Gulfstream G450 Long-Range Business Jet, USAGulfstream Aerospace, based in Savannah, Georgia, first displayed the long-range, large-cabin G450 business jet in October 2003, but the G450 development programme began in 2001 while the development of the G550 business jet was underway. "The G450 set a new city-pair speed record from Chicago to London in seven hours and fifteen minutes."
The first flight took place in April 2003. FAA type certification was awarded in August 2004 and in November 2004 the European Aviation Safety Agency validated the FAA certification. In January 2006, the G450 received certification from the civil aviation authority of the Commonwealth of Independent States. As of September 2007, 68 G450 aircraft were in service. RECORD-BREAKING FLIGHTS The G450 aircraft entered service in May 2005. In the week after entering service the aircraft established a new intercontinental city-pair speed record with a flight of 3,550nm from Chicago to London in seven hours and fifteen minutes at an average speed of Mach 0.85. In November 2005 the G450 set another new city-pair speed record, flying 3,290nm from Washington DC, to Luton, England, in six hours and twelve minutes, at an average speed of Mach 0.85. PERFORMANCE The aircraft can carry up to 19 passengers. Carrying eight passengers, the aircraft has a range of 8,055km - equivalent to non-stop from Madrid to Caracas or Dallas to Paris, even on a hot day. The aircraft can cruise at an altitude up to 13,715m (45,000ft), which is well above commercial airline traffic, and at speeds up to Mach 0.88 (935km/h). It can climb to 41,000ft in 23 minutes. The aircraft has a maximum take-off weight of 33,520kg and landing weight of 29,935kg. The take-off and landing field lengths are 1,660m and 970m respectively. The G350, G450, G500 and G550 business jets share the same pilot rating and many of the aircraft systems are also shared. DESIGNThe aircraft has a rear engine, T-tail configuration with low mounted wings. The airframe is of light alloy construction with advanced carbon composite ailerons, spoilers, rudders and elevator. "The Gulfstream G450 business jet can cruise at an altitude up to 13,715m and at speeds up to Mach 0.88."
The G450 aircraft design includes the proven wing, winglet and tail unit design of the G400 aircraft, a stretched fuselage 0.30m longer than the G400 and the flight deck and nose section of the G550. The aircraft design is a derivative of the GIV and GIV-SP but shares many similarities with the ultra long range G550, for example both aircraft have the PlaneView cockpit with four large flight displays and the Honeywell Primus Epic avionics and Visual Guidance System (VGS). Both G450 and G550 have the Gulfstream Enhanced Visual Guidance System (EVS). FLIGHT DECKThe PlaneView cockpit has four large liquid crystal flight displays, a Gulfstream Enhanced Vision System (EVS) with a Honeywell HUD 2020 head up display and a cursor control device. The EVS, developed by Gulfstream and Kollsman, is the first vision system of its type to be certified by the Federal Aviation Administration. The vision system gives the pilot a heightened level of situational awareness and allows greater safety. The aircraft is fitted with a Honeywell Primus Epic avionics suite. The avionics systems are installed forward of the cabin door. CABINThe cabin can seat up to 19 passengers. It can be customised to the operator’s requirements, for example with showers, an aft stateroom, galleys with countertop cooking, exercise bicycles rated to handle 2G bank angles, surround sound entertainment systems, multiple flat panel monitors, satellite telephone and DIRECTV, Broad Band MultiLink internet access (BBML), Brazilian mahogany and birds-eye maple wood cabinetry, and a choice of club seats and settees, etc. "The G450 is powered by two Rolls Royce Tay Mark 611-8C turbofan engines each developing 61.6kN."
The cabin has three separately controlled temperature zones with 100% fresh air air-conditioning and 12 heated oval widows. ENGINESThe aircraft is powered by two Rolls Royce Tay Mark 611-8C turbofan engines each developing 61.6kN. The engines are housed in nacelles of the same design as the G550. The engines are equipped with full authority digital engine control and thrust reversers. The aircraft has a Honeywell auxiliary power unit model 36-150GIV providing engine air start and run to altitudes up to 11,280m (37,000ft).
