Advances in the state-of-the-art of aerodynamics, dynamics, and structures suggest that the flight envelope of the tilt-rotor VTOL vehicle XV-15 can be expanded by an improved rotor blade design. A description is presented of an intensive airfoil development study which has been conducted in connection with the conceived possibilities. State-of-the-art design techniques were used to produce the new sections, and a wind tunnel 'fly-off' between the best airfoils was held. Advanced technology airfoils demonstrated significant improvements in aerodynamic characteristics compared to existing XV-15 blade airfoils
