of all Gulfstream 3 models were built, replacing the Gulfstream 2 on
the
production line. Winglets were standard on this model. The
easiest
way to differentiate between the Gulfstream 3 and the 2B is by
the
three re-shaped cockpit windows, as opposed to the four squarer ones on
the Gulf 2. Construction numbers ranged from 300 - 498, plus
unique
number 875. Two aircraft built for the Indian Air Force have
cargo
doors and only three windows each side. The Gulfstream 3 is
powered
by Rolls Royce Spey mk 511-8 turbofans and can carry up to nineteen
passengers.
It first flew on 2nd December 1979 and is 24 inches longer than the G2.
Range is around 5,129 miles, depending on the number of passengers. |

 Quiet
Technology Aerospace received certification in early
2003 for their Stage 3 hush kit for Gulfstream 2 and 3 retrofit.
It includes a 12 lobe exhaust mixer, acoustically treated carbon fibre
composite bullets in the inlet and exhaust and a translating ejector nozzle
designed to allow retention of the original Gulfstream target type thrust
reverser. Installing the hush kit does not require any change to
the engine pylon and can be installed in around ten days at a cost of 1.65
million dollars, with a weight addition of 450lb per side. Take off
and climb performance is unaffected, but a cruise penalty of five per cent
is quoted.
External differences include a lengthening of the engine pod by almost a quarterd nose of the Gulfstream 3 to the Gulfstream 2 frame. This version first flew on 17th March 1981 and can be differentiated from the Gulfstream 3 by the two squarer side cockpit windows./ |
 Really
Quiet LLC of Mojave received their certification in early
2002. This system consists of a translating ejector which is in the
aft position during take off and landing which forces gas through nozzles
into an ejector shroud that reduces velocity and noise. Once out
of this configuration the kit slides forward to become part of the main
pod. Additional weight is about 300lb and a maximum of 4 percent
performance penalty is quoted. Cost is 1.95 million and installation
requires four to six weeks.
. Once again, the visual length of the pod is increased. |
