Gulfstream G650

https://en.wikipedia.org/wiki/Gulfstream_G650

The Gulfstream G650 is a twin-engine business jet airplane produced by
Gulfstream Aerospace. The model is designated Gulfstream GVI in its type
certificate, and may be configured to carry from 11 to 18 passengers. 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. The 300th was delivered in April 2018, just
over five years since introduction in December 2012.

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 7,500 nautical miles (13,900 km;
8,600 mi) at Mach 0.85, due to its 4,000 pounds (1,814 kg) 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
7,494 nautical miles (13,879 km; 8,624 mi); 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. The G650ER attempted two world
records from New York to Beijing to Savannah in February 2015.

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 3.9–6 m (13–20 ft)
long.

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. The cabin is 8 feet 6 inches (2.59 m) wide and 6 feet 5
inches (1.96 m) high, allowing the craft to be configured to carry between 11
and 18 passengers. 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 elliptical cabin windows, eight on each
side of the fuselage, are 28 inches (71 cm) wide. Panels are bonded rather than
riveted, reducing parts count compared to the G550.

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, which 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. The G650 shares its yokes and column with the G550 in an effort to
receive a common type rating. While most newer airliners now employ fly-by-wire
technology, the G650 was only the second fly-by-wire business jet, after the
Dassault Falcon 7X and before the Embraer Legacy 500.
