| 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-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 discharge 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. |
