The Armstrong Whitworth A.W.52 was an early flying wing aircraft designed and produced by British aircraft manufacturer Armstrong Whitworth Aircraft.. The A.W.52 emerged from wartime research into the laminar flow airfoil, which indicated that, in combination with the flying wing configuration, such an aircraft could be dramatically more efficient than traditional designs.
The non-planar wing tip is often swept back like a raked wingtip and may also be combined with a winglet. A winglet is also a special case of a non-planar wingtip. [citation needed] Aircraft designers employed mostly planar wing designs with simple dihedral after World War II, prior to the introduction of winglets.

As a possible replacement for the pre-war Vickers Wellington medium bomber, Vickers had proposed a series of designs. The first, to meet the same specification as the Bristol Buckingham and Air Ministry Specification B.11/41, was for a high speed twin-engined medium bomber, with remote controlled turrets in engine nacelles and guns in the nose.

The company was founded by William Armstrong in 1847, becoming Armstrong Mitchell and then Armstrong Whitworth through mergers. In 1927, it merged with Vickers Limited to form Vickers-Armstrongs , with its automobile and aircraft interests purchased by J D Siddeley .
Annular box wing: A type of box wing whose vertical fins curve continuously, blending smoothly into the wing tips. An early example was the Blériot III , which featured two annular wings in tandem. Annular (cylindrical) : the wing is shaped like a cylinder.
To compensate, the mid-set wings were set at a high angle of incidence (8.5°) to confer good take-off and landing performance. [4] Flaps were included late in the design stage, but the wing incidence remained unaltered; as a result, the Whitley flew with a pronounced nose-down attitude when at cruising speed, resulting in considerable drag.
