## A FULL PHASE DYNAMIC MOTION MODEL OF BOOST–GLIDE VEHICLE

• 摘要: 建立了一种助推–滑翔飞行器的全程运动模型，首先给出了笛卡尔坐标发射系下主动段和极坐标地心系下滑翔段的质心运动学方程，然后推导了不同坐标系之间衔接点坐标转换模型，构成封闭的全程运动模型。最后开展了助推–滑翔全弹道仿真，验证了衔接点前后不同坐标系下弹道变化连续性。在给定发射点参数和弹道控制变量的条件下，基于全程运动模型可获得全程弹道及滑翔段机动覆盖范围，用于支撑助推–滑翔全程弹道优化设计以及助推–滑翔飞行器的全程机动能力快速评估。

Abstract: A full phase dynamic motion model of boost–glide vehicle is established in this paper. Firstly, the translational equations which include boost phase equation in Cartesian coordinates and glide phase equation in polar coordinates are promoted. Then the formulation of link point between the two phases in different coordinates is derived to cover the full dynamic motion model of boost–glide trajectory. At last, the continuity of the trajectory between different coordinates is demonstrated by full phase trajectory simulation. Given launch point parameters and control variables of the trajectory, the full trajectory and footprint of glide phase can be obtained based on this model to support the trajectory optimization and fast evaluation of maneuverability for boost–glide vehicle.
