Abstract

A ground vibration test was conducted with a 1:3 scaled Diana 2 glider model where the modal parameters were estimated using the accelerometers, gyroscopes and strain gauges integrated in the test aircraft and validated using externally attached calibrated accelerometers and commercial software. These modal parameters were then used to update a FEM model of the glider together with static load tests and component mass measurements. The goal for this updated and fitted FEM model is then to build an aeroelastic model for flexible aircraft flight dynamics simulator.
