摘　　要：针对水平起降、单级入轨的空天飞行器末端能量管理段(TerminalAreaEnergy Management,TAEM)的轨迹设计问题,分析了空天飞行器在TAEM段有别于传统再入式飞行器的独特气动特性,探索性地提出了空天飞行器需考虑的特殊约束条件,并在此基础上建立了面向空天飞行器TAEM段的新的轨迹设计模型。针对空天飞行器TAEM段轨迹设计的特殊问题,采用基于动压-高度剖面的设计方法,设计了满足约束条件的TAEM段的轨迹仿真算法,并进行标称状态轨迹仿真。仿真结果表明,所设计的轨迹能够满足空天飞行器TAEM段的任务需求和特殊约束条件。Aiming at the trajectory design problem of the terminal area energy management(TAEM)phase of horizontal take-off and landing,single-stage to orbit spacecraft,the unique aerodynamic characteristics of the aerospace vehicle in the TAEM phase are analyzed,which are different from traditional re-entry vehicles.Special constraints that need to be considered are proposed,and a new trajectory design model for the TAEM phase of the spacecraft is established.Aiming at the special problem of trajectory design,a design method based on dynamic pressure-altitude profile is adopted to design a trajectory simulation algorithm that meets the constraint conditions,and nominal state trajectory simulation is carried out.The simulation results show that the designed trajectory can meet the mission requirements and special constraints.
