The first BelugaXL has passed the Ground Vibration Test (GVT), a requirement for certification of the aircraft that paves the way towards its maiden flight in summer 2018.
The objective of this test is to measure the dynamic behaviour of the aircraft and confirm theoretical models of various flight conditions, such as manoeuvring, flying in gusty conditions and landing. The test data also helps clear the aircraft’s flight enveloppe.
The GVT of the BelugaXL was performed by ONERA in collaboration with DLR over eight testing days using several hundreds of external accelerometers while the aircraft was stimulated by external shakers or seismic exciters.
