翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Reactionless drive ： ウィキペディア英語版 Reactionless drive A reactionless drive (also known by many other names, including as an ''inertial propulsion engine,'' a ''reactionless thruster,'' a ''reactionless engine,'' a ''bootstrap drive'' or an ''inertia drive'') is a device to generate motion without a propellant, presumably in contradiction to the law of conservation of momentum. The name comes from Newton's third law, which is usually expressed as, "for every action, there is an equal and opposite reaction." A large number of infeasible devices, such as the "Dean drive", are a staple of science fiction, particularly for space propulsion. To date, no reactionless drive has ever been validated under properly controlled conditions. == Historical attempts == Through the years there have been numerous claims for functional reactionless drive designs using ordinary mechanics (i.e. devices not said to be based on quantum mechanics, relativity or atomic forces or effects). Two of these represent their general classes: The "Dean drive" is perhaps the best known example of a "linear oscillating mechanism" reactionless drive; The "GIT" is perhaps the best known example of a "rotating mechanism" reactionless drive. These two also stand out as they both received much publicity from their promoters and the popular press in their day and both were eventually rejected when proven to not produce any reactionless drive forces. The rise and fall of these devices now serves as cautionary tale for those making and reviewing similar claims.〔 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「Reactionless drive」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.
