翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Barrel roll ： ウィキペディア英語版 Barrel roll A barrel roll is an aerial maneuver in which an airplane makes a complete rotation on both its longitudinal and lateral axes, causing it to follow a helical path, approximately maintaining its original direction. It is sometimes described as a "combination of a loop and a roll."〔(【引用サイトリンク】title=Aerobatic Figures )〕 The g-force is kept positive (but not constant) on the object throughout the maneuver, commonly between 2–3 g, and no less than 0.5 g.〔(【引用サイトリンク】url=http://www.fulldeflection.com/index.php/manoeuverscatalogue/42-catalogue/48-barrel-rolls )〕 ==Etymology== The barrel roll is so named because an aircraft executing this maneuver looks as though it were flying with its wheels running around the inside wall of a cylinder, or an imaginary barrel lying on its side. A more common modern visualization is to imagine an airplane trying to fly in a horizontal corkscrew around the line of the direction of travel.〔''Advanced Control of Aircraft, Spacecraft and Rockets'' By Ashish Tewari -- John Wiley and Sons 2011 Page 193〕 Although the maneuver predates the name, the term was first used in 1917, gaining popularity during the early 1930s.〔''Merriam-Webster's Collegiate Dictionary: Eleventh Edition'' By Merriam-Webster Inc -- 2011 Page 100〕 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「Barrel roll」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.
