Problems of System Identification in Flight Vibration Testing

Abstract

The accuracy of modal data analysis was studied for two tests with up to 8 different methods of analysis. It was found that the state of the art is poor and insufficient to deal with critical flutter cases. Improvements are possible and should be sponsored.
