Ground Vibration Testing (GVT) — Finite Element VTOL, eVTOL & UAM

Airworthiness & GVT Certification

Ground Vibration Testing (GVT) is a critical FAA & EASA milestone, yielding experimental vibration data to validate and refine structural dynamic models for flutter prediction and safety-critical flight tests.

Performed late in development under tight schedules, GVT must be swift yet thorough. Modern lightweight structures and VTOL architectures introduce dynamic uncertainties, demanding precise modal testing to ensure compliance and safety for new UAM concepts.

▶ Calibrate FE models for flutter predictions
▶ Extract modal frequencies, damping, mode shapes
▶ Perform structural coupling with control systems
▶ Reduce risk of flight-test flutter

Aeroservoelasticity (ASE) integrates flexible structures, aerodynamic loads, and control laws. ASE models calibrated during GVT underpin accurate flutter analysis across the flight envelope.
