Accelerometer is an instrument for measuring the acceleration of the carrier line. The accelerometer is one of the first aircraft instruments to be used for measuring aircraft overload. Accelerometer consists of test quality (also known as sensitive mass), support, potentiometer, spring, damper and shell. Accelerometer is commonly used to monitor engine failures and fatigue damage of aircraft structures.
In the flight control system, accelerometer is an important dynamic characteristic correction element.In inertial navigation system, the high precision accelerometer is one of the most basic sensitive components.The accelerometer in different use situations is different in performance. The high precision inertial navigation system requires the accelerometer to have a resolution of 0.001g, but the range is not large. An accelerometer that measures an aircraft’s overload may require a range of 10g, while the accuracy is not high.
