摘　　要：与常规飞机和一次性运载火箭不同,重复使用飞行器是航空、航天技术的高度融合,具有双层式结构,内层贮箱与外层飞行器机身之间的连接对飞行器至关重要。针对某重复使用飞行器,提出了静定结构和静不定结构两种连接方案,并采用有限元分析的方法进行了静力分析,通过比较和分析得知:静不定结构连接方案更加合理。Different from conventional aircraft and expendable launch vehicle, the reusable launch vehicle which has doubleshell structure, is the conjunct of aviation and space technology, the joint between inner tank and outer vehicle airframe is crucial. In this paper, two kinds of joint scheme were put forward which are statically determinate structure and statically indeterminate structure, and the finite element analysis method was used for the static analysis. Through the comparison and analysis, the statically indeterminate structure joint scheme is more reasonable.
