末端区域能量管理是重复使用运载器实现精确无动力水平着陆非常重要的一个飞行阶段。本文将末端区域能量管理段水平轨迹和纵向轨迹分开设计，参数化的水平轨迹设计包含3个校正圆，以实现航向、航程以及位置的精确调整；纵向轨迹采用2段二次高度-航程曲线以实现对高度和速度的控制。在此基础上，给出了水平和纵向轨迹的跟踪制导方法。仿真结果及其分析表明该轨迹设计方法可以灵活地设计末端区域能量管理段的标称轨迹，且制导方法能够实现标称轨迹的良好跟踪。

Terminal Area Energy Management ( TAEM) is a critical flight phase that brings the unpowered Reus-able Launch Vehicle ( RLV) to realize accurate horizontal landing.The horizontal and longitudinal trajectory are de-signed respectively in this paper; the parameterized horizontal trajectory design include three correction circles to adjust accurately heading, range and position;the longitudinal trajectory uses two separate quadratic polynomials to realize the control of altitude and speed.And then the guidance methods are given.Simulation results and their a-nalysis show preliminarily that the TAEM nominal trajectory is designed flexibly and well suited to tracking the nom-inal trajectory.
