空间飞行器撞击交汇模型研究

摘要

The space vehicle is divided into target and projectile, encounter model is studied during impact course of them. On the basis of target constitution analysis,the target equivalent model is built up based on basic geometric shape mathematic description of the typical target is realized. Projectile terminal guidance model is established with RTPN (Real Tree Proportional Navigation), then encounter models are set up between projectile and typical equivalent targets respectively, and characteristic projectile-target encounter paraneter solving process is given. The case is analyzed the result of study lays a foundation to assess impact damage effectiveness.%将空间飞行器分为目标和射弹两类,对二者撞击过程中的弹目交汇模型进行研究.在目标构型分析的基础上,基于基本几何形体建立目标等效模型,实现了典型目标的数学描述.考虑弹目构型特征,采用真实实际比例导引建立射弹末制导模型,在此基础上,分别建立射弹与典型等效目标的交汇模型,给出了典型弹目交汇参数的求解过程.进行案例分析,研究结果为撞击毁伤效果评估奠定了基础.
