Tumansky R-11F
The Tumansky R-11 (initially AM-11) was a Soviet Cold War-era turbojet engine. Design and development 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 1956Gunston 1989, p.167. and was later employed in some variants of the Yakovlev Yak-26 and Yakovlev Yak-27, as well as the Yak-28.Goebel, Greg"The Yakovlev Yak-25 & Yak-28."AirVectors. Retrieved: 17 July 2012. 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. Variants * R-11V-300 - first production version, high-altitude, non-afterburning * R-11F-300 (R-37F) - afterburning version, entered production in 1956, used on MiG-21F, P and U. * R-11AF-300 - impr ...

Yakovlev Yak-25
The Yakovlev Yak-25 ( NATO designation Flashlight-A/Mandrake) was a swept wing, turbojet-powered interceptor and reconnaissance aircraft built by Yakovlev and used by the Soviet Union. Design and development The Yak-25 originated from a need for long-range Interceptor aircraft to protect the USSR's northern and eastern territory. The specification for a two-seat, twin-engine jet fighter and a related reconnaissance aircraft was issued by Joseph Stalin on 6 August 1951. Yak-120 Yakovlev began developing a two-seat, twin-engine patrol interceptor, designated the Yak-120 by the design bureau, in 1951. It received official authorization by a directive of the Council of Ministers on 10 August of that year. In a break from previous Yakovlev designs, the Yak-120's thin, mid-set wings were swept back at a 45 degree angle with large two-section flaps. To provide more directional stability, a ventral fin was attached below the swept cruciform tail. The aircraft was powered by two Miku ...

Axial Compressor
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MiG-21
The Mikoyan-Gurevich MiG-21 (russian: Микоян и Гуревич МиГ-21; NATO reporting name: Fishbed) is a supersonic jet fighter and interceptor aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. Its nicknames include: "balalaika", because its planform resembles the stringed musical instrument of the same name; "''Ołówek''", Polish for "pencil", due to the shape of its fuselage, and "''Én Bạc''", meaning "silver swallow", in Vietnamese. Approximately 60 countries across four continents have flown the MiG-21, and it still serves many nations six decades after its maiden flight. It set aviation records, becoming the most-produced supersonic jet aircraft in aviation history, the most-produced combat aircraft since the Korean War and, previously, the longest production run of any combat aircraft (now exceeded by both the McDonnell Douglas F-15 Eagle and General Dynamics F-16 Fighting Falcon).

Tumansky R-21
The Tumansky R-21 was a Soviet turbojet engine of the 1960s. Used for development only, the project was canceled. Design and development The Tumansky R-21 was developed at Tushino motor plant (part of OKB-300), headed by Nikolai Georgievich Metskhvarishvili, as a twin-spool axial-flow afterburning turbojet. It was based on the Tumansky R-11 with the goal of increasing thrust and airflow, using a new six-stage compressor with a larger diameter and different rotor blades than its predecessor as well as a new afterburner chamber and variable exhaust nozzle. The increased pressure ratio and turbine inlet temperature required components to be fabricated from advanced alloys. Several contemporary Soviet aircraft were planned to use the R-21, including the Sukhoi T-58, Sukhoi T-6 and the Mikoyan-Gurevich Ye-8. On September 11, 1962 an R-21, fitted to a Ye-8, exploded in mid-air after compressor failure; test pilot Georgy Mosolov survived the ejection at Mach 1.78, but he never ful ...

Tumansky R-25
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. Design and development The Tumansky R-25 was designed as a replacement for Tumansky R-13 in MiG-21 fighters. R-25 is a two-spool axial-flow turbojet featuring a new compressor with increased overall pressure ratio and airflow, variable two-stage afterburner, and greater use of titanium. The R-25 jet engine's specialty was the addition of a second fuel pump in the afterburning stage. Activating the ЧР (rus. "чрезвычайный режим" - emergency mode) booster feature allows the engine to develop of thrust under of altitude. The limit of operation is 2 minutes in practice and in war, as further use causes the engine to overheat and potentially explode. Use of EPR requires engine take-out inspection upon landing and every minute of its use counts as one full hour of engine runtime on the logbook. Th ...

