摘要
航空发动机的转动频率对其工作效率、安全性和可靠性等都具有重要影响,过快和过慢的数值都会影响发动机的运行状态,我国发动机测试技术起步比较晚,因此对发动机参数的测量显得尤为重要,设计了一种基于电涡流原理的高温转速传感器,符合高温状态下对发动机转速的测量,可有效地监测发动机运行效率。
The rotational frequency of aero-engine has an important influence on its working efficiency,safety and reliability,too fast and too slow numercical value will affect the running state of engine.Test technology of engine of our country started relatively late,so the measurement of engine parameters is particularly important.A hightemperature rotating speed sensor based on eddy current principle is designed,which meets the requierment of engine rotating speed mesaruement under high temperature condition,it can effectively monitor efficiency of engine operation.
