What does a wing spar look like?
Spars are the principal structural members of the wing. They correspond to the longerons of the fuselage. They run parallel to the lateral axis of the aircraft, from the fuselage toward the tip of the wing, and are usually attached to the fuselage by wing fittings, plain beams, or a truss. The fundamental load bearing members in the wing are known as spars. aircraft wing spar made with aluminum and composites is used for simulation and analysis.
