| 摘 要： | 为了进一步提高等离子体激励器可控雷诺数,采用测力以及粒子图像测速(PIV)等研究方法,从二维机翼到三维半模,从低雷诺数到高雷诺数,开展了对称布局式介质阻挡放电(DBD)等离子体激励器控制超临界机翼气动特性的试验研究,分析了控制机理,实现了等离子体"虚拟舵面"的功能。结果表明:在雷诺数为2×106的情况下,对称布局式等离子体气动激励能较好地抑制超临界机翼绕流流场分离,使失速迎角推迟2°,最大升力系数提高8.98%。

| Abstract: | In order to improve the plasma actuator authority at higher Reynolds number, a test investigation is conducted to evaluate the effect of symmetrical dielectric barrier discharge (DBD) plasma actuators on a two-dimensional supercritical wing and three-dimensional half model using force measurement and particle image velocimetry (PIV) at different Reynolds number. The controlling mechanism is analyzed and the function of "Virtual Section Shape" by plasma actuator is achieved. The results show that the flow separation around wing can be obviously suppressed by the symmetrical plasma actuator at Reynolds number 2×106. It turned out that the stall angle of attack is delayed by approximately 2° and the maximum lift coefficient is increased by approximately 8.98%. |
