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 "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, [2] and was typical of light aircraft built until the advent of structural skins, such as fiberglass and other composite materials. Many of today's light aircraft, and homebuilt aircraft [3] in particular, are still designed in this way.
The P.10 was not the first metal British aircraft, for the unlikely looking Seddon Mayfly holds that priority; but it never had a realistic hope of flight. [1] One lesser novelty, which was to become a standard Boulton & Paul feature was the mounting of the Lucifer on a hinge so that it could be swung sideways for servicing without ...
The British ARV Super2 light aircraft has a fuselage constructed mainly of aluminium alloy, but with some fibreglass elements. The cockpit is a stiff monocoque of "Supral" alloy, but aft of the cockpit bulkhead, the ARV is conventionally built, with frames, longerons and stressed skin forming a semi-monocoque.
A typical metal spar in a general aviation aircraft usually consists of a sheet aluminium spar web, with L- or T-shaped spar caps being welded or riveted to the top and bottom of the sheet to prevent buckling under applied loads. Larger aircraft using this method of spar construction may have the spar caps sealed to provide integral fuel tanks.
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 ] In recent years, there has been an increasing use of composite materials within the wingbox; this trend has largely been pursued to achieve lower weights over designs only using conventional materials.
Stringer (aircraft), or longeron, a strip of wood or metal to which the skin of an aircraft is fastened; Stringer (slag), an inclusion, possibly leading to a defect, in cast metal; Stringer (stairs), the structural member in a stairway that supports the treads and risers; Stringer (surfing), a thin piece of wood running from nose to tail of a ...
The tail boom uses conventional semi-monocoque construction, supported by closely spaced notched channel-section frames and continuous stringers, absent of any major longitudinal sections or longerons. The cranked section carrying the tail rotor and trim plane is more robust, strengthened by a solid-web spar, frames, and stiffeners. [7]
