✔️📘✏️Aircraft wing is a framework made chiefly of spars, ribs, and
✔️📘✏️Spars are the main members of the wing.They extend lengthwise of the wing
(crosswise of the fuselage). All the load carried by the wing is ultimately taken by the spars.
✔️📘✏️Most wing structures have two spars, the front spar and the rear spar.
✔️📘✏️The front spar is found near the leading edge while the rear spar is about two-thirds the distance to the trailing edge.Depending on the design of the flight loads, some of the all metal wings have as many as five spars.
✔️📘✏️In addition to the main spars, there is a short structural member which is called an aileron spar.
✔️📘✏️Ribs are the parts of a wing which support the covering and provide the airfoil shape.
✔️📘✏️These are also called forming ribs and their primary purpose is to provide shape.Ribs that takes flight stress, are called compression ribs.
✔️📘✏️The skin on a wing is designed to carry part of the flight and ground loads in
combination with the spars and ribs.This is known as a stressed-skin design.
✔️📘✏️In flight the loads gets transmitted through the skin to the ribs and ultimately to the spar.
