Kurzfassung
The Swiss company Pilatus Aircraft Ltd. is developing the new trainer aircraft PC-21. Before first flight, ground vibration tests were performed on the prototype of this aircraft by DLR. The main objective of the tests were to provide a reliable data base for validating the mathematical model of the aircraft for aeroelastic analyses. The aircraft was investigated in three configurations with full and empty tanks and with additional external tanks. Both phase resonance and phase separation methods were applied. The measurements provided the normal modes and the respective modal parameters in the frequency range up to 80 Hz including nonlinearity investigations.
