In a fixed-wing aircraft, the spar is often the main structural member of the wing, running spanwise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of the wings while on the ground.
A spar is a pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include yards, booms, and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole.
One spar is usually located near the front of the wing, and the other about two-thirds of the distance toward the wing’s trailing edge. Regardless of type, the spar is the most important part of the wing.
10 sty 2022 · The wing spar is crucial to the structural integrity of the wing. You normally won’t see the spar, as it forms the internal ‘backbone’ of an airplane wing. They are usually extremely strong, and in some cases, are designed to flex to allow for a smoother ride in turbulence.
28 wrz 2022 · The spar caps are designed to the carry axial loads (tension and compression) that arise from the bending moment produced by the wing under load. In a positive g manoeuvre, the spar caps on the upper surface of the wing are in compression and the lower spar caps surface in tension.
26 cze 2024 · A wing consists of two essential parts. The internal wing structure, consisting of spars, ribs, and stringers, and the external wing, which is the skin. Ribs give the shape to the wing section, support the skin (prevent buckling), and act to prevent the fuel flowing around as the aircraft maneuvers.
A spar is a long, cylindrical, or tapering pole made of wood or metal. It is an integral part of a ship’s rigging system and plays a vital role in supporting the sails and distributing the weight and forces exerted on the vessel.
