Ground Vibration Test

Ground Vibration Tests ( GVT) are needed on all new aircraft types or after major modifications of existing models. Its first objective is to verify models used for the calculation and prediction of the dynamic behavior of the structure. Flutter prediction is the first concern for the safety and certification of the aeroelastic behavior of an aircraft, but other dynamic aspects, such as sustained vibration due to engine unbalance, need verification. The main target of the tests is to identify the different modes of vibration of the aircraft, as well as their frequency, damping and scaling characteristics. It is also used to detect structural flaws and troubleshoot flight control dynamic problems. For more information please contact us at ariefo@ indonesian-aerospace.com+ 62 8157006547.
