Tupolev Tu-22
The Tupolev Tu-22 ( NATO reporting name: Blinder) was the first supersonic bomber to enter production in the Soviet Union. Manufactured by Tupolev, the Tu-22 entered service with the Soviet military in the 1960s. The aircraft was a disappointment, lacking both the speed and range that had been expected. It was also a difficult design to fly and maintain. It was produced in small numbers, especially compared to the Tupolev Tu-16 it was designed to replace. The aircraft was later adapted for other roles, notably as the Tu-22R reconnaissance aircraft and as carriers for the long-range Kh-22 anti-shipping missile, antiship missile. Tu-22s were sold to other nations, including Libyan Arab Jamahiriya, Libya and Ba'athist Iraq, Iraq. The Tu-22 was one of the few Soviet jet bombers to see combat: Libyan Tu-22s were used Uganda–Tanzania War, against Tanzania Chadian–Libyan conflict, and Chad, and Iraqi Tu-22s were used during the Iran–Iraq War.

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Rybinsk
Rybinsk ( rus, Рыбинск, p=ˈrɨbʲɪnsk), the second largest types of inhabited localities in Russia, city of Yaroslavl Oblast in Russia, lies at the confluence of the Volga River, Volga and Sheksna Rivers, 267 kilometers north-north-east of Moscow. Population: It was previously known as ''Ust-Sheksna'' (until 1504), ''Rybnaya Sloboda'' (until 1777), ''Shcherbakov'' (1946–1957), and ''Andropov'' (1984–1989). History Early history Rybinsk is one of the oldest Slavic settlements on the Volga River. The place was first recorded by chroniclers in 1071 as Ust-Sheksna, i.e. "the mouth of the Sheksna". During this period the settlement was a regional center for craft and metal based produce and for trade. In the mid-13th century, Ust-Sheksna was laid waste by Mongol invasion of Rus', invading Mongols. For the next few centuries, the settlement was referred to alternatively as Ust-Sheksna or Rybansk. From 1504, it was identified in documents as Rybnaya Sloboda (literally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myasishchev M-50
The Myasishchev M-50 (russian: Мясищев М-50; NATO reporting name Bounder) is a Soviet prototype four-jet engine supersonic strategic bomber which never attained service. Only one flightworthy prototype was built, which was first flown in October 1959. The M-50 was constructed by the Myasishchev design bureau. Design and development The M-50 was a fast jet bomber with four engines: two Dobrynin VD-7 non-afterburning turbojet engines at the outer and two VD-7F afterburning turbojet engines at the inner positions. The two inner engines were located under the wing, and the two outer on the wingtips of its shoulder-mounted, truncated delta wings. The second aircraft was designated M-52 and carried Zubets 16-17 turbofans, around which the aircraft had been designed. The engine installation was modified, and a second tailplane added to the top of the fin. The fore-end of the M-52 has been redesigned: in place of the tandem cockpit of the M-50 with seats in a row, the M-52 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Myasishchev M-4
The Myasishchev M-4 ''Molot'' (russian: Молот (Hammer), USAF/DoD reporting name "Type 37", ASCC reporting name Bison) was a four-engined strategic bomber designed by Vladimir Mikhailovich Myasishchev and manufactured by the Soviet Union in the 1950s to provide a Long Range Aviation bomber capable of attacking targets in North America. The aircraft fell quite short of its intended range and was not really capable of attacking the most valuable targets in the United States. As this became clear, production was shut down. In spite of the failure to produce a capable strategic design and the resulting small numbers, the M-4 nevertheless sparked fears of a "bomber gap" when 18 of the aircraft were flown in a public demonstration on May Day in 1954. The US responded by building hundreds of Boeing B-47s and B-52s to counter this perceived threat. The design was updated with more efficient engines, inflight refuelling support and the removal of the glass nose for optical bombing a ...

Myasishchev VM-T
The Myasishchev VM-T ''Atlant'' (Russian: ''Мясищев ВМ-Т «Атлант»'' ( "Atlas"), with the "VM-T" ("BM-T") standing for Vladimir MyasishchevTransport) was a variant of Myasishchev's M-4 ''Molot'' bomber (the "3M"), re-purposed as a strategic-airlift airplane. The VM-T was modified to carry rocket boosters and the Soviet space shuttles of the ''Buran'' program. It is also known as the 3M-T. Design and development The design was conceived in 1978 when Myasishchev was asked to solve the problem of transporting rockets and other large space vehicles to the Baikonur Cosmodrome. Engineers used an old 3M (a modified M-4 bomber) and replaced the empennage with dihedralled horizontal stabilizers with large, rectangular end-plate tailfins to accommodate payloads measuring as large as twice the diameter of the aircraft's fuselage. A large, aerodynamically optimized cargo container, placed on top of the aircraft, would contain the freight. In addition, a new control sy ...

Caspian Sea Monster
The KM (Korabl Maket) (Russian: Корабль-Макет, literally "Ship-maquette" or "Model-Ship"), known colloquially as the Caspian Sea Monster, was an experimental ground effect vehicle developed in the Soviet Union in the 1960s by the Central Hydrofoil Design Bureau. The KM began operation in 1966, and was continuously tested by the Soviet Navy until 1980 when it crashed into the Caspian Sea. The KM was the largest and heaviest aircraft in the world from 1966 to 1988, and its surprise discovery by the United States and the subsequent attempts to determine its purpose became a distinctive event of espionage during the Cold War. Design and development The KM was an experimental aircraft developed from 1964 to 1966, during a time when the Soviet Union saw interest in ground effect vehicles—airplane-like vehicles that use ground effect to fly several meters above surfaces, primarily bodies of water (such as the Caspian Sea). It was designed at the Central Hydrofoil Des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kilogram-force
The kilogram-force (kgf or kgF), or kilopond (kp, from la, pondus, lit=weight), is a non-standard gravitational metric unit of force. It does not comply with the International System of Units (SI) and is deprecated for most uses. The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). That is, it is the weight of a kilogram under standard gravity. Therefore, one kilogram-force is by definition equal to .NISTbr>''Guide for the Use of the International System of Units (SI)''Special Publication 811, (1995) page 51 Similarly, a gram-force is , and a milligram-force is . Kilogram-force is a non-standard unit and is classified in the International System of Units (SI) as a unit that is not accepted for use with SI.
