摘要

通过对风扇/压气机叶片外物损伤及其失效特点的深入分析

认为叶片外物损伤容限设计的本质是考虑外物损伤影响的叶片振动应力设计.通过对国内外发动机设计规范和标准的分析和回顾

将外物损伤容限设计准则的发展分为3个阶段:①50年代初-60年代末

以外物损伤(FOD)的预防和维护为主;②70年代初-90年代末

等效为应力集中系数Kt≤3的缺口容限设计;③2000年以来

FOD的概率容限设计.最后对我国外物损伤容限设计的研究方向提出了建议.

Abstract

Through the analysis of foreign object damage(FOD) and failure characteristic of fan and compressor airfoils

it was concluded that vibratory stress design and control of airfoils according to reduced material allowable due to FOD is the fundamental feature of FOD tolerance design.Then

by the analysis and review of specifications and standards for aeroengine

the development process of FOD tolerance design criteria was divided into three phases.In the first phase(1950s'-1960s')

FOD related failures were mainly regarded as prevention and maintenance problems.During the second phase(1970s'-1990s')

FOD tolerance design was equivalent to withstand to a notch with a stress concentration factor(Kt) not exceeding 3.0 at the most critical locations of flow path components.Since 2000

a probabilistic design criteria has being in its development phase and has obtained great progress.Finally

some advice was put forward on the research directions of FOD tolerance design technology in China.
