摘　　要：针对垂直起降可重复使用运载火箭上面级入轨,一级垂直返回发射场的发射任务,基于两级直接入轨运载火箭设计了入轨和回收过程不同飞行阶段的飞行程序,建立了入轨回收一体化优化参数模型,使用二分法获得最优值区间范围后,使用序列二次规划算法进一步寻优。优化结果表明,所提出的参数控制模型能保证一级回收,满足约束条件的同时实现火箭运载能力最大化。To complete the launch task of the vertical take-off and vertical landing(VTVL)reusable rocket which delivers the upper stage to target orbit and makes the first stage return to the launch site vertically.The flight procedures for injection and recovery in different flight stages are designed based on the two-stage direct-to-orbit rocket.Additionally,an integrated optimization parameter model for orbit entry and recovery is established.The optimal value range of parameters is obtained using dichotomy,the successive quadratic programming algorithm is used for further optimization.The optimization results demonstrate that the proposed parameter control model can maximize rocket carrying capacity while ensuring compliance with first-stage recovery constraints.
