Gulfstream III
The Gulfstream III, a business jet produced by Gulfstream Aerospace, is an improved development of the Grumman Gulfstream II. The U.S. military uses versions of the Gulfstream III as the C-20A/B/C/D/E aircraft, though later C-20 F/G/H/J are Gulfstream IV. Design and development The Gulfstream III was built at Savannah, Georgia, in the United States and was designed as an improved variant of the Grumman Gulfstream II. Design studies were performed by Grumman Aerospace Corporation in collaboration with Gulfstream American Corporation. Design of the Gulfstream III started with an effort to synthesize a completely new wing employing NASA supercritical airfoil sections and winglets. Optimization studies considering weight, drag, fuel volume, cost, and performance indicated that a substantial portion of the new wing benefit could be secured with modifications to the existing wing. As a result, the new wing concept was canceled and work began on design modifications that would retai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman Gulfstream II
The Gulfstream II (G-II) is an American twin engine business jet designed and first built by Grumman, then Grumman American and finally Gulfstream American. It was succeeded by the Gulfstream III. The first Gulfstream II flew on October 2, 1966.Taylor, John W.R., ''Jane's All the World's Aircraft 1984–85'', Jane's Publishing Company, 1984. Design The Gulfstream II is a twin-jet swept wing corporate transport powered by two Rolls-Royce Spey turbofan engines and designed to provide high speed and long range capability without sacrificing the airport performance, reliability, and other operational advantages of its predecessor, the turboprop Grumman Gulfstream I, Gulfstream I. Preliminary design of the wing was influenced by both cruise and low speed considerations. The aft-mounted engine location was selected after extensive analysis and design iterations considering aerodynamic, structural, and ground clearance requirements.

Business Jet
A business jet, private jet, or bizjet is a jet aircraft designed for transporting small groups of people, typically business executives and high-ranking coworker, associates. Business jets are generally designed for faster air travel and more personal comfort than commercial aircraft, and may be adapted for other roles, such as casualty evacuation or express package delivery, parcel deliveries, and some are used by public bodies, government officials, very important person, VIPs, or even the military. History Early developments The first small, jet-powered civilian aircraft was the Morane-Saulnier MS.760 Paris, developed privately in the early 1950s from the Morane-Saulnier MS.755 Fleuret, MS.755 Fleuret two-seat jet trainer. First flown in 1954, the MS.760 Paris differs from subsequent business jets in having only four seats arranged in two rows without a center aisle, similar to a light aircraft, under a large sliding canopy (aircraft), canopy similar to that of a fighter ...
