民用运输机吊挂设计强度要求研究

Strength Requirement Research of Civil Transport Pylon Design

论述了民用运输机吊挂设计强度要求,并重点阐述了以下几个方面:吊挂初步设计载荷、FBO载荷计算要求、发动机非包容性转子损坏下的适航符合性思路及离散源损伤容限剩余强度评估要求。在这几部分的阐述中,有具体的设计数据及案例,对设计工作有很好的指导作用。

This article dissertate the strength requirements research of civil transport pylon design, especially on the following aspects： pylon preliminary design loads, FBO loads calculation requirements, mean of compliance of uncontained engine rotor failure and residual strength evaluation requirement of discrete source damage tolerance.
