The wing spar provides the majority of the weight support and dynamic load integrity of cantilever monoplanes, often coupled with the strength of the wing 'D' box itself. . Together, these two structural components collectively provide the wing rigidity needed to enable the aircraft to fly saf
The primary function here also is to transfer the bending loads acting on the wings onto the ribs and spar. Sometimes the terms "longeron" and "stringer" are used interchangeably. Historically, though, there is a subtle difference between the two terms.
Cantilever wings require much stronger and heavier spars than would otherwise be needed in a wire-braced design. However, as the speed of the aircraft increases, the drag of the bracing increases sharply, while the wing structure must be strengthened, typically by increasing the strength of the spars and the thickness of the skinning.
While internal wing structure commonly provides much of the strength via a combination of spars, ribs and stringers, the external skin typically carries a proportion of the loads too. On many aircraft, the inner volume of the wingbox has also been used to store fuel, which is commonly referred to as being a wet wing design. [1]
This increases the effective depth of the wing root to the height of the fuselage, making it much stiffer for little increase in weight. Typically, the ends of bracing struts are joined to the main internal structural components such as a wing spar or a fuselage bulkhead, and bracing wires are attached close by.
Instead, the false spar that carrying the aileron was used to brace the outer-most wing elements, such as the wing tips. This false spar was at a pronounced angle to that of the main spar, thus triangulating the structure; the former ran inwards from the wing tips, where they are attached to the main spars, to the final compression members of ...
Wing ribs of a de Havilland DH.60 Moth. In an aircraft, ribs are forming elements of the airframe structure of a wing, especially in traditional construction.. By analogy with the anatomical definition of "rib", the ribs attach to the main spar, and by being repeated at frequent intervals, form a skeletal shape for the wing.
The strut-braced wings of the Citabria are, like the fuselage and tail surfaces, fabric covered, utilizing aluminum ribs. Most Citabrias were built with wooden spars. American Champion has been using aluminum spars in the aircraft it has produced and has, as well, made the aluminum-spar wings available for retrofit installation on older aircraft.
