摘　　要：针对具有大落角和末速限制的制导火箭弹的发动机技术要求优化问题,提出了一种基于高斯伪谱法的总体优化设计方法。将落角作为终端约束,取目标函数为最大化末速,进行了方案弹道优化。通过数值仿真,给出了在满足落角约束条件下最大末速随射程的变化规律。可为制导火箭弹的总体设计提供一定的参考。Based on Gauss pseudospectral method,system design and optimization for guided rockets with impact-angle and terminal speed constraints was proposed.The trajectory optimization plan was established in which the target function was chosen as the speed at the impact point,and the impact angle as a terminal constraint.Numerical simulations were performed and the results show the speed profile of the guided rocket at impact point with respect to range.It is useful for guided rocket systems design in practice.
