Folding wing arrangement with axial-flux motor

An aircraft wing, comprising:

• a fixed wing;
• an outboard wing section outboard of the fixed wing;
• and
• a hinge assembly connecting the outboard wing section to the fixed wing, wherein,
• the aircraft wing is configurable between:
• (i) a flight configuration for use during flight and
• (ii) a ground configuration for use during ground-based operations, in which ground configuration the outboard wing section is rotated away from the flight configuration about a hinge axis of the hinge assembly, such that the span of the aircraft wing is reduced,
• wherein,
• the hinge assembly comprises:
• a fore set of interleaving lugs and an aft set of interleaving lugs;
• a fore hinge pin and an aft hinge pin, extending through the fore and aft sets of interleaving lugs respectively, thereby forming a hinge having a hinge axis coaxial to the longitudinal axes of the hinge pins;
• and
• a Geared Rotary Actuator (GRA) sandwiched between the fore sets of lugs and the aft sets of lugs, the GRA being configured to rotate the outboard wing section about the hinge axis to move the wing between the flight configuration and the ground configuration;
• wherein the wing further comprises:
• a locking and latching unit (LLU), positioned inboard of the GRA;
• wherein
• the LLU comprises an aft latch pin and a fore latch pin, the latch pins being moveable between retracted positions in which the latch pins are housed in the LLU, and respective extended positions in which the aft latch pin extends rearwardly, and the fore latch pin extends forwardly
• such that when the wing is in the flight configuration and the latch pins are in the extended positions, the outboard wing section is latched to the fixed wing,
• and wherein the wing further comprises:
• a power control unit comprising axial-flux motor,
• a GRA transmission for transferring rotary output of the motor to the GRA, and
• an LLU transmission for transferring rotary output of the motor to the LLU,
• wherein
• the power control unit is located inboard of the GRA and inboard of the LLU and the power control unit is configured to selectively transfer the rotary output of the axial-flux motor into the GRA or into the LLU, via the respective transmission.
