本文主要研究内容
作者（2019）在《新型内转式乘波前体-进气道一体化设计方法（英文）》一文中研究指出：目的:针对高超声速飞行过程中机体前缘和进气道之间相互影响的问题,本文从头部进气的角度出发,利用内转式进气道高总压恢复系数和高压缩效率的特性,探索前体与进气道的一体化设计。创新点:1.提出一种内转式轴对称基准流场的构建方法,并设计生成内转式进气道;2.设计内转式乘波前体/进气道一体化构型,并提出将进气道进口型线划分为前体前缘型线(FCC)和进气道唇口型线(LCC)。方法:1.构建内转式轴对称基准流场(图9);2.在基准流场中生成内转式进气道并设计构造进气道外表面(图13);3.通过仿真模拟,验证所提方法及原理的正确性和有效性(图15～20)。结论:1.基于特征线理论,设计并求解内转式乘波前体/进气道轴对称基准流模型(IARFM),同时设计并生成了内转式进气道和外壁面;提出将进气道进口型线划分为前体前缘型线(FCC)和进气道唇口型线(LCC)。2.提出了内转式乘波前体/进气道(ITWF)的一体化设计方法,并通过对无粘数值模拟结果与理论设计值的比较,验证了设计方法的正确性和有效性。3.经过分析可知,激波形状和位置的数值模拟结果与基准流模型吻合较好。这些结果验证了无粘流设计条件下的一体化设计过程的正确性,且该一体化结构具有较高的总压恢复系数和气流捕获效率。
