Patents were supported by Boulton & Paul Ltd in 1929.〔(1930 Canadian patent CA 304755 by Hubert Townend with drawings )〕 In the United States it was often called a "drag ring". It caused a reduction in the drag of radial engines and was widely used in high-speed designs of 1930-1935 before the long-chord NACA cowling came into general use. Examples of aeroplanes with Townend rings were the Douglas O-38, Vickers Wellesley, the Westland Wallace and the Gloster Gauntlet. Early claims portrayed it as a superior design to the NACA cowling, but later comparisons proved aircraft performance worse when using a Townend ring at airspeeds above 250 mph. 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「Townend ring」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.
