Abstract: A wing assembly for an aircraft includes a torque box sleeve having an open end and a plurality of integral sides including leading, aft, top and bottom sides that jointlessly form a continuous surface having a generally airfoil shape. The wing assembly includes an internal support subassembly having a plurality of ribs coupled to a central spar. The internal support subassembly is formed into a single component outside the torque box sleeve and inserted into the open end of the torque box sleeve as the single component. The internal support subassembly is coupled to an interior of the torque box sleeve.

Abstract: A wing airframe for a wing of a tiltrotor aircraft includes a wing airframe core assembly and a wing skin assembly disposed on the wing airframe core assembly. The wing skin assembly includes a lower wing skin assembly disposed on the bottom side of the wing airframe core assembly. The tiltrotor aircraft includes a fuselage underneath the wing. The lower wing skin assembly has one or more buckle zones outboard of the fuselage. The buckle zones are locally susceptible to buckling in response to an impact of the tiltrotor aircraft, thereby protecting the fuselage from being crushed by the wing.
