| 摘 要： | 使用了高度和航向航程匹配求解推重比的算法,解决了一种无直接解析解的参考轨迹的求解问题.在数值仿真的基础上,简化了参考轨迹的求解,给出了推重比与高度和航向航程的关系,以及这些关系存在的原因.应用Monte Carlo仿真法对该方法求解的可行性进行了仿真验证,并基于一个类Apollo的参考轨迹,验证了算法对参数分布引起的状态不定具有鲁棒性.

| Abstract: | An algorithm to obtain a proper thrust-to-weight ratio set by matching given altitude and downrange is proposed in this paper,and the set is essential for solving a reference trajectory which has been proven that no one analytical solution exists hitherto.On the basis of numerical simulation,the solving process is simplified and the correlation between the thrust-to-weight ratio and the needed altitude and downrange span is given.Furthermore,a Monte Carlo simulation is also designated to verify the validati... |
