T-Wing project will develop an innovative composite wing for the next generation Civil Tiltrotor which will contribute to a substantial increase in performance in terms of aerodynamic efficiency and weight reduction through the use of innovative design techniques and advanced production technologies. The FLAP can rotate of ≈90 degree in order to reduce as much as practical the area of impingement between wing and rotor downwash when the vehicle is transitioning to/from or is in the hover.
