摘要: 采用正交试验设计方法生成初始数据库,建立二次多项式响应面近似模型,以最大巡航距离为设计目标,机体/推进一体化外形参数和巡航弹道参数为设计变量,对高超声速飞行器进行了多约束多学科的并行子空间优化设计.优化设计获得了多学科融合条件下的最优化外形和弹道参数,可作为飞行器进一步详细设计的参考方案.Abstract: By employing orthogonal experiment design method to build up an initial database and approximate response surface model of quadric polynomial,this paper presented a concurrent subspace optimization process of hypersonic cruise vehicle(HCV) for airframe/scramjet integrated shape parameters and trajectory parameters based on multi-restricted and multi-disciplinary conditions.Through the optimization process,the optimal shape and trajectory parameters on multi-disciplinary synergetic conditions were acquired,providing a reference scheme of HCV for further detailed design.
