The Gulfstream G500 and G600 (GVII) are twin-engine business jets designed and manufactured by Gulfstream Aerospace. The G500 will replace the G450, flying nearly 30 knots (56 km/h) faster and 18% farther with the same fuel burn. The larger G600 will succeed the G550.
Both aircraft were unveiled by Gulfstream Aerospace on October 14, 2014, with the G500 taxiing under its own power. It first flew on May 18, 2015. It is planned to be certified in 2017. It should be delivered from late 2017.
Both models have a four circular arcs cross-section fuselage, similar to the Gulfstream G650, with a 7 in (18 cm) reduction in width and height. Similar in dimension to the Dassault Falcon, the G500/600 have 2 in (5.1 cm) more headroom, 7 in (18 cm) more cabin width and 8 in (20 cm) more floor width than Gulfstream's G450 and G550. The fuselage has an external height of 8 ft 4 in (2.54 m), and width of 8 ft 5 in (2.57 m). The production G500 will have 14 windows, two more than the prototype models.
The wing is a supercritical design with a 0.87 to 0.88 drag divergence Mach number depending upon lift coefficient. It is based on the G650's wing design with the same 36° sweep. The G600's wingspan will be 8 ft (2.4 m) wider than the G500, allowing for 10,000 lb (4,500 kg) of additional fuel. Both models have a new tail design based on the aerodynamic shape and systems of the G650's tail.
The airframe is primarily composed of high-strength aluminum alloys with limited use of steel and titanium alloys. The horizontal stabilizer, fairings, main landing gear doors, rudder and elevators, radome, rear pressure bulkhead and winglets are composite materials. The semi-monocoque fuselage structure is made of stressed skin, frame and longeron.
The G500/G600 will be powered by the Pratt & Whitney Canada PW800 which was originally conceived for the Cessna Citation Columbus program. The PW800 is based on the Pratt & Whitney Geared Turbofan core without the gear reduction. The departure from Rolls-Royce Aero Engines is a first for Gulfstream.
Electric and hydraulic systems are from the G650, as the digital air data computers, secondary power distribution with electronics, cabin acoustical treatment, primary avionics, satcom, improved cabin management system and digital fly-by-wire system. The oxygen, cabin pressurization, landing gear control, aircraft health and trend monitoring systems are adapted from the G650. The auxiliary power unit is a Honeywell HTG400G.
It is equipped with BAE Systems active sidesticks, appearing to be mechanically linked by being electrically back-driven, the first civil aircraft to be so. The Honeywell Symmetry Flight Deck features four portrait main displays, three touchscreens on the overhead panel instead of stand-alone switches ; there is four touchscreens in the glareshield and left and right touch standby displays at each seat. The enhanced flight vision system is displayed through 42×30° field-of-view head-up display, along a complete avionics suite.
