 General Electric J79 Turbojet   (Site not responding. Last check: 2007-11-05)
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
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 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.

 GE - Aviation: J79 (via CobWeb/3.1 planetlab1.cs.virginia.edu)   (Site not responding. Last check: 2007-11-05)
The J79 was the first GE engine designed with the sophistication provided by already developed and demonstrated components and advanced instrumentation techniques for projecting test performance.
The J79 was placed in a bomb bay of a J47-powered B-45 Tornado.
The J79 was first flown aboard the XF4D and later set a world altitude record at 91,249 feet and a speed record of more than 1,400 miles per hour in a F-104 Starfighter.

 F-16.net :: F-16 Versions - F-16/79
Although the J79 production in the states came to an end in 1979 (13,686 engines built) and the license production in Japan ceased the following year (while production in Israel still continued for use in the Kfir), the GE engine was the obvious choice to power a low-cost, easy-to-maintain export fighter.
As the J79 engine was also 18 inches (46 cm) longer than the F100, the rear fuselage had to be extended.
In order to limit the required changes to a minimum, the front face of the engine compressor was located at almost the exact same position as with the F100 resulting in a lengthening of the fuselageby 18 inches aft of the stabilator pivot point.

 General Dynamics F-16/79 Fighting Falcon
Since the J79 engine required a lower airflow than did the F100 turbofan used on all production F-16A/Bs, the shape of the air intake was altered, with the intake extending further forward than the standard shape and the splitter plate being enlarged.
Since the J79 engine was 18 inches longer than the F100, the rear fuselage had to be extended aft of the stabilator pivot point.
The J79 turbojet ran a lot hotter than the F100 turbofan, so a steel shield weighing about a ton had to be installed around most of the length of the new engine to provide protection from the extra heat.

 IAI F-21 Kfir
In the end, the J79 was selected, not the least because it was the same engine used on the McDonnell Douglas F-4 Phantom II, which the Israelis began to acquire from the United States in 1969, along with a license to produce the J79 themselves.
The J79 was clearly superior to the Atar 09, providing a dry thrust of 49 kN (11,000 lbf) and an afterburning thrust of 83.4 kN (18,750 lbf).
A two-seat Mirage IIIBJ fitted with the GE J79 made its first flight in September 1970, and was soon followed by a re-engined Nesher, which flew in September 1971.

 Kfir
It was apparent that the Atar 09C of the Mirage 5/Nesher had insufficient power, and in 1968 the IAI began to look at alternative powerplants for an upgraded version of the Nesher.
The J79 was eventually selected, primarily because it powered the F-4 Phantom that had just been ordered by the IDF/AF.
The 11 percent greater mass flow of the J79 required the use of larger air intakes, and the higher operating temperatures of the engine required the fitting of extensive heat shielding of the rear fuselage.

 Lockheed YF-104A Starfighter
Fearing that the General Electric J79 turbojet might not be ready in time, the first service test Starfighters were to be powered by the afterburning J65 turbojet.
The seventeen YF-104A service test aircraft (serials 55-2955/2971) were powered by early experimental versions of the General Electric J79 engine instead of the J65 engine which powered the XF-104s.
Together with the first 35 production F-104As, all seventeen YF-104As were used for flight-test and to evaluate early versions of the J79 (the -3, -3A, and -3B) engine, the Vulcan cannon, the AIM-9 (formerly GAR-8) Sidewinder air-to-air missile and the wingtip-mounted fuel tanks.

 The General Dynamics B-58 Hustler   (Site not responding. Last check: 2007-11-05)
The X24A would be produced as the GE J79, which would power many supersonic aircraft, such as the Lockheed F-104 Starfighter and the McDonnell-Douglas F-4 Phantom II.
As it turned out, the J79 was available in time and no B-58 was ever fitted with PandW J57s.
Worse, replacing a panel in the field meant placing the entire aircraft in such a high-precision jig, which made maintenance difficult to say the least, particularly in comparison to other aircraft in the USAF inventory.

 IAI Kfir - Wikipedia, the free encyclopedia
The IAI Kfir is one of the best known examples of the developmental approach to the design and construction of combat aircraft, which consists in the modernization of well-proven airframes to face the challenges posed by an increasingly sophisticated air-combat environment.
Two powerplants were initially selected for trials—the General Electric J79 turbojet and the Rolls-Royce Spey turbofan.
Since the J79 turbojet engine as well as much of the technology inside the Kfir are produced in Israel under U.S. license, all export sales of the Kfir are subject to prior approval from the U.S. State Department, a fact that has limited the sale of the Kfir to foreign nations.

 MILAVIA - Aircraft - IAI Kfir
The Israeli Kfir (kfir is Hebrew for lion cub) is developed for ground attack missions.
IAI combined the delta wing Mirage III/5 airframe with the J79 afterburning turbojet.
Compared to the French Mirage III and Mirage 5 it has a more powerful engine, bigger engine air intakes, a longer nose, revised cockpit, Israeli avionics and systems and a fin air inlet located at the lower front end of the fin.

This was done to ensure that the stabilator remained effective at high angles of attack, while keeping it out of the engine exhaust flow.
A large, fixed, sharp-edged "ramp" or "splitter plate" was installed in front of each inlet, set off from the fuselage about 5 centimeters (2 inches) to ensure that sluggish "boundary layer" air hugging the fuselage stayed out of the inlets.
It is twice the weight of the F-11F Tiger and nearly three times the weight of the A4D Skyhawk, but for all its bulk, it handles better than any modern Navy fighter.

After long delays in gaining US approval to re-export the J79 engine, C2s were sold to Ecuador (12) and Colombia (111).
The development of the IAI Kfir was made possible by Israel's purchase of the F-4 Phantom, and especially its GE J79 engine.
The first J79-engined Mirage was a IIIBJ trainer, and this first flew on 19 October 1970.