Tumansky R-13
The Tumansky R-13 is a Soviet turbojet engine designed by Sergei Alekseevich Gavrilov. Design and development The Tumansky R-13 is a development of the successful Tumansky R-11 engine. It is a two-spool axial-flow turbojet featuring a new five-stage high-pressure compressor, new combustion chamber design to facilitate restarting the engine at high altitudes, new afterburner, and greater use of titanium components. It is used by MiG-21M, MF, SM, and SMT, and Sukhoi Su-15M and TM. R-13 is also built in China as LM WP13, and experienced similar fate like Tumansky R-11: originally, both were licensed to be built in China, but after the Sino-Soviet split all Soviet technical support was withdrawn and Chinese proceeded on their own. Under the leadership of the general designer Jiang Hepu (江和甫), both R-11 and R-13 were successfully built in China. The R-95 is a non-afterburning development of this engine used by initial versions of the Sukhoi Su-25 The Sukhoi Su-25 ''Grach' ...

Yakovlev Yak-28
The Yakovlev Yak-28 (russian: Яковлев Як-28) is a swept wing, turbojet-powered combat aircraft used by the Soviet Union. Produced initially as a tactical 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. Design and development The Yak-28 was firstTaylor 1976, pp. 520–521. seen by the West at the Tushino air show in 1961. Western analysts initially believed it to be a fighter rather than an attack aircraft—and a continuation of the Yak-25M—and it was designated "Flashlight". After its actual role was realized, the Yak-28 bomber series was redesignated "Brewer". The Yak-28 had a large mid-mounted wing, swept at 45 degrees. The tailplane set halfway up the vertical fin (with cutouts to allow rudder movement). Slats were fitted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakovlev Yak-27
The Yakovlev Yak-27 (NATO reporting name "Flashlight-C") was a family of Soviet supersonic aircraft developed in 1958 from the Yak-121 prototype. The most built variant was the tactical reconnaissance Yak-27R (NATO reporting name "Mangrove"). Design and development The Yak-121 prototype was developed as a successor to the Yak-25 family and it became the base for the Yak-27 family of supersonic interceptor and tactical reconnaissance aircraft. The Yak-27 and Yak-27K interceptors, armed with guns and K-8 missiles respectively, reached or exceeded their requirements, but were overtaken in performance by the Sukhoi Su-9, and so production was not authorized. A high-altitude interceptor version, the Yak-27V, was converted from the Yak-121 prototype by fitting a 1,300 kg•f (2,866 lb•f) Dushkin S-155 rocket booster in the rear fuselage, and Tumansky RD-9AKYe afterburning turbojets. Although performance was very good, reaching the height of 23,000 m (75,400 ft) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakovlev Yak-26
The Yakovlev Yak-26, OKB designation Yak-123, was a Soviet tactical supersonic bomber aircraft flown at the Tushino air show on 24 June 1956. The model did not enter service. Design and development The Yak-123-1 prototype was developed from the subsonic Yak-25, and in parallel with the Yak-27 aircraft family, with the main goal of operating at supersonic speed. Although the Yak-123 kept the Yak-25's layout, it had a more streamlined and longer fuselage with a glazed nose for a navigator-bombardier, replacing the Yak-25's radome. The engines were upgraded to the much more powerful RD-9AK afterburning turbojets and the wings modified. The Nudelman N-37 cannon was replaced with two NR-23 23 mm guns. The next prototype, designated Yak-26-3, had a tail barbette with two more such guns, but it was removed altogether after testing. An internal weapons bay was added for of bombs, including the nuclear RDS-4 ''Tatyana''. Additional bombs could be carried on underwing pylons. Engin ...
