THE DESIGN OF MICRO-DIFFERENTIAL PRESSURE SENSOR--THE SOLUTION FOR FAILURE OF AIRCRAFT ENGINE DUE TO NON-OXYGEN GAS
微压差压力传感器的设计——解决航空发动机吸入无氧气体造成工作异常的方法

Due to the influence of the exhaust gas produced by airborne weapons on engine's operational parameter,a micro-differential pressure sensor is developed to measure the signal when the pressure in the air compressor falls suddenly.The system of antisurge can open in time to prevent the engine surge or stop.This paper discusses the sensor structure,the principle of work,the design principle and the main part parameter design method.And the test results show that the design requirement is satisfied.
