Abstract: Systems and methods of operating a tiltrotor aircraft include providing the tiltrotor with a plurality of rotatable pylon assemblies. Each pylon assembly includes a rotor system having a plurality of rotor blades operatively coupled to a rotor mast and selectively rotatable in response to rotation of the rotor mast, a swashplate assembly operatively coupled to the plurality of rotor blades, a plurality of swashplate actuators operatively coupled to the swashplate assembly and selectively extendable and retractable to control the position and the orientation of the swashplate assembly, and a swashplate augmenting system. The swashplate augmenting system is selectively operable to cause axial translation of the swashplate actuators and swashplate assembly to augment the travel of the swashplate actuators in order to fold the plurality of rotor blades for operating the tiltrotor aircraft in an airplane forward flight mode.

Abstract: An apparatus for chordwise folding and locking of rotor systems includes a grip assembly and a harness disposed at least partially within and coupled to the grip assembly. A rotor blade is rotatably coupled to the grip assembly and the harness. The rotor blade has a radially extended orientation and a stowed orientation. A linkage assembly has a first end, a second end and a pivot joint therebetween. The first end of the linkage assembly is rotatably coupled to the harness and the second end of the linkage assembly is rotatably coupled to the rotor blade. A first lock assembly selectively secures the rotor blade to the grip assembly and the harness when the rotor blade is in the radially extended orientation. A second lock assembly selectively secures the rotor blade relative to the harness when the rotor blade is in the stowed orientation.

Abstract: A tiltrotor aircraft having a VTOL flight mode, a forward flight mode and a storage mode includes a fuselage having a wing rotatably mounted thereto. The wing has an orientation generally perpendicular to the fuselage, in the flight modes, and an orientation generally parallel to the fuselage, in the storage mode. First and second pylon assemblies are positioned proximate outboard ends of the wing. First and second mast assemblies are respectively rotatable relative to the first and second pylon assemblies and have generally vertical orientations, in the VTOL flight mode, and generally horizontal orientations, in the forward flight mode and the storage mode. First and second proprotor assemblies are respectively rotatable relative to the first and second mast assemblies. Each proprotor assembly includes a plurality of rotor blades and has a radially extended orientation, in the flight modes, and a stowed orientation, in the storage mode.
