摘要

In Keith Hayward's January Last Word under the paragraph 'Supersonic at last', he states: "The year (1948) also saw the termination of the Miles M52 Programme, a sorry and half-hearted attempt to take the UK into the era of supersonics, which the Americans had already pioneered." In fact the Miles M52 was abandoned abruptly in February 1946 when the Director General of Scientific Research at the Ministry of Aircraft Production, Sir Ben Lockspeiser, informed FG Miles that the programme to build a British supersonic aeroplane had been terminated and all work on it must cease immediately. This decision, and the haste in which not only the jigs and tools were broken up but the Ministry of Supply ordered to hand all technical data and wind tunnel results to the US, remains controversial to this day. Much work had been conducted at the Royal Aircraft Establishment, on the aerodynamic shape of the M52 straight, thin, wings, and significantly the all-moving tail. Furtherrnengine development work included a modified W2/700 jet engine with an augmented fan and afterburners, which were tested, the prototype unit being on display at the FAST Museum. While the bypass engine would have been what is now regarded as a turbofan, the addition of reheat would have boosted top speed to a supersonic level. There was much argument within the RAE and Government circles regarding the importance of swept wings to obtain a Mach 1 + performance, and glide tests of such an RAE design in 1947 were halted after the test aircraft was destroyed. However, a rocket-powered large scale model of the M52 shape, dropped from a Mosquito nearly two years after the project cancellation, as a part of Operation Neptune (drop-testing various powered models) did reach Mach 1.38 in level flight, validating the practicality of the M52 design to go supersonic. The rocket-powered Bell X-1 took the title on 14 October 1947. Keith was quite right to say we never did catch up but this was as a direct result of a succession of muddled official policies rather than the ability of the then highly innovative aircraft industry and the outstanding capabilities vested in the Government's own research establishments, which had absorbed much additional German scientific talent post-1945.
