Flutter testing aircraft
WebFlutter analysis ensures the aircraft is safe and free from flutter at all points in the flight envelope. Flight flutter tests must be performed to demonstrate the accuracy of the analysis and prove the airplane is safe to operate. Flutter is critically dependent upon airspeed because the dynamic pressure in the airstream provides the energy ...
