摘要

介绍了航空发动机燃烧室温度场测量所用的燃气取样器和燃气分析系统，并对系统简化所引起的误差进行了分析.阐述了“点”燃烧温度的计算方法以及利用“点”燃烧效率、油气比和燃烧温度计算总平均值的方法.数据显示利用热电偶测量温度获得的燃烧效率比燃气分析法燃烧效率约低4%，在燃气温度约为1500℃时，热电偶测得的燃气平均温度比燃气分析法平均温度低55℃左右，同时表明燃气分析方法在测量航空发动机燃烧室温度场具有可测温度高、影响因素少、数据准确的优势.

Abstract

Sampler and gas analysis system were introduced for temperature field of aeroengine combustor

and error was analyzed as a result of gas system simplification. Method of computing combustion temperature was expounded

the average of combustion efficiency and combustion temperature and fuel-air ratio was computed. The temperature field for combustor with five nozzles by gas analysis and thermocouple was analyzed

indicating that combustion efficiency by thermocouple was 4% less than that by gas analysis

and combustion temperature was 55℃ lower at 1500℃. Gas analysis was proven to be dominant in measuring high temperature gas from aeroengine combustor. High quality data can be gained by gas analysis

which is hardly influenced by environment.
