Metal fatigue and aircraft design flaw 6 Structural failure of the right horizontal stabiliser due to metal fatigue and aircraft design flaw 1978-06-26 Helikopter Service Flight 165: North Sea, Norway Sikorsky S-61: Fatigue 18 Rotor blade loosened after fatigue to the knuckle joint: crashed into the sea [10] 1979-05-25 American Airlines Flight 191
A blended wing body (BWB), also known as blended body, hybrid wing body (HWB) or a lifting aerofoil fuselage, [1] is a fixed-wing aircraft having no clear dividing line between the wings and the main body of the craft. [2] The aircraft has distinct wing and body structures, which are smoothly blended together with no clear dividing line. [3]
Flying wing" aircraft, such as the Northrop YB-49 Flying Wing and the Northrop B-2 Spirit bomber have no separate fuselage; instead what would be the fuselage is a thickened portion of the wing structure. Conversely, there have been a small number of aircraft designs which have no separate wing, but use the fuselage to generate lift.
Widespread fatigue caused the in-flight failure of the fuselage on Aloha Airlines Flight 243. Widespread fatigue damage (WFD) in a structure is characterised by the simultaneous presence of fatigue cracks at multiple points that are of sufficient size and density that while individually they may be acceptable, link-up of the cracks could suddenly occur and the structure could fail.

Two points on a fuselage at waterline 100/fuselage station 93 and waterline 101/fuselage station 276. Lofting coordinates are used for aircraft body measurements. The system derives from the one that was used in the shipbuilding lofting process, with longitudinal axis labeled as "stations" (usually fuselage stations, frame stations, FS), transverse axis as "buttocks lines" (or butt lines, BL ...
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.
The concept of the flying wing was born on 16 February 1876 when French engineers Alphonse Pénaud and Paul Gauchot filed a patent for an aero-plane or flying aircraft [5] powered by two propellers and with all the characteristics of a flying wing as we know it today. [6] Tailless aircraft have been experimented with since the earliest attempts ...
The vertical stabilizer of the Airbus A310-300, first flown in 1985, was the first carbon-fiber primary structure used in a commercial aircraft; composites are increasingly used since in Airbus airliners: the horizontal stabilizer of the A320 in 1987 and A330/A340 in 1994, and the center wing-box and aft fuselage of the A380 in 2005.
