Summary
A ground vibration test can be used to obtain information about structural dynamics that is important for flutter analysis. Traditionally, this information-such as natural frequencies of modes-is used to update analytical models used to predict flutter speeds. The ground vibration test can also be used to obtain uncertainty models, such as natural frequencies and their associated variations, that can update analytical models for the purpose of predicting robust flutter speeds. Analyzing test data using the norm, rather that the traditional 2-norm, is shown to lead to a minimum-size uncertainty description and, consequently, a least-conservative robust flutter speed.
