A Fatigue Loading Monitoring Method Based on Strain Data Analysis in Primary Flight Control System Fatigue Tests

Sun Xiang

Abstract

The dynamic strain measurement and test loading monitoring problems in primary flight control system fatigue tests are discussed.A fatigue test loading monitoring method based on train measuring data analysis and its application to primary flight control system fatigue tests is presented.The monitoring results from flight control system fatigue tests show that this method based on strain data anlysis is practicable and effective for several test modes in aileron,elevator and rudder control system tests.
