Abstract

To support the flow-control demands of morphing aircraft, this paper presents electrode structures with various bending angles to simulate the structural deformation of plasma actuators during operation. The experiment investigates the impact of electrode bending on the characteristics of atmospheric-pressure dielectric-barrier discharge (DBD). The experimental results show that there are two modes during the discharge process (filamentary and homogeneous) and that the electrode bending angles significantly affect the discharge-mode transition. As the electrode bending angle increases, the critical voltage for transitioning from the filamentary to the homogeneous discharge mode decreases. The numerical simulation results reveal the mechanism by which electrode bending influences the electric-field strength and discharge-mode conversion. This study provides important technical support for the application of variable-geometry electrode plasma actuators to the flow control of morphing aircraft.

电极弯曲角度对介质阻挡放电性能影响的实验研究

为了满足变形飞行器的流动控制需求，本文提出了不同弯曲角度的电极结构，以模拟等离子体作动器在工作过程中的结构变形。实验研究了电极弯曲对常压介质阻挡放电特性的影响。实验结果表明，在放电过程中存在两种模式（丝状模式和均匀模式），电极弯曲角度对放电模式转换有显著影响。随着电极弯曲角度的增大，从丝状放电模式过渡到均匀放电模式的临界电压减小。数值模拟结果揭示了电极弯曲对电场强度和放电模式转换的影响机理。该研究为变几何电极等离子体作动器在变形飞行器流动控制中的应用提供了重要的技术支持。
