Abstract:

The article deals with an overview of the accelerometers which are used to measure the vibration of aircraft engines and linear acceleration in the inertial navigation, deficiencies of vibration sensors are revealed, presented a dual channel piezoelectric accelerometer with improved performance that allows the simultaneous measurement of vibration and g-load is presented and the modernization of modern aircraft engine vibration sensors including GEnx is under consideration. 5 ill.
