| 摘 要： | 探讨了直升机旋翼下洗流的形成、分布和影响。首先研究了空空导弹发射后最初阶段，穿越该下洗流区域的运动特性和弹道轨迹变化；其次研究了这种变化对空中攻击精度的影响。在此基础上还研究了降低这种影响、提高直升机空中攻击精度的方法。用某型直升机空中攻击的仿真证明，该方法是有效的。上述结论对直升机火控系统设计具有重要的参考价值。

| Abstract: | The forming, the distribution and the influence of the downwash flow on helicopter main rotor are discussed. Firstly, the flying situation and orbit changes of a guided missile at initial launching stage pass through the downwash flow are studied. Secondly, the precision influence of missile air attack on downwash flow is discussed. A method is used to reduce the influence and to improve the precision of missile air attack. It is demonstrated by digital simulation of air attack. The method is proved to be feasible and useful for fire control system design of the helicopter. |
