民用飞机后机身与尾段的对接往往选择球面框(后压力隔框)位置，球面框是机身气密线的末端，该处的对接设计需要从传力、重量、成本、装配、维修、排水等多方面进行考虑，是民用飞机机体结构设计中非常重要的一个环节。针对民用飞机中后机身与尾段的连接特点，从传力等考虑要素入手，介绍了目前国际上典型机型的成熟方案，并进行方案优缺点分析、比较和总结，为我国民用飞机结构设计提供借鉴。
民用飛機後機身與尾段的對接往往選擇毬麵框(後壓力隔框)位置，毬麵框是機身氣密線的末耑，該處的對接設計需要從傳力、重量、成本、裝配、維脩、排水等多方麵進行攷慮，是民用飛機機體結構設計中非常重要的一箇環節。針對民用飛機中後機身與尾段的連接特點，從傳力等攷慮要素入手，介紹瞭目前國際上典型機型的成熟方案，併進行方案優缺點分析、比較和總結，為我國民用飛機結構設計提供藉鑒。

The joint between after fuselage and the tail for commercial aircraft locates on dome ( after pressure bulkhead) generally. Dome is the end of the pressure line. The joint structure design should take load path, weight, cost, assembly and drainage into account, is one of the most important content during fuselage design. Ac-cording to the properties of joint between after fuselage and the tail, commencing with load transfer consideration, the mature concepts of representative aircraft are introduced, and the concept analysis, comparison and summary are provided. The conclusion could provide a technology support for civil aircraft structure design.
