Longerons, struts and stringers in a truss type fuselage structure [2]: 3–4 In an aircraft fuselage, stringers are attached to formers (also called frames) [3] and run in the longitudinal direction of the aircraft. They are primarily responsible for transferring the aerodynamic loads acting on the skin onto the frames and formers.
Wellington Mk.X HE239 of No.428 Sqn. RCAF, illustrating the geodetic construction and the level of battle damage it could sustain and still return to base. The earliest-known use of a geodetic airframe design for any aircraft was for the pre-World War I Schütte-Lanz SL1 rigid airship's envelope structure] of 1911, with the airship capable of up to a 38.3 km/h (23.8 mph) top airspeed.
These environments include, but are not limited to: science platform aircraft and aircraft-deployable systems; space vehicles, space stations, habitats and lunar and planetary surface construction bases; and Earth-based control, experiment, launch, logistics, payload, simulation and test facilities. Earth analogs to space applications may ...
Alloy 7075-T6 (70,000-psi yield strength), an Al-Zn-Mg-Cu alloy, was introduced in 1943. Since then, most aircraft structures have been specified in alloys of this type. The first aircraft designed in 7075-T6 was the Navy’s P2V patrol bomber. A higher-strength alloy in the same series, 7178-T6 (78,000-psi yield strength), was developed in ...
An aerostructure is a component of an aircraft's airframe. This may include all or part of the fuselage, wings, or flight control surfaces.Companies that specialize in constructing these components are referred to as "aerostructures manufacturers", though many larger aerospace firms with a more diversified product portfolio also build aerostructures.
There is a long-standing convention within WikiProject:Aircraft that specifications for US, Canadian and UK aircraft (for the UK periods differ - e.g. RAF aircraft until post war used mph, FAA aircraft operated in knots) should be given as English units first, and all others as SI units first.

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.
