翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Multirotor ： ウィキペディア英語版 Multirotor A multirotor〔Early in helicopter development,"multi-rotor" was used to refer to helicopters with two rotor assemblies〕 or multicopter is a rotorcraft with more than two rotors. An advantage of multirotor aircraft is the simpler rotor mechanics required for flight control. Unlike single- and double-rotor helicopters which use complex variable pitch rotors whose pitch varies as the blade rotates for flight stability and control, multirotors often use fixed-pitch blades; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque produced by each. Due to their ease of both construction and control, multirotor aircraft are frequently used in model and radio control aircraft projects〔(【引用サイトリンク】title=Multicopter Table )〕〔(【引用サイトリンク】title=FrontPage - UAVP-NG - The Open Source Next Generation Multicopter )〕〔(【引用サイトリンク】title=FrontPage - UAVP-NG - The Open Source Next Generation Multicopter )〕〔(【引用サイトリンク】title=DIY Drones )〕〔(OpenPilot ) Open source UAV autopilot for multirotors〕 in which the names tricopter, quadcopter, hexacopter and octocopter are frequently used to refer to 3-, 4-, 6- and 8-rotor helicopters, respectively.〔(【引用サイトリンク】title=How to Pick The Best Multirotor Frame )〕 == Examples == * Cierva Air Horse - a British three-rotor "heavy lift" helicopter first flying in 1948. Three rotors were used to give a large lift without compromising rotor strength.〔''Flight'' 14 April 1949 p427〕 * e-volo - a German prototype electric multicopter with 16 rotors, the first electric multicopter in the world to achieve manned flight. The large number of low-cost motors make it economical, quiet and provide redundancy with ability to maintain control with up to four failed motors. 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「Multirotor」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.
