摘要
机载导弹发射技术是察打一体无人机的关键技术,因此导弹发射对小型载机的扰动成为人们关心的内容;考虑导弹和发射架之间的接触间隙,采用多体动力学理论中的Schiehlen方法,建立了机载导弹发射的多体动力学模型,对察打一体无人机的机载导弹发射进行了仿真;研究和分析了察打一体无人机对机载导弹发射的响应特性和影响机载导弹离轨姿态的因素,为该类无人机的控制系统设计提供了依据。
Launching of airborne missile is a key technique of reconnaissance and strike integrated UAV.The disturbed motion of the small aircraft caused by missile launching has got considerable concern.With the clearances between the missile and launcher,the multibody model of airborne missile launching from UAV was built and simulated.The response characteristic of reconnaissance and strike integrated UAV to launching of airborne missile was studied.The factors effecting the attitude of missile separation from launcher were analyzed.The conclusion of simulation has provided basis for designing corresponding control system.
