运输机机身尾段对接设计研究

摘要

对国内外运输类飞机机身尾段和后段的对接设计进行了分析总结，归纳出了3种典型对接形式。对各种对接形式进行了分析，从结构传力、工艺性、维修性和重量等方面阐述了各种对接形式的优缺点，可为运输类飞机机身设计提供借鉴。%The abutting joint design between fuselage tailcone and rear fuselage of several domestic and foreign transport aircraft are analyzed. And three typical abutting joint forms are concluded. With the comparison of these structures, the advantages and disadvantages of al the abutting joint forms are demonstrated on the aspect of load delivering, manufacturing, maintainability and weight. It can provide reference to the design of transport aircraft.
