| 摘 要： | 纵列式双旋翼直升机的旋翼尾迹受前飞自由流、机身和旋翼之间的干扰影响,旋翼尾迹不仅影响机身的空气动力,也影响旋翼自身的空气动力特性.应用欧拉方程与计算流体力学(CFD)方法,采用自适应非结构直角网格技术生成计算域网格,数值模拟纵列式双旋翼直升机全机流场,给出了考虑旋翼影响的机身表面压力分布以及全机流场特性.

| Abstract: | The aerodynamics of fuselage and rotor were disturbed by rotor wake because the strong interaction between rotor wake and forward airstreams,fuselage and rotor.A Computational Fluid Dynamics method based upon the solution of Euler equation and adapted unstructured grid was used for the numerical simulation for the flow field of tandem rotors helicopter.The pressure of fuselage and rotor thrust,helicopter flow field have been given. |
