History The Gulfstream IV (or G-IV or GIV) and derivatives are a famous family of twinjet aircraft Produced 1985–2018
The Gulfstream IV (or G-IV or GIV) and derivatives are a famous family of twinjet aircraft, mainly for private or business use. They were designed and built by Gulfstream Aerospace, a General Dynamics company based in Savannah, Georgia, United States, from 1985 until 2018. Aircraft power is provided by two Rolls-Royce RB.183 Tay turbofans.
Upon delivery of the last G450, over 900 GIV/GIV-SP/G450 units had been produced. The last of the G450’s was delivered on 19 January 2018 after 365 deliveries over 12 years, ending a 30-year production run, to be replaced by the G500.
In 2001, Gulfstream began work on an improved version of the GIV-SP, originally designated GIV-X. It was later renamed G450. The G450 is lengthened 1 ft (0.305 m) over the G400 and shares the forward fuselage and larger cockpit of the G550. Following its first flight on 30 April 2003, production of the G450 began in October 2004, replacing the G400. The G450 has better performance and comes with the PlaneView cockpit with four 14-inch (355 mm) liquid crystal displays and a Head up display (HUD). The shorter range G350 version of the G450 was developed and received certification in 2004.
By 2018, 1990 to 1992 GIVs were for sale at $1.6-4.4 million, 1992 to 1999 GIVSPs were listed for $1.25-5.2 million, 15-year-old G300s and G400s were available for $4.5-7 million and 2006 to 2016 G450s at $9.95-23.75 million
Variants
Design
G450 updated flight deck Compared to the Gulfstream III, a decision to redesign the wing structure for weight reduction presented an opportunity for an aerodynamic redesign of the wing to reduce cruise drag and increase range. Wing contour modifications had to be restricted to the forward 65% of wing chord so that no redesign of the control surfaces would be necessary. Modification of the inboard wing would have entailed a redesign of the fuselage floor structure, consequently this region of the wing was not modified. Outboard wing modifications were aimed at reducing the peak subcritical pressure coefficient and moving it aft in an effort to reduce shock strength and increase shock sweep
