据之一是'动力效应'。体积力作为表征'动力效应'的重要参数,对研究等离子体流动控制的原理具有重要意义。介绍了实验原理及系统的基本组成,对等离子体气动激励体积力进行了实验测量。结果表明:体积力的大小在mN量级;固定激励频率,激励电压增大时,体积力增大,且线性关系非常明显;固定激励电压,体积力受激励频率的影响不大。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.
