Soloviev D-25
The Soloviev D-25V is a Soviet gas-turbine turboshaft engine for use in large helicopters. Designed and originally manufactured by the Soloviev Design Bureau the engine has been in production since May 1960. The power unit consists of two engines coupled to a gearbox weighing 3,200 kg (7,050 lb). The ''V'' in the designation means ''vertoletny'' (russian: Вертолетный), for helicopters.

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaftpower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbines, a gear reduction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soloviev Design Bureau
UEC-Aviadvigatel JSC (Russian: АО "ОДК-Авиадвигатель", lit. Aeroengine) is a Russian developer and builder of aircraft engines, most notably jet engines for commercial aircraft. Based at the Perm Engine Plant, its products power the Ilyushin Il-76MF, Ilyushin Il-96, Tupolev Tu-204, and Tupolev Tu-214. It also designs and builds high-efficiency gas turbine units for electric power stations and for gas pumping plants. The company has its background in the Experimental Design Bureau-19 plant, set up to manufacture aircraft engines. History Foundation and Shvetsov era Aviadvigatel can be traced back to the engine design and manufacturing factory (Plant No.19) founded in Perm Krai, Russian Soviet Republic, on 1 June 1934, to produce the Wright Cyclone-derived Shvetsov M-25. Arkadiy Shvetsov was named chief designer at the plant, which was also referred to as the ''Perm Design/Engine School''. The school was given the Soviet Experimental Design Bureau designati ...

Mil Mi-6
The Mil Mi-6 (NATO reporting name Hook), given the article number ''izdeliye 50'' and company designation V-6, is a Soviet/Russian heavy transport helicopter that was designed by the Mil design bureau. It was built in large numbers for both military and civil roles and used to be the largest helicopter in production until Mil Mi-26 was put in production in 1980. Design and development The Mi-6 resulted from a joint civil-military requirement for a very large vertical-lift aircraft, which could be used to add mobility in military operations as well as assist in the exploration and development of the expansive central and eastern regions of the USSR. Flown for the first time on 5 June 1957, the Mi-6 was the first Soviet turboshaft-powered production helicopter. The R-7 gearbox and rotor head developed for the project have a combined weight of 3200 kg, which is greater than the two turboshaft engines. Variable-incidence winglets were first mounted on the craft's sides in 1960 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kamov Ka-22
The Kamov Ka-22 ''Vintokryl'' (rotor-wing, or literally, (air)screw-wing) ( Cyrillic:Камов Ка-22 Винтокрыл) ( NATO reporting name: Hoop) was a rotorcraft developed by Kamov for the Soviet Air Force. The experimental transport aircraft combined the capabilities of a helicopter for vertical take-off and landing with those of a fixed-wing aircraft for cruise. The Ka-22 carried a large payload, having a hold comparable in size to the Antonov An-12. Eight world records for altitude and speed were set by the Ka-22 in its class, none of which have since been broken."Helicopter Ka-22." ''Kamov Company.'' Retrieved: 5 June 2008.

Mil Mi-10
The Mil Mi-10 (NATO reporting name Harke), given the product number ''izdeliye 60'', is a Soviet military transport helicopter of flying crane configuration, developed from the Mi-6, entering service in 1963. While most versions had been retired by 2009, the short-legged Mi-10K was still in service as of 2014. Design and development The advent of the Mi-6 gave the Soviet Union the very useful ability to move and place large, bulky or heavy loads with precision. Limitations of the Mi-6 in the flying crane role included a weight to payload ratio and the inability of the crew to easily see the load and its intended final position. A Council of Ministers directive of 20 February 1958 tasked OKB-329 (OKB Mil) with the development of a dedicated flying crane helicopter for carrying bulky loads unable to be carried in the hold of an Mi-6. The Mil OKB's response drew heavily on the Mi-6, utilising the dynamic components and Soloviev D-25V turboshaft engines, on a slim fuselage sitti ...

Mil V-12
The Mil V-12 (NATO reporting name: Homer), given the project number ''Izdeliye 65'' ("Item 65"), is the largest helicopter ever built. The designation "Mi-12" would have been the name for the production helicopter and was not applied to the V-12 prototypes. Design and development Design studies for a giant helicopter were started at the Mil OKB in 1959, receiving official sanction in 1961 by the GKAT (''Gosudarstvenny Komitet po Aviatsionnoy Tekhnike'' - State Committee on Aircraft Technology) instructing Mil to develop a helicopter capable of lifting . The GKAT directive was followed by a more detailed specification for the V-12 with hold dimensions similar to the Antonov An-22, intended to lift major items of combat materiel as well as 8K67, 8K75 and Proton (rocket family), 8K82 inter-continental ballistic missiles (ICBM). Design limitations forced Mil to adopt a twin rotor system but design studies of a tandem layout, similar to the Boeing CH-47 Chinook, revealed major proble ...

Yakovlev Yak-60
Yakovlev Yak-60 (known as Yak-32 in some sources) is the possible designation for an experimental Yakovlev tandem-rotor heavy-lift helicopter design of the late 1960s. This design never progressed beyond the model stage. Development This helicopter was designed in the late 1960s, and may have been a competing design to the Mil Mi-12 heavy lift helicopter. It featured two Mil Mi-6 rotors in tandem, each driven by a pair of Soloviev D-25VF engines, potentially giving it four times the payload capacity of the Boeing CH-47 Chinook. The cockpit would have been similar to that of the Yakovlev Yak-24. Compared to the radical Mi-12, the Yak-60 design was far more conventional, though two Mi-12s were produced and no Yak-60s. It has been suggested that the designation Yak-60 was based on an extant study model which had the number "60" painted prominently on its side.

Jet A
Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. Furthermore, the range of molecular mass between hydrocarbons (or different carbon numbers) is defined by the requirements for the product, such as the freezing point or smoke point.
