Antonov An-225 Mriya
The Antonov An-225 Mriya (; NATO reporting name: Cossack) was a large strategic airlift cargo aircraft designed and produced by the Antonov Design Bureau in the Soviet Union. It was originally developed during the 1980s as an enlarged derivative of the Antonov An-124 airlifter for transporting ''Buran'' spacecraft. On 21 December 1988, the An-225 performed its maiden flight; only one aircraft was ever completed, although a second airframe with a slightly different configuration was partially built. After a brief period of use in the Soviet space programme, the aircraft was mothballed during the early 1990s. Towards the turn of the century, it was decided to refurbish the An-225 and reintroduce it for commercial operations, carrying oversized payloads for the operator Antonov Airlines. Multiple announcements were made regarding the potential completion of the second airframe, though its construction largely remained on hold due to a lack of funding. By 2009, it had reportedl ...

Aircraft Boneyard
An aircraft boneyard or aircraft graveyard is a storage area for aircraft which are retired from service. Most aircraft at boneyards are either kept for storage continuing to receive some maintenance or parts of the aircraft are removed for reuse or resale and the aircraft are scrapped. Boneyard facilities are generally located in deserts such as those in the southwestern United States, since the dry conditions reduce corrosion and the hard ground does not need to be paved. In some cases, aircraft which were planned to be scrapped or were stored indefinitely without plans of ever returning to service were brought back into service, as the aviation market or the demands of military aviation changed or failed to develop as was anticipated. Some yards are privately owned and operated, others belong to the military including the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan Air Force Base in Tucson, Arizona. After aircraft are put into boneyards, many are st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Space Program
The Soviet space program () was the state space program of the Soviet Union, active from 1951 until the dissolution of the Soviet Union in 1991. Contrary to its competitors (NASA in the United States, the European Space Agency in Western Europe, and the Ministry of Aerospace Industry in China), which had their programs run under single coordinating agencies, the Soviet space program was divided between several internally competing OKB, design bureaus led by Sergei Korolev, Korolev, Kerim Kerimov, Kerimov, Mstislav Keldysh, Keldysh, Mikhail Yangel, Yangel, Valentin Glushko, Glushko, Vladimir Chelomey, Chelomey, Viktor Makeyev, Makeyev, Boris Chertok, Chertok and Information Satellite Systems Reshetnev, Reshetnev. Several of these bureaus were subordinated to the Ministry of General Machine-Building. The Soviet space program served as an important marker of claims by the Soviet Union to its superpower status.

Buran Programme
The ''Buran'' programme (, , "Snowstorm", "Blizzard"), also known as the "VKK Space Orbiter programme" (), was a Soviet and later Russian reusable spacecraft project that began in 1974 at the Central Aerohydrodynamic Institute in Moscow and was formally suspended in 1993. In addition to being the designation for the whole Soviet/Russian reusable spacecraft project, ''Buran'' was also the name given to orbiter 1K, which completed one uncrewed spaceflight in 1988 and was the only Soviet reusable spacecraft to be launched into space. The Buran-class orbiters used the expendable Energia rocket as a launch vehicle. The Buran programme was started by the Soviet Union as a response to the United States Space Shuttle program and benefited from extensive espionage undertaken by the KGB of the unclassified US Space Shuttle program, resulting in many superficial and functional similarities between American and Soviet Shuttle designs. Although the Buran class was similar in appearance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenit (rocket Family)
Zenit (, ; meaning ''Zenith'') was a family of space launch vehicles designed by the Yuzhnoye Design Bureau in Dnipro, Ukraine, which was then part of the Soviet Union. Zenit was originally built in the 1980s for two purposes: as a liquid rocket booster for the Energia (rocket), Energia rocket and, equipped with a second stage, as a stand-alone middle-weight launcher with a payload greater than the 7 tonnes of the Soyuz (rocket), Soyuz but smaller than the 20 tonnes payload of the Proton (rocket family), Proton. The last rocket family developed in the USSR, the Zenit was intended as an eventual replacement for the dated Soyuz and Proton families, and it would employ propellants which were safer and less toxic than the Proton's nitrogen tetroxide/UDMH mix. Zenit was planned to take over crewed spaceship launches from Soyuz, but these plans were abandoned after the dissolution of the Soviet Union in 1991. Many of components of the Zenit rockets were produced in Russia. The Ukraini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energia (rocket)
Energia (; GRAU 11K25) was a 1980s super-heavy lift launch vehicle. It was designed by NPO Energia of the Soviet Union as part of the Buran programme, Buran program for a variety of payloads including the Buran (spacecraft), Buran spacecraft. Control system main developer enterprise was the Khartron NPO "Electropribor". The Energia used four strap-on boosters each powered by a four-chamber RD-170 engine burning kerosene/Liquid oxygen, LOX, and a central core stage with four single-chamber RD-0120 (11D122) engines fueled by liquid hydrogen/LOX. The launch vehicle had two functionally different operational variants: Energia-Polyus, the initial test configuration, in which the Polyus (spacecraft), Polyus system was used as a final stage intended to put the payload into orbit, and Energia-Buran, in which the Buran programme, ''Buran'' orbiter was the payload and the source of the orbit insertion impulse. The launch vehicle had the capacity to place about 100 tonnes in Low Earth orbit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shuttle Carrier Aircraft
The Shuttle Carrier Aircraft (SCA) are two extensively modified Boeing 747 airliners that NASA used to transport Space Shuttle orbiters. One (N905NA) is a 747-100 model, while the other (N911NA) is a short-range 747-100SR. Both are now retired. The SCAs were used to ferry Space Shuttles from landing sites back to the Shuttle Landing Facility at the Kennedy Space Center. The orbiters were placed on top of the SCAs by Mate-Demate Devices, large Gantry crane, gantry-like structures that hoisted the orbiters off the ground for post-flight servicing then mated them with the SCAs for ferry flights. In approach and landing tests, approach and landing test flights conducted in 1977, the Space Shuttle Enterprise, test shuttle ''Enterprise'' was released from an SCA during flight and glided to a landing under its own control. Design and development The Lockheed C-5 Galaxy was considered for the shuttle-carrier role by NASA but rejected in favor of the 747. This was due to the 747's lo ...

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 dihedrall horizontal stabilizers having 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 contro ...

Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover (locomotive), power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel–electric locomotives and diesel–hydraulic. Early internal combustion engine, internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low-power gasoline engines could be coupled to mechanical transmission (mechanics), transmissions, the more powerful diesel engines required the development of new forms of transmiss ...
