Buran Space Shuttle
''Buran'' (russian: Буран, , meaning "Snowstorm" or "Blizzard"; GRAU index serial number: 11F35 1K, construction number: 1.01) was the first spaceplane to be produced as part of the Soviet/Russian Buran program. Besides describing the first operational Soviet/Russian shuttle orbiter, "Buran" was also the designation for the entire Soviet/Russian spaceplane project and its orbiters, which were known as "Buran-class orbiters". Buran completed one uncrewed spaceflight in 1988, and was destroyed in the 2002 collapse of its storage hangar. The Buran-class orbiters used the expendable Energia rocket, a class of super heavy-lift launch vehicle. It is named after the Asian wind. Construction The construction of the Buran spacecraft began in 1980, and by 1984 the first full-scale orbiter was rolled out. Over 1000 companies all over the Soviet Union were involved in construction and development. The Buran spacecraft was made to be launched on the Soviet Union's super-heavy lif ...

Buran Programme
The ''Buran'' program (russian: Буран, , "Snowstorm", "Blizzard"), also known as the "VKK Space Orbiter program" (russian: ВКК «Воздушно-Космический Корабль», lit=Air and Space Ship), 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 K1, 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. Unlike the Space Shuttle, Buran had a capability of flying uncrewed missions, as well as performing fully automated landings. The Buran program was started by the Soviet Union as a response to the United States Space Shuttle program. The project was the l ...

Kristall
The Kristall (russian: Кристалл, , Crystal) (77KST, TsM-T, 11F77T) module was the fourth module and the third major addition to ''Mir''. As with previous modules, its configuration was based on the 77K (TKS) module, and was originally named "Kvant 3". It was launched on May 31, 1990 on Proton-K. It docked to Mir autonomously on June 10, 1990. Description Kristall had several materials processing furnaces. They were called Krater 5, Optizon 1, Zona 2, and Zona 3. It also had a biotechnology experiment called the Aniur electrophoresis unit. These experiments were capable of generating 100 kg of raw materials for use on Earth. Located in the docking node was the Priroda 5 camera which was used for Earth resources experiments. Kristall also had several astronomy and astrophysics experiments which were designed to augment experiments that were already located in Kvant-1. Kristall's solar panels were also different from others on Mir. They were designed to be "collapsible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reaction Control System
A reaction control system (RCS) is a spacecraft system that uses thrusters to provide attitude control and translation. Alternatively, reaction wheels are used for attitude control. Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such as with the Harrier "jump jet", may also be referred to as a reaction control system. Reaction control systems are capable of providing small amounts of thrust in any desired direction or combination of directions. An RCS is also capable of providing torque to allow control of rotation (roll, pitch, and yaw). Reaction control systems often use combinations of large and small ( vernier) thrusters, to allow different levels of response. Uses Spacecraft reaction control systems are used for: * attitude control during different stages of a mission; * station keeping in orbit; * close maneuvering during docking procedures; * control o ...

Specific Impulse
Specific impulse (usually abbreviated ) is a measure of how efficiently a reaction mass engine (a rocket using propellant or a jet engine using fuel) creates thrust. For engines whose reaction mass is only the fuel they carry, specific impulse is exactly proportional to the effective exhaust gas velocity. A propulsion system with a higher specific impulse uses the mass of the propellant more efficiently. In the case of a rocket, this means less propellant needed for a given delta-v, so that the vehicle attached to the engine can more efficiently gain altitude and velocity. In an atmospheric context, specific impulse can include the contribution to impulse provided by the mass of external air that is accelerated by the engine in some way, such as by an internal turbofan or heating by fuel combustion participation then thrust expansion or by external propeller. Jet engines breathe external air for both combustion and by-pass, and therefore have a much higher specific impulse than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
04 OK-1
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other hand, t ...

Dissolution Of The Soviet Union
The dissolution of the Soviet Union, also negatively connoted as rus, Разва́л Сове́тского Сою́за, r=Razvál Sovétskogo Soyúza, ''Ruining of the Soviet Union''. was the process of internal disintegration within the Soviet Union (USSR) which resulted in the end of the country's and its federal government's existence as a sovereign state, thereby resulting in its constituent republics gaining full sovereignty on 26 December 1991. It brought an end to General Secretary Mikhail Gorbachev's (later also President) effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide. The Soviet Union had experienced internal stagnation and ethnic separatism. Although highly centralized until its final years, the country was made up of fifteen top-level republics that served as homelands for different ethnicities. By late 1991, amid a catastrophic political crisis, with several republics alre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VTHL
Aircraft can have different ways to take off and land. Conventional airplanes accelerate along the ground until sufficient lift (force), lift is generated for takeoff, and reverse the process to landing, land. Some airplanes can take off at low speed, this being a short takeoff. Some aircraft such as helicopters and Harrier jump jets can VTOL, take off and land vertically. Rockets also usually take off vertically, but some designs can land horizontally. Horizontal takeoff and landing Aircraft Conventional takeoff and landing (CTOL) =Takeoff= Takeoff is the phase of flight in which an aircraft goes through a transition from moving along the ground (taxiing) to flying in the air, usually starting on a runway. For balloon (aircraft), balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Hawker Siddeley Harrier, Harrier), no runway is needed. Takeoff is the opposite of landing. =Landing= Landing is the last part of a flight, where a fly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Return To Launch Site
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pads, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are classified by their orbital payload capacity, ranging from small-lift launch vehicle, small-, medium-lift launch ...

Baikonur Cosmodrome Site 110
Site 110 at the Baikonur Cosmodrome is a launch facility which was used by the N1 rocket during the late 1960s and early 1970s, and by the Energia rocket during the 1980s. Site Site 110 consists of two launch pads: The right (or east) pad, called "110/38" or "110R", was completed first. It was followed by the left (or west) pad, called "110/37" or "110L". The complex was built in the 1960s as part of the Soviet crewed lunar programs, for use by the N1 rocket. A total of five launches were made from the complex: Four N1 launches as well as one Energia launch, carrying the '' Buran'' spaceplane. Following the dissolution of the Soviet Union the Energia and Buran programmes were cancelled, and the complex was abandoned. Usage N1 Site 110 was intended as the launch site for crewed lunar landing missions using the Soyuz 7K-L3 spacecraft and the LK lander. The N1 made four flights, all of which were launched from Site 110, and all of which failed before the first stage had completed ...
