FEATURES OF SIMULATING THE FORCE ACTIONS FROM A DAMAGED ENGINE AT GROUND VIBRATION TESTS OF AN AIRPLANE
ABSTRAKT
In this study, the features of the experimental methodology, variants of the implementation of force actions, assessment of the possibility of superposition of vibrations, and the experimental hardware were considered. A simulation of the inertial forces from an engine imbalanced due to blade loss during ground vibration tests (GVTs) was performed. The parameters of the forced airplane oscillations in the case of a non-rotating engine rotor were measured. Some results are presented. The first domestic experience of tests of full-scale airplanes with imbalance simulation has confirmed the possibility conducting regular GVTs.
