中文摘要：

开展了高超声速飞行器机身／超燃冲压发动机一体化设计方法的研究。以多目标遗传算法为优化方法，采用一维流动模型计算性能指标，对机身下壁面前体和后体型线进行了优化设计，得到了Pareto最优前沿面。计算结果表明该方法可大大提高机身／发动机的匹配水平，获得高性能的设计方案。该方法可进一步推广应用于包含更加精确的流动模型的优化设计当中。

英文摘要：

This paper presents the airframe/scramjet integrated design method of hypersonic vehicle, in which we design lower surface configuration of airframe and get the Pareto front side through using one-dimensional flow formula to compute performance objectives, and adopting multi-objective genetic algorithms as the optimization method. The calculation results show that this design method can improve the matching level of airframe/scramjet integration greatly, and can give us a design project of high performance. As a method, it can be applied in the optimization design with more accurate flow model.
