Chertok's elaboration of the German R-15 cruise missile design. By 1951 - 1953 the Korolev bureau had prepared an experimental design, incorporating a prototype astronavigation system. In 1953 an expert commission examined the design and felt that there were still many technical problems needing to be solved, which would be better handled by an aircraft designer rather than Korolev. Additionally, Korolev's chief priority was the development of the R-7 ICBM. In 1954 a government decree authorised the Lavochkin and Myasishchev aircraft design bureaus to proceed in parallel with full-scale development of trisonic intercontinental cruise missiles. The EKR as designed by Korolev would have been a Mach 3 ramjet, accelerated to supersonic cruise speed by an R-11 rocket booster. Smaller than the missile proposed by the Germans, it would have had a range of 730 km with a flight time of 927 seconds, a lift to drag ratio of 2.51, and a wing area of 3.31 m². ==Specifications== 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「EKR (missile)」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.
