摘　　要：针对空投变掠翼滑翔炸弹攻击弹道优化和姿态控制问题开展了研究。首先,建立了考虑变体附加力和力矩的动力学模型,以后掠角和俯仰舵偏角为控制变量,构建了弹道优化最优控制模型;然后,采用hp自适应伪谱法将其转化为非线性规划问题,仿真计算得到了变掠翼滑翔炸弹的最大射程和最小射程,分析了投放高度对炸弹可达域的影响。研究结果表明,采用的方法能快速得到满足精度的计算结果,变掠翼滑翔炸弹的可达域随投放高度的增加而增加,所得结果可为滑翔炸弹的作战使用提供参考。The trajectory optimization and attitude control of air-dropped variable-sweep wing glide bombs are investigated. Firstly, the dynamic model considering the additional force and moment of the variant was established, and the optimal control model of trajectory optimization was constructed by taking the sweep angle and the pitching rudder angle as the control variables. Then, the hp adaptive pseudospectral method was employed to transform the model into a nonlinear programming problem. The maximum and minimum range trajectory of air-dropped variable-sweep wing glide bombs was obtained, and the influence of altitude on the reachable domain was analyzed. The research results show that the algorithm gives fast results that satisfy the accuracy and the reachable domain of the bomb increases with the initial altitude. The results obtained can provide reference for the operational use of variable-sweep wing glide bombs.
