The Airbus A330neo is a wide-body twin-engine jet airliner currently under development by Airbus to replace the Airbus A330 (now A330''ceo'' ("Current Engine Option")). There will be two variants of the A330neo, the A330-800neo and the A330-900neo.〔(【引用サイトリンク】 title=Living up to its billing: Airbus officially launches the A330neo programme )〕 The letters ''"neo"'' in the name stand for "New Engine Option". The Rolls-Royce Trent 7000 will be the only engine to power the airliner.〔 The A330neo will also feature other enhancements such as winglets (inspired by the Airbus A350), a longer wingspan (64 meters) and new engine pylons. According to Airbus, these enhancements will reduce the fuel burn per seat by 14%, with additionally lower capital cost making the A330neo the most cost-efficient medium-range wide-body aircraft in the market.〔(Leahy Sees Ten Per Month Airbus A330neo Rate ) Aviationweek〕〔(【引用サイトリンク】 title=Airbus launches the A330neo )〕〔(UPDATED ANALYSIS: Delta Order for A350; A330neo Hinged on Pricing, Availability ) Airwaysnews〕 ==Development== Airbus's management had been studying whether to equip the A330, its bestselling wide-body airliner, with newer and more efficient engines: "New Engine Option", or ''"neo"'' to maintain sales. Airbus sales chief John Leahy felt it was competitive at mid-range routes with that of the Boeing 787, even without new engines. It was also the most inexpensive widebody positioned to serve high density routes shorter than and had the potential to create a monopoly in that market segment.〔Flottau, Jens, "Defining priorities", Aviation Week and Space Technology, 14 July 2014, p. 70.〕 Moreover, customers such as AirAsia X and Delta Air Lines, were interested in a re-engined A330 and pushed Airbus to develop one.〔 However, an A330neo could have also caused problems for Airbus; being in the same twin-aisle market segment as the Airbus A350, the A330neo could have hampered its sales.〔 On 14 July 2014, Airbus announced the A330neo programme at the Farnborough Airshow.〔 The A330neo will use the Rolls-Royce Trent 7000 engine, which is an electronic controlled bleed air variant of the Trent 1000 used for the Boeing 787-10. It will have a diameter fan, with a 10:1 bypass ratio and delivering a thrust of of thrust.〔(【引用サイトリンク】 title=A330neo: Powering into the next decade )〕 The A330neo will also feature other enhancements such as winglets (inspired by the Airbus A350), a longer wingspan (by 3.7 meters) and new engine pylons. The enhancements together with seat increase will reduce the fuel burn per seat by 14% on a flight, and increase range by .〔〔 The A330neo would also have more seats than its predecessor.〔 According to Airbus, the A330neo will be the most cost efficient medium range wide body aircraft in the market.〔 The decision to offer the aircraft with only one engine option is not unique to Airbus; the Boeing 777X will come equipped exclusively with General Electric GE9X engines. Airbus has pointed out that equipping a commercial aircraft to handle more than one type of engine increases development costs, however a similar engine also made by Rolls Royce, the Trent 1000 ALPS, is expected to be an available option as early as 2020. The head of Pratt and Whitney told the ''Wall Street Journal'', "Engines are no longer commodities...the optimization of the engine and the aircraft becomes more relevant." Both GE and R-R wanted an exclusive deal on the neo, however GE dropped its bid to be the engine supplier of the neo after Boeing chose them to be the exclusive engine supplier for their upcoming Boeing 777X.〔Wall, Robert, Jon Ostrower and Rory Jones, "Aircraft makers curb engine choices", ''Wall Street Journal'', July 16, 2014, p.B3〕 On November 7, 2015, Airbus announced that the A330neo will feature a distinctive cockpit windscreen design similar to the A350. 〔(【引用サイトリンク】 title=“Shades” livery now also on new A330neo )〕 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「Airbus A330neo」の詳細全文を読む スポンサード リンク
