垂直发射旋转导弹空中转弯控制技术研究

Study on Aerial Turn Control Technique of Vertical Launching Rolling Airframe Missile

对垂直发射舰载末端防御旋转导弹的空中转弯控制技术进行了研究。采用侧向力控制,结合脉冲发动机与弹体高速旋转特性设计了一种转弯控制方式,利用弹体旋转调整脉冲发动机喷射方向,实现导弹在特定方向的快速低头,降低俯仰角,并依靠反方向回喷抑制俯仰角速度,使导弹快速稳定。通过调节控制参数(脉冲发动机数量)可控制导弹转弯结束后的俯仰到位角,有效打击不同态势的来袭目标,脉冲发动机数量越多,控制参数的取值范围就越大;可用俯仰到位角越多,到位角精度越高。基于RAM Block 2导弹进行近界弹道仿真,结果表明:采用提出的转弯控制方式,导弹的转弯速度快,能保证近界和低空作战性能,在工程中有较好的应用前景。

The aerial turn control technology of ship-borne terminal defense rolling airframe missile with the vertical launch mode was studied.The side force control was adopted.A control scheme was designed which combined the high-speed rotation characteristic of the missile and the pulse engine.The missile rotation was used for adjusting the direction of the pulse engine to achieve the missile turning rapidly in a particular direction,reducing the pitch angle,and suppressing the pitch angle speed relying on back spray in the opposite direction,which could make the missile stabilizing rapidly.The final pitch angle could be controlled by adjusting the control parameters(the number of pulse engine)in order to attack the target at different positions effectively.The more pulse engine,the larger control parameter scope,the more available elevation angle of incidence,the higher accuracy of angle of incidence.The near-boundary trajectory simulation based on RAM Block 2 missile was carried out.The results show that the scheme proposed is effective and can guarantee the near-boundary and low-altitude combat performance of the missile,which has a good application prospect in engineering.
