翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ground carriage ： ウィキペディア英語版 Ground carriage An aircraft ground carriage (also "ground power assisted takeoff and landing concept") is a landing gear system connected to the ground, on which aircraft can take off and land without their aircraft-installed landing gear. The technical feasibility of the ground carriage is being investigated by two research groups. In 2013, IATA included the technology into their "Technology Roadmap"; Airbus pursues the concept as part of its "Future by Airbus” strategy. == Advantages and functionality == The aircraft-installed landing gear and related structures and systems account for 6 to 15 per cent of the empty weight of an aircraft, but it is only required on the ground for takeoff and landing as well as for taxiing and parking. During cruise flight, it is carried along as unused ballast. An aircraft without landing gear could therefore require 8 to 20 per cent less fuel in flight. Furthermore, landing gears are one of the most expensive aircraft systems and complex in operation and maintenance. Finally, less noise is emitted when the drag of the undercarriage is omitted during approach and the engines are switched off while taxiing on ground. A ground carriage provides the means for an aircraft to takeoff and land without carrying an own aircraft-installed landing gear. Instead, the aircraft is equipped with much lighter interfaces, which connect to the ground carriage.〔 Every airport approached by aircraft without landing gear must operate at least one ground carriage. In addition, alternate airports must be available if an airport is closed due to bad weather or a system failure. For emergency landings outside of runways, unsuitable flooring or unpaved ground cannot absorb the high wheel loads. Therefore, the landing gear of heavy long-haul aircraft in emergency landing on unsuitable ground is often not extended, since it would otherwise sink into ground first and then bend or break off.〔 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「Ground carriage」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.
