Abstract
For the continuously-varying dynamic pressure flutter test data in the high-speed wind tunnel; this paper analyzes the strengths and weaknesses of the data Processing Method in this field. The data selection and stacking mode is improved. A Butterworth IIR digital filter is used for digital filtering. The power spectral density function is computed by Fourier transform of the autocorrelation function. A pick-hold method is used to predict the flutter critical point. It is indicated that our method features high accuracy and efficiency by theoretical analysis and wind tunnel flutter test.
