多针-网电极离子风激励器推力与推功比的实验研究

摘要

The thrust of ionic wind exciters in 19 points-grid and 31 points-grid electrodes configurations was measured in this paper by means of air suspension test platform without friction. Meanwhile, a control method was also provided for multipoint-grid ionic wind exciter. And then the study was done on the factors, e.g. the gap of point-grid electrodes, the spacing between points, the curvature radius of the point, and the voltage, current of corona discharge, all of which may affect the thrust character; so some methods for getting high thrust at low power were also proposed in order to improve the thrust and the thrust per unit power at the same time.%　　本文搭建了一种无摩擦气垫悬浮测试平台测量了19针和31针-网电极离子风激励器产生的推力特性，为多针-网电极离子风激励器作为新型动力源提供动力控制方法。通过研究多针-网间隙、针-针间距、针尖曲率半径和电晕电压电流对离子风激励器推力特性的影响，提出了在低功耗下产生较大推力的方法，改善离子风激励器对低功耗与大推力的需求不能同时满足的现状。
