The Gulfstream G200, formerly known as the IAI Galaxy is a twin-engine business jet. It was designed originally by Israel Aircraft Industries (IAI) and was produced for Gulfstream Aerospace from 1999 through 2011. ==Design and development== The G200 was originally named "Astra Galaxy". Israel Aircraft Industries' subsidiary Galaxy Aerospace Inc began designing the Galaxy in the late 1980s in a risk-sharing partnership with the Soviet aircraft design bureau Yakovlev OKB.〔Gunston, Bill and Yefim Gordon. ''Yakovlev Aircraft since 1924''. London, UK: Putnam Aeronautical Books, 1997. ISBN 1-55750-978-6.〕 The program officially launched in September 1993. Yakovlev handled design and manufacturing of the forward fuselage and empennage. However, the Russian company had trouble meeting agreed production schedules, and the partnership was ended in 1995.〔("Corporate Aircraft, Astra Jet" ). ''Flight International'', 12–16 June 1996.〕〔("IAI stars in Galaxy production reshuffle" ). ''Flight International'', 4 October 1995.〕 This led to another risk-sharing agreement, with EADS Sogerma manufacturing the fuselage and empennage, and IAI being responsible for final assembly and other prime contractor duties. The Galaxy was based on a new wider fuselage, attached to a strengthened Astra SPX wing with integrated winglets and modified high lift devices, powered by new 5,700 lb (25.3 kN) thrust Pratt & Whitney Canada PW306 turbofans, and with improved Pro Line 4 avionics and all-new interior. The decision to use the existing Astra SPX wing imposed a limit on maximum size, but allowed for a fuselage large enough to accommodate three-abreast seating. The main change from the Astra SPX wing was the introduction of Krueger flaps on the leading edges of the inboard section. These recovered some of the field performance lost as a result of the Galaxy's higher wing loading.〔〔Moxon, Julian, "Exploring the Galaxy; The Galaxy "Super Mid-Size". Business Jet Aims to Lower the Price of Large Cabin Comfort", Flight International, 30 September - 6 October 1998, pp. 65-69.〕〔 It used rubber de-ice boots on wing and horizontal stabilizer leading edges. The aircraft has seating configurations for 8 to 10 passengers.〔 The G200 has a forward tilting stance when on the ground. The Galaxy first flew on December 25, 1997. By December 1998 it had received certification from the US and Israeli aviation agencies. Deliveries began the following year.〔〔(G200 Overiew ). Gulfstream. Retrieved May 12, 2009.〕 The Galaxy was renamed "G200" after Gulfstream Aerospace acquired Galaxy Aerospace in June 2001.〔( Israel IAI-1126 Galaxy/Gulfstream G200 ). Airliners.net.〕 The final production G200 rolled off the production line on December 19, 2011; 250 units had been built. In 2005, Gulfstream began designing a follow-on aircraft. The new model, known as the ''G250'' was launched in 2008.〔"Gulfstream raises the bar with the G250". ''Flight International'', 7–13 October 2008, p. 27.〕〔("NBAA 2008: Gulfstream know-how buoys G250 performance claims" ). Flight International〕 It was later renamed the Gulfstream G280. 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「Gulfstream G200」の詳細全文を読む スポンサード リンク
