Unmanned experimental aircraft fitted with highly flexible wing shows flutter can be actively suppressed, potentially saving weight and drag.
Data collected in latest wind-tunnel tests will help improve simulation models and develop flight control laws for NASA’s supersonic X-plane.
Speedy V-280 tiltrotor, predicting flutter in real time, airborne wind power, certifying ScanEagle3, and landing UAVs on ships.
Will one configuration come to dominate the emerging urban air transport market?
Mutlirotors, tiltwings, tiltrotor, ducted fans—there is no shortage of designs for electric VTOL air taxis, but which are practical and which will dominate the market?
NASA’s Gulfstream III testbeds gather data on landing-gear treatments and trailing-edge flap designs that promise to reduce aircraft noise.
