Uncertainty Propagation in Flutter Analysis

Full text not available from this repository.


Since simplifications are introduced in the theoretical formation of the models on one hand, and the measuring accuracy is limited in the experiment on the other, models and their parameters may include uncertainties, making it difficult to determine the dynamic stability boundaries. For the robust flutter analysis, it is necessary to propagate the effects of identified uncertainties towards aeroelastic stability of the aircraft to cover the uncertain-butbounded parameter space. Robust stability is guaranteed when the uncertainties cannot destabilize the system.
