The Gulfstream G650 is a twin-engine business jet airplane produced by Gulfstream Aerospace.〔("Gulfstream Introduces the All-New Gulfstream G650" ). Gulfstream, March 13, 2008.〕 The model is designated ''Gulfstream GVI'' in its type certificate.〔(FAA Type Certificate No. T00015AT, Revision 4; Gulfstream GVI ) retrieved October 22, 2013〕 Gulfstream began the G650 program in 2005 and revealed it to the public in 2008. The G650 is the company's largest and fastest business jet with a top speed of Mach 0.925. The aircraft project was named the 2014 winner of the Collier Trophy, for having "strengthened business aviation through significant technological advancements in aircraft performance, cabin comfort, and safety." The G650ER is an extended-range version of the G650.〔(【引用サイトリンク】url=http://airstreamjets.com/aircraft-options/private-jets/long-range-jets/gulfstream-g650/ )〕 ==Design and development== The Gulfstream G650 was formally launched as an internal company project in May 2005, and publicly unveiled on March 13, 2008. At the public announcement occasion, company executives stated the new model would become Gulfstream's largest, fastest and most expensive business jet on entry to the market.〔New Gulfstream, Flying Magazine, Vol. 135., No. 5, May 2008, p. 52.〕 The G650 has a cruise speed of Mach 0.85 to 0.90, with maximum speed of Mach 0.925 and a range of up to . It can be equipped with a full kitchen and bar and may be equipped with a variety of entertainment features including satellite phones and wireless Internet. The jet uses two Rolls-Royce BR725 engines, each producing a maximum thrust of .〔("Rolls-Royce presents BR725 engine to power new Gulfstream G650" ), Rolls-Royce, March 13, 2008.〕 Gulfstream states that with a weight of less than , it is able to land at small airports avoiding the busy airports around the world. To provide better usage of the internal volume, Gulfstream designers rejected the usual circular fuselage cross-section in favor of an oval which uses a flatter lower portion.〔Warwick, Graham. ("Gulfstream G650 - in the cabin" ). Flightglobal.com, 13 March 2008.〕 The cabin is wide and high.〔 The fuselage is of metal construction; composite materials are used for empennage, winglets, rear pressure bulkhead, engine cowlings, cabin floor structure and many fairings. The eight oval cabin windows on each side of the fuselage are wide. Panels are bonded rather than riveted, reducing parts count compared to the G550.〔(Gulfstream Expansion Spurs Production Evolution )〕 The wing uses greater sweep (36 degrees) than previous Gulfstream aircraft (for example, the G550 wing has 27 degrees of sweep). It does not use leading-edge high-lift devices, and tracks for rear-mounted flaps are completely enclosed within the airfoil contour. The wing's leading edge is a continuously-changing curve, and the airfoil varies continuously from root to tip (the tip incorporates winglets). The aircraft controls are completely fly-by-wire, with no mechanical control between pilot and flight surfaces. The surfaces are moved by dual hydraulic systems. More airliners today are using fly-by-wire, but only one other current business jet (Dassault Falcon 7X) is so equipped. The G650 shares its yokes and column with the G550 in an effort to receive a common type rating.〔Warwick, Graham. ("Gulfstream G650 - in the cockpit" ). Flightglobal.com, March 13, 2008.〕 The wing design was completed in 2006. A total of 1,400 hours of wind tunnel testing was completed by 2008. A pressure-test fuselage was built and tested, including an ultimate-pressure test of 18.37 psi.〔Flying May 2008, p. 56.〕 The G650 taxied under its own power for the first time on September 26, 2009.〔("Photo Exclusive: The Gulfstream G650" ). ''The Enterprise Report.com'', September 27, 2009.〕 A public rollout ceremony was later held on September 29, 2009.〔Larson, George. ("Gulfstream G650 Rolls Out" ). ''Aviation Week'', September 29, 2009.〕 The G650 had its maiden flight on November 25, 2009.〔(PICTURES: G650 takes to the skies )〕 Flight testing for the maximum operating speed of Mach 0.925 was announced as completed on May 4, 2010.〔Alton K. Marsh.(Gulfstream G650 reaches near speed of sound ). AOPA Online, 4 May 2010 (accessed May 9, 2010)〕 Gulfstream reported on August 26, 2010 that the G650 hit a maximum speed of Mach 0.995 during a dive as part of its 1,800-hour flight test program.〔("Gulfstream G650 Reaches Mach 0.995" ). Gulfstream.com, August 26, 2010.〕 In April 2011, a G650 crashed during flight testing. The G650 test aircraft were grounded until May 28, 2011, when the remaining test aircraft were allowed to return to flight testing.〔("Investigators seek clues in G650 Crash" ).〕 On September 7, 2012, the G650 received its type certificate from the US Federal Aviation Administration (FAA).〔Mayle, Mary Carr. "(Gulfstream G650 gets FAA certification )" ''Savannah Morning News'', 8 September 2012. Retrieved: 8 September 2012.〕〔Brown, Sarah. "('Ultra-ultra' G650 gets type certificate )" ''Aircraft Owners and Pilots Association'', 7 September 2012. Retrieved: 8 September 2012.〕 Its first delivery was to an American customer named Preston Henn on December 27, 2012.〔(【引用サイトリンク】title=First G650 Delivered )〕 The G650 had a nominal list price of $64.5 million in 2013,〔 but there was a three-year waiting list. Some aircraft produced for delivery in 2013 sold for more than $70 million to buyers that wanted to take immediate delivery.〔Whyte, Alasdair. ("Second G650 trades" ). Corporate Jet Investor, November 22, 2013.〕 On May 18, 2014, Gulfstream announced at the annual European Business Aviation Association exhibition, that it had developed an extended range version called the ''G650ER''. The G650ER is capable of flying at Mach 0.85, due to its increase in fuel capacity. Gulfstream stated that a G650ER development aircraft had flown non-stop from Hong Kong to Teterboro, New Jersey, U.S. in March, a distance of ; it had also flown non-stop from Los Angeles to Melbourne in Australia. The extra fuel is housed in existing space inside the G650's wings and aircraft already built may be quickly upgraded to the ER version. The G650ER received its certification in October 2014 and began deliveries in late 2014 ahead of its 2015 target.〔Trautvetter, Chad. "(Globe-girdling Gulfstream G650ER Gets Its Wings )" ''AINonline'', 9 October 2014. Accessed: 19 May 2015.〕〔Garvey, William & Salerno. Jessica A. "(Gulfstream 650ER Enters Service )" ''Aviation Week'', 1 January 2015. Accessed: 19 May 2015.〕 The G650ER attempted two world records from New York to Beijing to Savannah in February 2015.〔("This Gulfstream Flew Around the World With Just One Fuel Stop" ). ''Popular Mechanics''〕 Also in May 2014, Gulfstream confirmed that the G650 would be offered to the United States Air Force for its program to replace the E-8C JSTARS air-to-ground surveillance and targeting aircraft. The still emerging requirements call for an aircraft with a 10-13 man crew and a belly-mounted radar long.〔("Gulfstream to pitch G650 for JSTARS replacement" ).
