The General Electric J79 is an axial-flow turbojet engine built for use in a variety of fighter and bomber aircraft and a supersonic cruise missile. The J79 was produced by General Electric Aircraft Engines in the United States, and under license by several other companies worldwide.
The YJ93 started life as the General Electric J79-X275, an enlarged version of the General Electric J79 turbojet with "275" meaning Mach 2.75, the engine's target operating speed. [2] This design evolved into the X279 when Mach 3 cruise became a requirement, and ultimately became the YJ93. [3] The engine used a special high-temperature JP-6 fuel.
Two widely spaced General Electric J79 turbojet engines were supplied with air through inlets with variable intake ramps. [ 3 ] [ 14 ] While the same engine was used by several other US military aircraft, such as the Convair B-58 Hustler and the McDonnell Douglas F-4 Phantom II , the powerplants used on the A-5 differed in some ways, such as ...
The Pratt & Whitney J75 (civilian designation: JT4A) is an axial-flow turbojet engine first flown in 1955. A two-spool design in the 17,000 lbf (76 kN) thrust class, the J75 was essentially the bigger brother of the Pratt & Whitney J57 (JT3C).
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
The LM1500 was derived from the J79 engine in 1960. [3] Its first application was for the first US sea-going research hydrofoil, HS Denison. [1] Conversion as a marinised turboshaft engine involved two major changes: the addition of a free power turbine, and corrosion-protection by the addition of internal coatings and a maintenance scheme of freshwater rinsing to prevent salt damage.
The General Electric CJ805 is a jet engine which was developed by General Electric Aircraft Engines in the late 1950s. It was a civilian version of the J79 and differed only in detail. [ 1 ] It was developed in two versions.
The principal difference of this derivative was the replacement of the Atar engine by an Israeli-built General Electric J79 engine. The J79 was a popular American engine for combat aircraft, having already been used on fighters such as the Lockheed F-104 Starfighter and the McDonnell Douglas F-4 Phantom II.
