摘　　要：采用基于N-S方程的CFD方法,通过计算前后平行放置的双翼和三翼的干扰流场,对悬停状态旋翼桨叶之间的气动干扰机理进行了数值探讨;在此基础上,进行了2种桨叶片数、2种桨距及2种桨尖马赫数情况的旋翼悬停流场对比计算,模拟它们对旋翼气动性能和桨叶间气动干扰作用的影响,得到一些与工程实际吻合的现象和结论。Based on the Navier-Stokes equation in CFD, the aerodynamic interaction flow fields between the paralleled twin and triple blades are simulated to investigate the aerodynamic interaction mechanism between the helicopter rotor blades in hover. Furthermore, the aerodynamic interaction flow fields of rotor blades in hover are respectively simulated in the case of two kinds of balde number, two kinds of attack angle and two kinds of Mach number to compare and analyze their influence on the aerodynamic performance and interaction. Some valuable conclusions are given for the engineering practice.
