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.
Interior of a Boeing/Stearman PT-17 showing small channel section stringers. In engineering, a longeron or stringer is a load-bearing component of a framework. The term is commonly used in connection with aircraft fuselages and automobile chassis. Longerons are used in conjunction with stringers to form structural frameworks. [1]
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]
The spar carries flight loads and the weight of the wings while on the ground. Other structural and forming members such as ribs may be attached to the spar or spars, with stressed skin construction also sharing the loads where it is used. There may be more than one spar in a wing or none at all.
But by 2006, Burbank's had closed all but its original location in suburban Sharonville, Ohio. Montgomery Inn began to sell its barbecue sauce in bottles in 1990, and the ribs themselves soon after. Both are regularly available at supermarkets within a 300-mile radius of Cincinnati, and elsewhere via mail order since 1994.
A static test of the C-17 wing in October 1992 resulted in its failure at 128% of design limit load, below the 150% requirement. Both wings buckled rear to the front and failures occurred in stringers, spars, and ribs. [17] Some $100 million was spent to redesign the wing structure; the wing failed at 145% during a second test in September 1993 ...
