Abstract:Flutter flight test is highly risky,and it is a complex experiment with multidisciplinary crossover. Its real-time monitoring and analysis is extremely important. Based on the domestic civil aircraft flutter test,this paper designs and develops a real-time monitoring and analysis system using the Measurement Studio platform. The system integrates algorithms such as half-bandwidth method,fast Fourier transform and wavelet transform to realize timefrequency domain analysis and damping calculation of flutter data. In addition,the system records flutter data in real-time with text format. At the same time,the system completes the real-time display of the analysis results with multithreading and Data Binding model,which can provide technical support for the safe flight test of domestic civil aircraft.
Keywords:flutter  Measurement Studio  real-time analysis  DataBinding
