Vickers Transonic Research Rocket was developed from the Miles M.52 a British supersonic research aircraft a project which was undertaken in top secrecy between 1942 and 1945 to a Ministry of Supply specification E.24/43. The project was cancelled because the Government of the day was persuaded that with the accumulation of data it was felt that the E.24/43 aircraft was unlikely to reach sonic speed. Wind-tunnel model tests apparently indicated serious loss of longitudinal stability at high subsonic speed as was then characteristic of existing aircraft. The decision was reached to acquire preliminary experience of flight under transonic conditions using rocket-driven pilotless scale models.The Ministry of Supply (MOS) formed the Guided Projectile Establishment under W. P. Cooke at Westcott, Buckinghamshire, and the Rocket Propulsion Group under A. D. Baxter at RAE, Farnborough. Work commenced in applying German technology, with the Halstead Experimental Centre of the MOS monitoring commercial exploitation. ==Development== A contract was placed in 1945 with Vickers Armstrong Limited for the design and construction of several test vehicles. Early in 1946 the contract for the E.24/43 was cancelled, since it was felt impossible to ensure the safe escape for the pilot in the event of an emergency ejection at high speed. The difficulties surrounding flight at sonic speeds appeared to increase with increasing knowledge. In those circumstances consideration of an improved version of the E.24/43 was discarded in favour of pilotless models which for the initial try-out were to be 3/10-scale versions of the Miles M.52 design. For drag and stressing reasons the operational altitude had to be in the stratosphere to which altitude the test vehicles would be carried by a parent aircraft, a De havilland Mosquito 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「R.A.E. – Vickers Transonic Research Rocket」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
