等离子体气动激励的加速特性研究

Investigation on the acceleration characteristic by plasma aerodynamic actuation

进行了静止空气条件下等离子体气动激励加速特性的实验研究与讨论,使用皮托管和粒子图像测速仪分别对诱导气流速度进行了测量与结果分析。实验结果表明:激励参数(激励电压、频率和电极组数目)的改变,对等离子体气动激励的加速特性有不同程度的影响。进行了等离子体气动激励诱导气流加速机理的讨论,证实了等离子体气动激励作为飞行器和动力装置的主动流动控制具有广阔的研究与应用前景。

Experimental investigation and analysis on the acceleration characteristic by plasma aerodynamic actuation were performed while the ambient air was still. The induced airflow velocities were measured and analyzed with pitot tube and particle image velocimetry. The experimental conclusion shows that the acceleration characteristic changes to different extents while the actuation parameters （such as actuation voltage, actuation frequency and electrode numbers） change. The discussion on the acceleration mechanism by PIV results confirms that as an active flow control of aerocraft and power settings, plasma aerodynamic actuation has extensive research and application foreground.
