The internal structure of wing consists of spars, ribs, stringers, and formers. The chief structural member of wing is spar as shown in Figure 1.3. The internal structure of wing is covered by wing skin, which is also able to carry a part of wing stress. The applied load and stresses are transmitted from the wing skin to the ribs and subsequently to the spars during flight. The spars act as an important member that not only supports distributed load on the wing structure but also the concentrated weight of the fuselage and landing gear.
Design of Wind Turbines

One type of larger blade was constructed like an airplane wing with a spar, ribs, and a covering. The spar is the load-bearing element and the ribs form the airfoil shape. As noted earlier, fabrication of blades depends on design, materials, and the construction processes, all of which are related. Wind turbine blades have been made from a number of materials, for example, aluminum, fabric, or metal covers on ribs and spars (like an airplane wing). Other examples are a sail wing made of fabric attached to a leading edge spar; a laminated wood composite shell; berglass-reinforced plastics (FRPs) and carbon bers; pultruded FRPs; extruded aluminum (blades for vertical axis wind turbines); and small turbine blades made from injection molds.

Spar is one of the prime structural members in the wing structure, constructed at span-wise at perpendicular to the fuselage as shown in Figure 2. The spar carries the whole weight of the wing. Rib is another main member in the wing structure which is attached to spar. Skin is as of the minimum thickness from 0.015 to 0.025 inches for resisting the pressure applied on it while flying on the sky. The skin has the moderate hardness and strength to resist the ground damages such as stones, debris etc.
