Comprehensive evaluation for hypersonic vehicle trajectory optimization algorithm has good reference value on selecting optimal trajectory optimization algorithm.According to the features of hypersonic vehicle,trajectory was decomposed into ascent,cruise and descent stages;the performance evaluation indices of each stage and the typical methods of weighting for performance evaluation index were given respectively. Combining with the analysis theory of grey correlation degree,a comprehensive evaluation method of trajectory optimization algorithm was proposed. The calculation results show that the method can quantitatively evaluate trajectories produced by trajectory optimization methods and sort the alternative optimization methods by merits.%高超声速飞行器弹道优化算法的综合评估对选取最优的弹道优化算法具有重要的参考意义。根据高超声速飞行器的特性，将其弹道分解为上升段、巡航段及俯冲段三个阶段，分别给出了各阶段的性能评价指标和对各阶段性能评价指标赋权的典型方法，并结合灰色关联度分析理论提出了弹道优化算法的综合评估方法。评估实例表明，该方法能定量地对多种弹道优化方法所生成的弹道进行综合性能评估，并能对备选优化方法的优劣进行排序。
