A tiltwing aircraft is similar in concept to a tiltrotor design. Whereas a tilt rotor rotates the propeller from axial to dorsal, a tiltwing rotates the entire wing, not just the nacelles or prop and shaft. They are typically fully capable of VTOL operations.
An advantage of tilt wing over tilt rotor is that when the rotors tilt up, the wings rotate so that they do not block the downward air. On the V-22 this reduces lift by 10% in purely vertical flight, but the fixed wings offer better angles of attack for short takeoffs and landings.[1]
