Abstract : The power spectral techniques of generalized harmonic analysis were applied to determine the phase and amplitude of the transfer function between the vertical component of turbulence and the resultant pitch rate of a small swept wing jet fighter. The power spectrum analysis was based on actual flight test data. In addition, the amplitude and phase of the aircraft's transfer function are determined theoretically by two different methods and compared with the results of the power spectrum analysis. It was established that the power spectrum method, as applied to random turbulence, can be used to determine an aircraft's response to this random input on a continuous basis and that power spectrum techniques have considerable potential value in the study of aircraft gust loading.
