Track 1: Aircraft Ground Vibration (GVT) Test Set-up

Thursday, 30 September 2021 14:00 - 14:30

The Ground Vibration Testing (GVT) of the aircraft while it is on the ground is critical not only for the comfort of the pilot and passengers but also for the safety and structural integrity of the aircraft. Large scale modal test on full aircraft or rotorcraft helps to identify natural frequencies, damping, and mode shapes. The test data is used to adjust and validate dynamic FEA models used for flutter prediction, and once verified and updated this model can be used to understand the influence of configuration changes and modifications on the flutter flight envelope and other aerodynamic load related problems. Today’s presentation will go through many of the practical testing aspects of GVT.”
