固体动能拦截器助推段飞行方案研究

针对三维空间内的高速飞行目标,提出了一种可用于固体动能拦截器助推段的导引方法。建立了固体动能拦截器与目标的相对运动关系模型,分析确定了转移轨道的约束条件,并在此基础上推导出转移轨道的轨道根数计算方法。同时根据拦截器的待增速度给出了助推器推力矢量方向的确定方法。仿真结果表明,该方法能有效实现固体动能拦截器助推段的制导控制。

Research on flight scheme of solid propellant kinetic kill vehicle in boost stage

Aiming at the high-speed flight targets in three-dimensional space,a guiding flight method used for solid propellant kinetic kill vehicle(KKV) in boost stage was put forward.The model of the relative movement between target and KKV was derived,and constraint conditions of the transfer orbit were analyzed and eetermined.On the basis of the results,calculation method for elements of the transfer orbit was derived,at the same time,determination method of booste thrust vector was given according to increasing-required velocity of KKV.The simulation results show that the guidance of KKV in boost stage can be realized by means of this method.
