The Armstrong Whitworth A.W.52 was a British flying wing aircraft design of the late 1940s.

[edit] History

Armstrong Whitworth Aircraft proposed a jet-powered four-engine flying wing bomber design, utilitising a laminar flow wing, during the Second World War. The design was tested on a third-scale glider known as the A.W.52G, but the war ended and the project was dropped.

However, Armstrong Whitworth then received a contract that would allow them to produce two prototypes for evaluation, nominally for a mail carrying aircraft. The first prototype flew on 13 November 1947 powered by two Rolls Royce Nene engines. This was followed by the second prototype on 1 September 1948 with the Rolls Royce Derwent. The first prototype crashed without loss of life in May 1949, making it the first occasion of an emergency ejection by a British pilot, but the second prototype remained flying with the Royal Aircraft Establishment until 1954.

[edit] The accident

On 30 May 1949, test pilot Jo Lancaster encountered a pitch oscillation while diving at 320 mph, believed to be a result of elevon flutter. Starting at two cycles per second, it rapidly increased to incapacitating levels. With structural failure seemingly imminent, Lancaster bailed out of the aircraft using its Martin-Baker Type 1 ejection seat, becoming the first British pilot to use the apparatus in a "live" emergency.[1]
