  General Electric J79 - Encyclopedia, History, Geography and Biography
The General Electric J79 is an axial-flow turbojet engine built for use in a variety of fighter aircraft and bomber aircraft.
J79 was a single-shaft turbojet with a 17-stage compressor with a novel arrangement of variable stator blades which allow the engine to develop pressure similar to a two-stage engine at a much lower weight.
The J79 was used on the F-104 Starfighter, B-58 Hustler, F-4 Phantom II, A-5 Vigilante, IAI Kfir.

 General Electric J79 Turbojet   (Site not responding. Last check: 2007-11-03)
The General Electric J79 engine was a high-performance single-shaft turbojet that featured variable-incidence stator blades in the later high-pressure stages of its seventeen-stage compressor.
The J79 was developed as an outgrowth of the General Electric J73 engine program and was known at first as the J73-GE-X24A.
This example of the J79 is the YJ79-GE-3, the prototype version of the engine first flight-rated in 1954 for installation in the pre-production YF-104.

 General Electric J79 - Wikipedia, the free encyclopedia
Produced by General Electric Aircraft Engines, it was one of the first US-designed engines to outperform designs from the United Kingdom, which had previously led in the jet field.
The J79 was replaced by the late 1960s in new fighter designs by afterburning turbofans such as the TF30 used in the F-111 and F-14, and newer generation turbofans with the PandW F-100 used in the F-15 Eagle which offer better cruise fuel economy by moving unburned air.
In a photo shoot of aircraft with GE jet engines, including the J79, a F-104 collided with one of the few XB-70 test aircraft resulting in a massive crash and fatalities.

The J47 was developed by the General Electric Company from the earlier J35 engine and was first flight-tested in May 1948 as a replacement for the J35 used in the North American XF-86 "Sabre".
General Electric Company (GE) was incorporated in 1892, when it acquired the assets of The Edison General Electric Company, founded by Thomas Alva Edison, and two other electric companies.
In 1903, GE succeeded in installing the world's largest steam turbine generator in Chicago to generate electric power to replace a reciprocating engine that was ten times its size.

In this role the Starfighter served for only a short time, and was generally disliked by the US Air Force, which found its range, load-carrying ability, and equipment inadequate for the service's needs.
They were generally similar to the comparable single-seater, but the additional cockpit required the deletion of the cannon and some internal fuel.
The F-104 was built around the General Electric J79 turbojet engine, fed by side-mounted intakes with fixed inlet scoops and a conical ramp optimized for supersonic speeds.

 General Electric
General Electric's story begins before 1890 when Thomas Edison organized his various businesses into the Edison General Electric Company.
Because of an expertise in power generating gas-turbines, the company was approached by the U.S. Army first in 1917 to develop turbochargers, then again in the 1940's to develop jet engines.
GE got back into the turbojet business with the excellent J47 and has been one of the top aircraft engine companies since.

Their general consensus was that the trend toward ever-increasing weight and complexity had gotten completely out of hand, and they would gladly trade in their existing fighters for a lighter, less costly fighter with clearly superior speed, ceiling, climb rate, and maneuverability.
The seventeen YF-104A service test aircraft were powered by early experimental versions of the General Electric J79 engine instead of the J65 engine which powered the XF-104s.
An investigation later showed that the cause of the crash was a spin that resulted from excessive angle of attack and lack of aircraft response.

F-4 Phantom II Employing sophisticated onboard radar and the AIM-7 Sparrow air-to-air missile, McDonnell's Phantom II design easily met a Navy requirement for a new long-range interceptor and entered Fleet service in 1961.
Powered by a pair of the superb General Electric J79's, the F-4 had a performance envelope that not only fulfilled the Navy's fighter and attack needs, but became the first naval aircraft employed in large numbers by the Air Force.
In combat over Vietnam, however, the Phantom's missile-only armament became a drawback as the large fighter engaged the smaller and more nimble MiG's in close dogfights.
