民用飞机垂尾和后机身连接结构设计与研究

摘要

民用飞机垂尾是飞机结构的主要受力部段，垂尾和后机身的连接处受力复杂，是飞机设计的难点之一。参考国外成熟机型垂尾和后机身连接方案，分别从重量、制造、装配、损伤容限、维修性等方面详细分析了垂尾和后机身多种连接方案的优缺点，研究并设计出一种改进的垂尾和后机身连接方案。%Vertical tail for civil aircraft is a main load component of aircraft structure. The load conditions of joint structure between vertical tail and rear fuselage are complex,and it’ s difficult to design. This paper takes several advanced aircraft as example, Compared with several schemes of vertical tail and rear fuselage joint structure in weight,manufacture,assembly,damage tolerance,maintenance . Finally, a improved joint structure is designed.
