Minsk
Minsk ( be, Мінск ; russian: Минск) is the capital and the largest city of Belarus, located on the Svislach and the now subterranean Niamiha rivers. As the capital, Minsk has a special administrative status in Belarus and is the administrative centre of Minsk Region (voblast) and Minsk District (raion). As of January 2021, its population was 2 million, making Minsk the 11th most populous city in Europe. Minsk is one of the administrative capitals of the Commonwealth of Independent States (CIS) and the Eurasian Economic Union (EAEU). First documented in 1067, Minsk became the capital of the Principality of Minsk before being annexed by the Grand Duchy of Lithuania in 1242. It received town privileges in 1499. From 1569, it was the capital of the Minsk Voivodeship, an administrative division of the Polish–Lithuanian Commonwealth. It was part of a region annexed by the Russian Empire in 1793, as a consequence of the Second Partition of Poland. From 1919 to 1991, aft ...

Tumansky M-90
The Tumansky M-90 was a prototype Soviet radial engine designed before World War II. It proved unreliable and incapable of reaching its designed output and was cancelled in 1944. Development The M-90 began development in the spring of 1939 under the leadership of S. K. Tumansky as a coupled version of the 9-cylinder Gnome-Rhône 9K, which was built under license as the M-75. Later, possibly after E. V. Urmin assumed leadership of the project, the cylinder-piston group of the Tumansky M-88 was adopted, although the cylinder ribbing area was increased.Kotelnikov, p. 156 The layout of the engine was completed by 15 August 1939 and the engineering drawing by 15 October. The first prototype began bench tests on 29 November 1939. A total of five prototypes were built in 1939 and another five in 1940. They could not reach the engine's specified power output and suffered from broken crankshafts, pinion shafts and crankcase In a piston engine, the crankcase is the housing that surro ...

USSR State Prize
The USSR State Prize (russian: links=no, Государственная премия СССР, Gosudarstvennaya premiya SSSR) was the Soviet Union's state honor. It was established on 9 September 1966. After the dissolution of the Soviet Union, the prize was followed up by the State Prize of the Russian Federation. The State Stalin Prize ( Государственная Сталинская премия, ''Gosudarstvennaya Stalinskaya premiya''), usually called the Stalin Prize, existed from 1941 to 1954, although some sources give a termination date of 1952. It essentially played the same role; therefore upon the establishment of the USSR State Prize, the diplomas and badges of the recipients of Stalin Prize were changed to that of USSR State Prize. In 1944 and 1945, the last two years of the Second World War, the award ceremonies for the Stalin Prize were not held. Instead, in 1946 the ceremony was held twice: in January for the works created in 1943–1944 and in June for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumansky R-29
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.Sosounov, V.A.

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-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-15
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. Design and development The R-15-300 was designed at the OKB-300 design bureau led by Sergei Tumansky in the late 1950s. The engine was originally intended for the Tupolev Tu-121 high-altitude high-speed cruise missile. Due to a lack of Soviet resources and funding the engine casing was mainly steel, and in areas exposed to high temperatures, 30 micrometre silver-plated steel. At the time, the USSR did not have the resources to exploit metals such as titanium or other alloys which could have reduced the weight of the engine. The Tu-121 was later canceled, but its basic design was used in the Tupolev Tu-123 reconnaissance drone. Performance The maximum thrust was 7,500 kilograms force (73.5 kN, 16,500 lbf) dry and 11,200 kilograms force (110 kN, 24,700 lbf) with afterburner. This thrust enabled the Mikoyan-Gurevich MiG-25, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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' ...
