The control room for the remotely piloted X-56A has a feature that most do not – the pilot and co-pilot are in the front of the room, seen at left. The X-56A team has successfully suppressed flutter, which is a potentially destructive oscillation, with a classical and a modern controller. The controllers are essentially mathematical ways of directing the aircraft.

Long, thin, high-aspect-ratio wings are considered crucial to the design of future long-range aircraft, including fuel-efficient airliners and cargo transports. Unlike the short, stiff wings found on most aircraft today, slender, flexible airfoils are susceptible to uncontrollable vibrations, known as flutter, and may be stressed by bending forces from wind gusts and atmospheric turbulence. To improve ride quality, efficiency, safety, and the long-term health of flexible aircraft structures, NASA is using the X-56A Multi-Utility Technology Testbed (MUTT) to investigate key technologies for active flutter suppression and gust-load alleviation.
