We have been working on ground vibration testing the DarkAero 1 prototype. The objective of this effort is to characterize the vibration mode shapes, natural frequencies, and damping of the airframe. This will help us build a model of the aircraft to predict flutter speeds and ultimately the Vne or never exceed speed of the airplane.
