翼吊式发动机安装设计综述

发动机安装是飞机总体设计中必须考虑的因素，发动机吊挂作为将发动机动力传递给飞机的结构部件，其安装设计非常重要。针对翼吊飞机的特点，介绍了发动机安装位置对飞机特性的影响，阐述了几种不同吊挂形式以及吊挂与机翼、吊挂与发动机连接形式的优缺点。分析表明：盒形梁式吊挂盒段结构、吊挂与机翼静定连接形式、吊挂与发动机主体连接形式是发动机吊挂结构的首选方案。

A Review on the Installation Design of Wing-Mounted Engine

Engine installation is one of factors that must be considered in the aircraft design. Pylon is a structure which passes the engine power to the aircraft. Its installation design is very important. According to the charac teristics of wing-mounted engine, the influence of engine installation on the performance of aircraft is analyzed. Advantages and disadvantages of several pylon structures, and some forms of connection between pylon and wing, pylon and engine are introduced. The analysis shows that the box beam structure of pylon with the staff cally determinate connection between pylon and wing, pylon and engine is the preferred solution for pylon de- sign.
