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 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.
The front fuselage was built on four tubular longerons, but from leading edge rearwards it consisted of a set of oval formers with stringers. [1] The greatest novelty of the P.10 was that this part of the fuselage was not only a monocoque structure (still fairly unusual at the time), but a monocoque of steel with a load-bearing plastic skin ...
The company was formed in 2006, but its history can be traced back to Reuben Fleet, who commenced manufacturing operations of Fleet Aircraft on March 23, 1930. A state-of-the-art facility for the day, the plant promptly began turning out complete aircraft for military and civilian training.
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]
