European researchers have used scaled aircraft demonstrators to test new concepts for lighter, larger-span wings intended to avert flutter problems. The ground vibration tests were conducted at a ...

Any time you change a flight control’s mass, it negatively affects the speed at which the flight control can flutter. The mass of a flight control can change due to drain holes getting plugged as well ...

In a collaboration between the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR, Göttingen, Germany) and the Technical University of Munich (TUM, Munich, Germany), researchers ...

The future of commercial aircraft will probably include long, thin, flexible wings that reduce weight and drag for extra efficiency and ride comfort. NASA and Lockheed Martin's Skunk Works division ...

From our very first flight lessons we were taught to check for “full and free correct movement” of flight controls. Every preflight, whether it is for a normal flight or a post-maintenance test flight ...
