在分析国外滑跃式高超音速巡航飞行器的发展现状基础上,提出了高超音速巡航飞行器的概念设计,对滑跃式高超音速巡航飞行器总体方案提出了设想。选择乘波构型建立了滑跃式高超音速巡航飞行器的气动布局,采用Euler方程数值解法Dahlem-Buck公式和切楔法对气动布局的亚、跨、超、高超音速气动特性进行了计算分析。由结果可见,建立的气动布局可满足总体方案设想中飞行任务要求。对滑跃式高超音速巡航飞行器的动力技术进行了初步研究,分析了采用火箭基组合循环发动机(RBCC)方案所需的燃料消耗。由初步分析计算结果可见,对于Ma≈10的滑跃式高超音速巡航飞行器,采用RBCC作为推进系统,可满足总体方案的技术要求。

Preliminary design for soaring hypersonic cruise vehicle

On the basis of analyzing development status of soaring hypersonic cruise vehicle abroad,the conceptual design of hypersonic cruise vehicle was put forward,and system scheme of soaring hypersonic cruise vehicle was given.The aerodynamic layout of soaring hypersonic cruise vehicle was built by using waverider configuration.The subsonic,transonic,supersonic and hypersonic aerodynamic performances of aerodynamic layout were analyzed and calculated by means of Euler equation numerical calculation method,Dahlem-Buck formula and wedge cutting method.The results show that the aerodynamic layout can meet the aerodynamic requirements.Finally dynamic technology of soaring hypersonic cruise vehicle was preliminarily investigated.The fuel consumption of rocket based combined cycle(RBCC) for the soaring hypersonic cruise vehicle was analyzed.The results show that RBCC which is used as propulsion system for the soaring hypersonic cruise vehicle with Mach number 10 can meet technique demands of system scheme.
