摘　　要：为满足航空发动机压气机叶片振动监测的高温要求,设计了一种能够耐650℃高温的新型光纤式叶尖定时传感器.采用金属保护结构及涂覆高温胶技术提高了传感器探头的耐温性能.在此基础上,设计了一种模拟叶尖定时传感器高温工作环境的验证装置,对改进后的光纤式叶尖定时传感器进行了高温试验.试验结果表明,该型传感器能够耐受650℃工作环境,满足航空发动机高压压气机叶片振动参数监测的要求.To meet the high temperature requirements for the vibration monitoring of aero-engine com-pressor blades, a new optical fiber tip-timing sensor which can resist 650 ℃ high temperature was de-signed. The application of metal protective structure and high-temperature plastic coating technology has improved the high temperature resistant capability of the sensor probe. Meanwhile, a testing device that can simulate the high temperature working environment of tip-timing sensors was designed, and a high temperature experiment was carried out to verify the working capability of the sensor. Results show that this type of sensor can resist the high temperature of 650 ℃, meeting the requirements to measure the blade vibration parameters of the aero-engine high-pressure compressor.
