摘　　要：针对垂直起降重复使用运载火箭总体设计多约束耦合问题,通过分析箭体构型、动力类型方案及动力布局类型,提出了优选两级单芯级构型、液氧甲烷动力和液氧煤油动力以及优选中小发动机多机并联方案,并优选5、7、9机并联动力布局。采用齐奥科夫斯基公式,对垂直起降重复使用运载火箭的运载能力进行估算,并以一二级间比为优化变量,进行初步总体优化,得到在不同箭体直径、动力类型和动力布局下的基础运载能力,结合长细比分析得出两级单芯级、奇数台发动机并联的垂直起降重复使用运载火箭总体方案。According to the multiple constraint coupling problem of conceptual vertical launch and landing reusable rockets,the composition configuration was analyzed by studying the configuration,the propellants and the propellant configuration.A preferred solution was proposed which was a two-stage single cored configuration,with hydrogen/oxygen and Lox/methane propellants,and multiple small or medium thrust engines.Moreover,the 5/7/9 parallel engines were selected as the optimal configurations.The launch and transportation capacity were estimated using Zioukovsky formula.In addition,the launch and transportation capacity were optimized,with first and second stage ratio an optimization variable,which yielded the basic launch and transportation capacity for variant diameter of rocket,propellants,and propellant configurations.By considering the slenderness ration,the fea-sible conceptual design of two-stage single cored,odd parallel engines vertical launch and landing reusable rockets were yielded.
