民用航空发动机燃烧室试验技术分析与研究

Research on test technology of civil aero-engine combustor

近年来,我国的大型客机发动机研制正处于攻坚阶段,零部件试验和整机试验均在大量开展。为了更好地支撑我国民用航空发动机低污染燃烧室的研发工作,阐述了大涵道比涡扇航空发动机燃烧室的典型研发路径,并对单头部、多头部和全环燃烧室3个研发阶段的试验技术进行了重点分析,介绍了每一阶段的主要试验内容、试验过程、试验设备、测试技术、关键环节以及各阶段试验面临的共性问题;同时,在燃烧室试验压力与温度、测试技术、试验研究的丰富性与前瞻性等方面进行了国内外对比分析,总结了我国民机燃烧室试验技术的发展现状,可为国内相关单位在研发民机低污染燃烧室、建设试验器、提升测试能力和填补技术空白等方面提供借鉴。

In recent years,the engines for large commercial airplane are being developed closely,and the tests for main components and the whole engine are being conducted massively in China.For the purpose of supporting the development of low-emission combustors,the paper introduces the typical R&D path of a civil engine combustor,and mainly focuses on the test technologies of single cup,multiple cups and full annular combustors,in which the main test subjects,test process,instrumentation,key points and common issues have been summarized.At the same time,by making a comparison of test pressure/temperature,instrumentation,test abundance and perspectiveness between China and western countries and by summarizing of Chinese civil combustor test technology developments,the paper gives reference to the domestic researchers in the fields of low-emission combustor research,test facility construction,measurement enhancement and gap filling.
