What is the structural design of a wing?
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. The term swept wing is normally used to mean swept back, but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing.The key geometric parameters used to describe the shape of a wing are span, semi-span, chord, and sweep angle. It is essential to learn their definitions.A wing is a type of fin that produces both lift and drag while moving through air. Wings are defined by two shape characteristics, an airfoil section and a planform.A variable-sweep wing, colloquially known as a swing wing, is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft’s shape to be changed, it is a feature of a variable-geometry aircraft.
What is wing structure analysis?
Structural analysis of the airplane wing is conducted to define the geometry of the wing spars and skin. The wing section is designed to have two spars, one at a quarter of the cord position and one at the three quarters of the cord. Spars are the principal structural members of the wing. They are placed from the fuselage to the tip of the wing taking over most of the forces. Ribs are structural crosspieces of the wing extending from the leading edge to the trailing edge of it.The main spar is the primary structural member of a wing, carrying most of the applied bending and shear loads. The skin carries most torsional loads and transfers the stresses to the wing ribs.
