The tiltrotor test rig (TTR) development team at NASA Ames Research Center was honored today with a 2013 NASA Group Achievement Award. Team members include personnel from NASA Ames, Bell Helicopter and Triumph Aerospace Systems. The TTR is a joint project among NASA, the U.S. Army and U.S. Air Force to develop a new large-scale system that can test prop-rotors up to 26 feet in diameter at speeds up to 300 knots, allowing for advanced research on tiltrotors and other rotorcraft concepts.
