民用飞机货舱门与门框方案综述

Introduction of Cargo Door and Door Surrounding Structures of the Civil Aircraft

货舱门及其大开口补强设计是民用飞机机身结构设计的重点和难点之一。根据民机不同区域货舱的特点,介绍了机身上两种不同的货舱门与门框结构的设计思路,阐述了两者的典型结构形式,可供结构工程师在货舱门与门框结构方案选型提供一定的借鉴意义。

The cargo door and door surrounding structures design is one of the key points and difficulties in the design of the fuselage structures of civil aircraft. According to the characteristics of the cargo compartments in different areas of the civil aircraft, the design ideas of two different cargo door and door surrounding structures on the fuselage are introduced. The typical structural forms of the two are described, which provides structure engineers reference and guidance in the selection of cargo door and door surrounding structures design.
