| 摘 要： | 探讨了航空发动机气路颗粒静电监测技术的工作原理和技术特点。为进行该技术的可行性研究搭建了模拟实验台，利用电晕模拟了气路故障发生时尾气中不同大小的带电颗粒，使用自制的探针式静电传感器对运动带电颗粒进行监测，信号调理器将感应电荷放大并转换为对应的电压，结果显示：①静电传感器能够监测到运动带电颗粒；②感应电压幅值与颗粒大小有关；③感应电压波形与颗粒性质有关；④大量小颗粒和单个大颗粒混合物的感应电压表现出两者各自的特征。

| Abstract: | The principle and characteristics of aircraft engine gas path debris monitoring technology is presented. Simulated experiment facilities are developed to prove the feasibility of this technology. Charged particles with different diameters are generated as simulated fault debris in the gas path of an aircraft engine. A probe type sensor is used to monitor the induced signal of the fast moving charged particles. A signal conditioner unit amplifies the induced charge signal and then converts the induced charge... |
