The Lyulka AL-21 is an axial flow turbojet engine created by the Soviet Design Bureau named for its chief designer Arkhip Lyulka.
The General Electric/Allison J35 was originally developed by General Electric in parallel with the Whittle-based centrifugal-flow J33, and was the United States Air Force's first axial-flow compressor engine. The J35 was fairly simple, consisting of an eleven-stage axial-flow compressor and a single-stage turbine. With the afterburner, which most models carried, it produced a thrust of 7,400 lbf (32.92 kN).
The Snecma Atar is a French axial-flow turbojet engine built by Snecma. It was derived from the German World War II BMW 018 design, and developed by ex-BMW engineers through a progression of more powerful models. The name is derived from its original design group, Atelier technique aéronautique de Rickenbach near Lindau within the French Occupation Zone of Germany. The Atar powered many of the French post-war jet aircraft, including the Vautour, Étendard and Super Étendard, Super Mystère and several models of the Mirage.
The Tumansky R-11 was a Soviet Cold War-era turbojet engine.
The Tumansky R-13 is a Soviet turbojet engine designed by Sergei Alekseevich Gavrilov.
The Tumansky R-25 is a turbojet engine, which is seen as the ultimate development of Tumansky R-11. It was designed under the leadership of Sergei Alekseevich Gavrilov.
The Lyulka AL-7 was a turbojet designed by Arkhip Mikhailovich Lyulka and produced by his Lyulka design bureau. The engine was produced between 1954 and 1970.
The Tumansky RD-9 was an early Soviet turbojet engine, not based on pre-existing German or British designs. The AM-5, developed by scaling down the AM-3, was available in 1952 and completed testing in 1953; it produced 25.5 kN (5,700 lbf) thrust without afterburner. AM-5 engine is notable for making the first Soviet supersonic interceptor possible, the MiG-19 and the first all-weather area interceptor, the Yak-25. When Sergei Tumansky replaced Alexander Mikulin as the OKB-24's chief designer in 1956, the engine was renamed RD-9. The engine was later built under license in China as the WP-6.
The Tumansky R-15 is an axial flow, single shaft turbojet with an afterburner. Its best known use is on the Mikoyan-Gurevich MiG-25.
The Allison J71 was a single spool turbojet engine, designed and built in the United States. It began development in 1948 as a much modified J35, originally designated J35-A-23.
The General Electric YJ93 turbojet engine was designed as the powerplant for both the North American XB-70 Valkyrie bomber and the North American XF-108 Rapier interceptor. The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent/divergent exhaust nozzle. The maximum sea-level thrust was 28,800 lbf (128 kN).
The General Electric GE4 turbojet engine was designed in the late 1960s as the powerplant for the Boeing 2707 supersonic transport. The GE4 was a nine-stage, single-shaft, axial-flow turbojet based largely on the General Electric YJ93 which powered the North American XB-70 bomber. The GE4 was the most powerful engine of its era, producing 50,000 lbf (220 kN) dry, and 65,000 lbf (290 kN) with afterburner. The Boeing 2707 was cancelled in 1971, putting an end to further work on the GE4.
The General Electric J73 turbojet was developed by General Electric from the earlier J47 engine. Its original USAF designation was J47-21, but with innovative features including variable inlet guide vanes, double-shell combustor case, and 50% greater airflow was redesignated J73. Its only operational use was in the North American F-86H.
The Mikoyan-Gurevich Ye-8 was a supersonic jet fighter developed in the Soviet Union, intended to replace the MiG-21. Only two prototypes were built in 1960-61. The original MiG-21's air intakes were moved under the fuselage, freeing up the nose where a larger and more powerful radar, able to deliver longer range air-to-air missiles, could be built in. Canards were built to both sides of the nose, in front of the cockpit,.
The Lyulka TR-1 was a turbojet designed by Arkhip Lyulka and produced by his Lyulka design bureau. It was the first indigenous Soviet jet engine.
The Lyulka AL-5 was a Soviet axial compressor turbojet developed from the Lyulka TR-3 turbojet around 1950. It was flight-tested in a number of prototype aircraft, but was not accepted for production.
The Mikoyan-Gurevich I-75 was the final design of a series of three experimental swept-wing interceptors developed in the Soviet Union in the mid-late 1950s by the Mikoyan-Gurevich design bureau from their Mikoyan-Gurevich I-3 airframe. All the aircraft in the I-3 program were affected by delays in the development of the Klimov VK-3 turbojet engine, its cancellation and ultimate replacement by the Lyulka AL-7F turbojet engine.
The Tumansky R-29 is a Soviet turbojet aircraft engine that was developed in the early 1970s. It is generally described as being in the "third generation" of Soviet gas turbine engines which are characterized by high thrust-to-weight ratios and the use of turbine air cooling.
The Klimov VK-3 was the first Soviet afterburning bypass turbojet engine. Designed by S V Lyunevich at Klimov, at OKB-117 in 1949, this engine first ran in 1952, and was qualified at 5,730 kg (12,632 lb) thrust (dry) and 8,440 kg (18,607 lb) thrust in 1954. The VK-3 was developed for the Mikoyan-Gurevich I-3 (I-380) and I-3U/I-5 (I-410) fighters. First flown in the I-3U in July 1956, the engine's performances was good but its reliability was poor. Even after modifications in December 1956 when newly designed compressor blades were installed, developmental problems continued, the program was ultimately canceled in January 1958. The engine was superseded by the Lyulka AL-7F, a less modern but more efficient engine.
Note: Not to be confused with the Mikoyan-Gurevich MiG-23, which was a completely different aircraft, though designed to fulfil the same specification.
