| 摘 要： | 提出了运用充气气囊控制旋成体大迎角非对称分离涡的思路,并通过求解雷诺平均Navier-Stokes方程模拟了不同形状充气气囊作用下的流场,得到了充气气囊形状对旋成体侧向力的影响规律,计算结果表明充气气囊完全可以形成期望的流动干扰,为飞行器大迎角侧向力的控制探索了一条新的途径。

| Abstract: | Based on the unstructured grids,the Reynolds-Averaged Navier-Stokes equations with S-A turbulence model are solved for simulating the flow field of a revolution body at high angle of attack.Three different inflatable air cells are added on to one side of the forebody in order to investigate the effect of the air cell in side-force controlling.The results indicate that the air cell influences the flow like a forebody strake which varies the vortex structure at high angle of attack.A sharper air cell makes th... |
