The Tumansky R-11 (initially AM-11) is a Soviet Cold War-era turbojet engine.
The Tumansky R-11 was developed by A.A. Mikulin, Sergei Tumansky, and B.S. Stechkin as a twin-spool axial-flow high-altitude non-afterburning turbojet for Yakovlev Yak-25RV reconnaissance aircraft. This engine was the first Soviet twin-spool turbojet. It was first run in early 1956 [1] and was later employed in some variants of the Yakovlev Yak-26 and Yakovlev Yak-27, as well as the Yak-28. [2] The R-11's basic design was very successful and it was later developed into the Tumansky R-13 and Tumansky R-25 along with the experimental Tumansky R-21. A total of 20,900 R-11 engines were built.
The Pratt & Whitney J57 is an axial-flow turbojet engine developed by Pratt & Whitney in the early 1950s. The J57 was the first 10,000 lbf (45 kN) thrust class engine in the United States. It was also the first two-spool turbojet to run, a few months before the similar Bristol Olympus in the UK.
The Yakovlev Yak-28 is a swept wing, turbojet-powered combat aircraft used by the Soviet Union. Produced initially as a tactical medium bomber, it was also manufactured in reconnaissance, electronic warfare, interceptor, and trainer versions, known by the NATO reporting names Brewer, Brewer-E, Firebar, and Maestro respectively. Based on the Yak-129 prototype first flown on 5 March 1958, it began to enter service in 1960.
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 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. Among its major uses was the Lockheed F-104 Starfighter, Convair B-58 Hustler, McDonnell Douglas F-4 Phantom II, North American A-5 Vigilante and IAI Kfir.
The General Electric/Allison J35 was the United States Air Force's first axial-flow compressor jet engine. Originally developed by General Electric in parallel with the Whittle-based centrifugal-flow J33, the J35 was a fairly simple turbojet, 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 (33 kN).
The Rolls-Royce Avon was the first axial flow jet engine designed and produced by Rolls-Royce. Introduced in 1950, the engine went on to become one of their most successful post-World War II engine designs. It was used in a wide variety of aircraft, both military and civilian, as well as versions for stationary and maritime power.
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 General Electric J85 is a small single-shaft turbojet engine. Military versions produce up to 3,500 lbf (16 kN) of thrust dry; afterburning variants can reach up to 5,000 lbf (22 kN). The engine, depending upon additional equipment and specific model, weighs from 300 to 500 pounds. It is one of GE's most successful and longest in service military jet engines, with the civilian versions having logged over 16.5 million hours of operation. The United States Air Force plans to continue using the J85 in aircraft through 2040. Civilian models, known as the CJ610, are similar but supplied without an afterburner and are identical to non-afterburning J85 variants, while the CF700 adds a rear-mounted fan for improved fuel economy.
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. The AM-5 engine is notable for making possible the first mass-produced supersonic interceptors such as the MiG-19, and the first Soviet 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 General Electric CJ610 is a non-afterburning turbojet engine derived from the military J85, and is used on a number of civilian business jets. The model has logged over 16.5 million hours of operation. Civilian versions have powered business jets such as the Learjet 23 and the Hamburger Flugzeugbau HFB 320 Hansa Jet. The engines are also used in the flyable Messerschmitt Me 262 reproductions built by the Me 262 Project in the United States.
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 Kuznetsov NK-32 is an afterburning three-spool low bypass turbofan jet engine which powers the Tupolev Tu-160 supersonic bomber, and was fitted to the later model Tupolev Tu-144LL supersonic transport. It produces 245 kN (55,000 lbf) of thrust in afterburner.
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 Yakovlev Yak-140 was a Soviet prototype lightweight supersonic fighter developed during the 1950s. The prototype was completed in 1954, but it was denied authorization to enter flight testing and the program was cancelled in 1956.
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 Tumansky R-21 was a Soviet turbojet engine of the 1960s. Used for development only, the project was canceled.
