What are the main structural members of the wing in an aircraft?

The main structural members of the wing in an aircraft are the spars. Spars are the primary load-bearing components that run longitudinally along the wing, providing strength and rigidity. They are designed to withstand bending and torsional forces during flight, as the wings experience significant aerodynamic loads.

In addition to spars, other wing components such as ribs and stringers play important roles, but they function in support of or in conjunction with the spars. Ribs help maintain the wing's profile and distribute loads, while stringers help add additional structural support and shape. However, when considering the main structural members that contribute to the wing's structural integrity and strength, spars are the most critical components.
