Flutter Prediction from Flight Flutter Test Data

摘要

The Conclusions section of the original paper stated that the best flutter predictions for the Sim-2 model were obtained from the application of the damping fit method. This conclusion must be altered now that results from the NGM are available for this model. The damping fit method still delivers the best overall accuracy; however, at high subcritical airspeeds, the best flutter predictions are obtained from the Nissim and Gilyard technique. In a real flutter test, most of the test points are generally concentrated at the higher subcritical conditions, exactly the flight regime where NGM works best.
