Abstract: A wing pivot apparatus for rotating a wing between a flight orientation and a stowed orientation relative to a fuselage of a tiltrotor aircraft. The apparatus includes a stow ring that is rotatably mounted to the fuselage. Forward and aft wing attach assemblies are coupled respectively to forward and aft spars of the wing and are coupled to the stow ring. Forward and aft connecting assemblies are coupled respectively between the forward and aft wing attach assemblies and the stow ring and are selectively securable respectively to first and second fore-aft beams of the fuselage. A plurality of lock assemblies selectively secures the connecting assemblies to the fore-aft beams of the fuselage when the wing is in the flight orientation. An actuator coupled to the fuselage is operable to reversibly rotate the wing between the flight orientation and the stowed orientation.

Abstract: A wing pivot apparatus for rotating a wing between a flight orientation and a stowed orientation relative to a fuselage of a tiltrotor aircraft. The apparatus includes a guide ring that is fixably coupled to the fuselage. Forward and aft wing attach assemblies are coupled respectively to forward and aft spars of the wing and are moveably supported by the guide ring. Forward and aft wing support fittings are coupled respectively to the forward and aft spars of the wing and are selectively securable respectively to first and second fore-aft beams of the fuselage. A plurality of lock assemblies selectively secures the wing support fittings to the fore-aft beams of the fuselage when the wing is in the flight orientation. An actuator coupled to the fuselage is operable to reversibly rotate the wing between the flight orientation and the stowed orientation.
