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]
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.
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]
1. Preheat the oven to 300°. On a rimmed baking sheet, season the ribs with salt, pepper and garlic. Drizzle with oil and scatter the cloves over the ribs and in the pan. Pour the beer over the ribs, cover with foil and bake for 2 hours, until the meat is tender. 2. Strain the pan juices into a saucepan.
The recipe said to cook the ribs for closer to 1 1/2 hours, but I kept them in a little longer. Pascale Mondesir Garten's recipe said to cook the ribs in a 350-degree oven for 1 1/2 hours for baby ...
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.
Preheat the oven to 350°F (180°C). Combine the garlic, shallot, peanut and cilantro with the tomato sauce, soy sauce and olive oil and mix well into a marinade.
In ships, frames are ribs that are transverse bolted or welded to the keel. Frames support the hull and give the ship its shape and strength. In wooden shipbuilding, each frame is composed of several sections, so that the grain of the wood can follow the curve of the frame.
