A tiltwing aircraft is similar to the tiltrotor V-22 Osprey. Whereas a tilt rotor rotates the prop from axial to dorsal, a tiltwing rotates the entire wing, not just the nacelles (as in the V-22) or prop and shaft. They are typically fully capable of VTOL operations.
The Canadair CL-84 Dynavert was a successful tiltwing design that never went into production.
