Introducing the G650Gulfstream’s new flagship
Unveiled at lastand shown in model form on Mar 13the G650 is the most technologically advanced product yet to emerge from Savannah. Gulfstream’s risk-sharing partners on the G650 include Goodrich, Honeywell, Meggitt, Rolls-Royce, Spirit and Stork Fokker.
Gulfstream announced its latest productthe G650on Mar 13 before several thousand company workers, guests and officials, headed by General Dynamics Chairman & CEO Nick Chabraja, Gulfstream Aerospace President Joe Lombardo and Senior VP Programs, Engineering & Test Pres Henne.
The biggest, fastest, longest-range business jet yet to come out of Savannah, the G650 is a clean-sheet design developed over the past 3 years and filling a market gap between the G550 and the airliner-derived Airbus A319CJ and Boeing BBJ.
Powered by 2 new fuel-efficient Rolls-Royce BR725 turbofans, each producing 16,100 lb max takeoff thrust, Gulfstream’s new flagship will fly more than 7000 nm at Mach 0.85 (compared with the G550’s 6000 nm) and 5000 nm at Mach 0.90. MTOW is approximately 100,000 lb. Max operating speed is Mach 0.925, which will make the G650 the fastest civil aircraft on the market.
A newly designed fuselage cross section gives the G650 cabin 14 inches more width and 3 inches more height than the G550. The cabin has 30% more floor area and will seat 1118 passengers in any of 12 optional “select” floorplans. Cabin altitude will be 4850 ft at FL 510lowest in its classand the G650’s 8 windows per side will be 16% larger than current Gulfstream windows, making them the largest of any business jet.
Gulfstream designers began with the G650’s cabina generously lit space with 30% more floor area than the G550 and optional floorplans for seating up to 18 passengers.
Gulfstream is aiming to create efficiencies at all stages of the G650’s life. The company conceived and built the newly completed 308,000 sq ft G650 manufacturing facility at SAV (Savannah GA) to allow implementation of lean manufacturing techniques. Gulfstream engineers used CATIA V5, ENOVIA 3D and CFD extensively in designing and optimizing the G650, achieving significant improvements in aerodynamics and efficiency over the G550. Time between major inspections is projected at 600 hours.
Its construction makes more use of composites than previous Gulfstream aircraft, notably in the wing/body fairing (by Nordam), radome (Saint-Gobain), wing fixed trailing edges, winglets and engine cowlings (Spirit) and empennage components (Stork Fokker). The fuselage uses bonded skin panels, machined frames and precision assembly. Gulfstream says its aim is a 50% reduction both in part numbers and part counts.
The wing is larger (and 8% more efficient) than the G550 wing, with a 33° sweep and continuously variable airfoil. It retains a fixed leading edge. Overall wingspan is 99 ft 7 in.
Avionics suite will be Gulfstream’s PlaneView II flightdeck, based on the Honeywell Primus Epic. SV-PFD, EVS II and Rockwell Collins HGS6000 HUD will be standard. Thales will develop the G650’s 3-axis FBW flight control computer system.
Gulfstream is working toward first flight in the 2nd half of 2009 and says 5 aircraft will take part in the flight test program. FAA and EASA certification are expected in 2011, with entry into service in the 1st half of 2012.
As a new design, the G650 will have a separate type certificate, but the goal is to have a common pilot type rating with the G550 (with minor differences training). Gulfstream predicts that this will make the G650 attractive to customers planning a diversified fleet as well as to fleet buyers. That said, there is no program in place for G550 customers to migrate to the G650.
Flyaway price for a G650 will be $58.5 million (in 2012 dollars), rising to $59.5 million in 2013. Gulfstream elected to have no actual launch customer, but Lombardo says the company will start taking orders in mid-April. Phil Rose
