Definition
The internal framework of an aircraft wing, made up of spars (the main lengthwise beams), ribs (the cross-pieces that give the wing its shape), and a covering or skin. Together these components carry the aerodynamic loads of flight and transfer them into the fuselage.
Plain English
The skeleton inside the wing — the beams, ribs, and skin that give the wing its shape and let it carry the weight of the aircraft in flight.
Context Anchor
Seen in discussions of pressure distribution, lift, and how the forces on the wing are carried by the airplane.
Derivation
Structure comes from a Latin word meaning “to build” or “to arrange.” That fits the aviation use: wing structure is not just the wing’s outside shape, but the built arrangement of parts that supports the wing.
Why Pilots Care
A wing that cannot handle pressure loads will deform or fail, directly affecting flight safety and aircraft integrity.
Intuition Check
Do not read “wing structure” as only the visible outside of the wing. Here it means the supporting built assembly of the wing, including the parts that carry loads inside it.
Example Sentence 1
During preflight, the pilot inspected the wing structure for any signs of skin wrinkling, loose rivets, or damage near the spar.
Example Sentence 2
Uneven pressure distribution places higher stress on certain parts of the wing structure during turns.
