该文提出了新型的利用波动变形实现动态失速控制的有效方式。利用SST湍流模型求解雷诺平均N-S方程,分析比较了波动变形翼与刚性俯仰翼的动态失速控制的动力学特性和流动特征,并探讨了不同波动形式、折合频率、传播方式和定点位置对动态失速控制的影响。结果表明:动态失速控制中,波动翼的性能明显优于刚性俯仰翼,尤其在极大攻角部分,波动翼仍能保持较高的升力;波动翼对动态失速的控制与波动形式、传播方式、折合频率和定点位置都密切相关。
This paper presents a new effective way to realize the dynamic stall control by utilizing the fluctuating deformation. Using the SST turbulence model to solve the Reynolds-averaged Navier-Stokes equations, the dynamic characteristics and the flow characteristics of the dynamic stall control of the wavily-fluctuating wing and the rigid-wing are analyzed and compared. The effects of different wave forms, equivalent frequencies, propagation modes and fixed- The impact of control. The results show that the performance of the fluctuating wing is obviously better than that of the rigid wing in the dynamic stall control. Especially at the maximum angle of attack, the fluctuating wing can still maintain a high lift force. The control and fluctuation of the fluctuating wing on the dynamic stall, , The equivalent frequency and fixed location are closely related.
