Abstract : Based on the results of ground vibration measurements carried out on the aircraft F-104G, analytical investigations to the question of orthogonality of the natural modes of aircraft are performed. With the theoretical mass distribution and the measured natural mode amplitudes the complete matrix of the generalized masses is calculated. Guided by these results, detailed considerations with respect to the orthogonality of the measured natural modes and the accuracy of the measured generalized masses are presented. (Author)
