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 ...
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.
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.

In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in tension.
[note 1] In a flying boat hull or floatplane float, the longitudinal line of sharp change in cross-section where the bottom plane meets the sidewall is an example of a chine. On some supersonic aircraft a chine extends sideways for some distance, with a very sharp edge blending in with the main wing leading edge root.
Aircraft utilizing three or more spars are considered multi-spar aircraft. Using multiple spars allows for an equivalent overall strength of wing, but with multiple, smaller, spars, which in turn allow for a thinner wing or tail structure (at a cost of increased complexity and difficulty of packaging additional equipment such as fuel tanks ...
The Cessna 172 Skyhawk is the most produced aircraft in history.. An aircraft (pl.: aircraft) is a vehicle that is able to fly by gaining support from the air.It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, [1] or, in a few cases, direct downward thrust from its engines.
