| 摘 要： | 在较高风速下研究介质阻挡放电等离子体气动激励对翼一身组合体绕流流动的控制效果。结果表明：在来流风速100m／s的情况下，介质阻挡放电等离子体气动激励能较好地抑制流动分离，失速迎角推迟约30％，升阻比最大提高80％。研究结果为等离子体流动控制技术的应用奠定重要基础。

| Abstract: | Suppression of stall separation on a wing-body combination by dielectric barrier dis- charge plasma was investigated at high wind speed. The results show that the dielectric barrier discharge acting on the surface of the wing-body combination can obviously suppress the boundary layer separation at the freestream flow velocity of 100m/s. It was found that the stall angle was delayed by about 30 %, and the lift/drag ratio increased about 80 %. In the future, the results can lay a foundation for the application of plasma flow control technology. |
