MODEL PARAMETER ESTIMATIONS OF THE MULTI-CHANNEL TURBULENCE RESPONSE FROM FLUTTER FLIGHT TESTS BASED ON AUTOREGRESSIVE SPECTRA

Model parameter estimations of the multi-channel turbulence response from flutter flight tests based on autoregressive spectra

Signal processing of flutter flight test data enables verification of aircraft flutter design, and the signal from a flutter flight test excited by atmospheric turbulence is a particularly important form of the flutter test.Owing to the randomness of atmospheric turbulence excitation, multi-channel analysis of turbulence responses at various positi
