摘　　要：研究了导弹在两种不同控制模式下,直升机下洗流场对其初始弹道的影响。通过建立直升机下洗流场数学模型和导弹动力学和运动学模型,对导弹在旋翼干扰流场下的姿态和弹道变化进行了仿真研究,给出了在导弹自动驾驶仪启控或不启控状态下旋翼下洗流干扰对导弹姿态和弹道影响变化曲线。结论认为下洗流场对导弹初始弹道的影响是显著的,导弹自动驾驶仪的控制作用可有效减小这种影响。As the airborne missile is controlled on two different modes, different influence of helicopter downwash flow on its initial trajectory is researched. The digital model of helicopter main motor downwash flow and missile dynamics was established. The variation of the missile attitude and trajectory under rotor down-wash flow are analyzed through simulation, the variety curves of them are provided on both conditions that with or without the control of autopilot. The result indicates that the rotor downwash flow has an obvious influence on the missile, but with the control of autopilot the effect can be minished evidently.
