中文摘要：
基于螺旋桨的雷诺数相似和等离子体射流相似,用地面缩比螺旋桨样机模拟临近空间螺旋桨的工作状态。试验选取了两种形状的暴露电极（常规矩形激励器和新型细丝激励器）,分别对螺旋桨的转矩、静推力和功率进行了测量,并通过计算获得了功率效率和增效效率。研究表明,SDBD开启对螺旋桨产生了明显的增升减阻作用,且细丝激励器效果要比矩形激励器效果更好。
英文摘要：
Based on analogy of Reynolds and plasma induced jet,it was used that utilizing reduced propeller to simulate propeller working near space. There were two kinds of actuators chose in the experiments （regular rectangular actuator and original and power were measured through filamentous actuator）. Torque, static thrust experiments, and power efficiency, increment efficiency are calculated. Study showed that opening SDBD （surface dielectric barrier discharge） generated effect that lift increases and drag decreases obviously. Moreover, filamentous actuator acted better than rectangular actuator.
