中文摘要:民用飞机后压力框与机身连接的结构方案主要有两种,详细介绍了两种连接方案的结构构型以及各方案的优缺点,并从后压力框外形曲面的设计、结构的选材、质量、装配和维护空间以及系统在后压力框站位的通路等方面对两种连接方案进行分析和总结,为民用飞机后压力框与机身的连接设计提供参考。
英文摘要:There are mainly two structural connection schemes for connection of aft pressure bulkhead and fuselage on civil aircraft. This paper introduces the structure configuration, advantages and disadvantages of the two connection schemes in detail. The two connection schemes are analyzed and summarized from aspect of the design of OML(outer mold line) surface of the aft pressure bulkhead, the material selection of structure, the weight, the assembly and maintenance space, and the path of system layout planning on pressure bulkhead station. This paper can provide reference for design of the connection between aft pressure bulkhead and fuselage of civil aircraft.
