摘　　要：航空发动机在经历过大修或特定修理后,在出厂前需进行的地面试车环节是保证以及衡量发动机当次进厂维修质量的关键步骤。发动机在试车台进行测试时,最能直观反映发动机性能的两个参数为发动机排气温度裕度(EGT margin)和发动机推力。本文对现有的推力测试技术原理与优缺点进行一定的分析与总结,从而为国内航空发动机试车台的设计、安装与维护提供参考。In case an aeroengine has undergone overhaul or specific repair,the ground test run before engine's release is a key procedure to ensure and verify the in-house maintenance quality of the engine.When the engine is tested in the test cell,two parameters will most intuitively reflect the engine performance:exhaust gas temperature margin(EGT margin)and engine thrust.In this paper,the technical principles,advantages and disadvantages of the current thrust measurement technique are analyzed and summarized,so as to provide reference for design,installation and maintenance of domestic aeroengine test cell.
