R-2 Rocket
The R-2 (NATO reporting name SS-2 Sibling) was a Soviet short-range ballistic missile developed from and having twice the range as the R-1 missile (itself a copy of the German V-2). Developed from 1946-1951, the R-2 entered service in numbers in 1953 and was deployed in mobile units throughout the Soviet Union until 1962. A sounding rocket derivative, the R-2A, tested a prototype of the dog-carrying capsule flown on Sputnik 2 in 1957. The same year, the R-2 was licensed for production in The People's Republic of China, where it entered service as the Dongfeng 1. History In 1945 the Soviets captured several key A-4 (V-2) rocket production facilities, and also gained the services of some German scientists and engineers related to the project. Under the supervision of the Special technical Commission (OTK) established by the Soviet Union to oversee rocketry operations in Germany, A-4s were assembled and studied. This prompted the 13 May 1946 decree of the Soviet Council of Mini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korolev City
Korolyov or Korolev ( rus, Королёв, p=kərɐˈlʲɵf) is an industrial city in Moscow Oblast, Russia, well known as the cradle of Soviet and Russian space exploration. As of the 2010 Census, its population was 183,402, the largest as a science city. As of 2018, the population is more than 222,000 people. It was known as Kaliningrad () from 1938 to 1996 and served as the leading Soviet center for production of anti-tank and air-defense guns. In 1946, in the aftermath of World War II, the artillery plant was reconstructed for production of rockets, launch vehicles, and spacecraft, under the guidance of Russian scientist and academician Sergei Korolev, who envisioned, consolidated and guided the activities of many people in the Soviet space-exploration program. The plant later became known as the RKK Energia; when the Vostok space vehicle was being developed, this research center was designated as NII-88 or POB 989. Russian Mission Control Center is also located in Kor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital flight. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight. Unlike cruise missiles, which are restricted to the atmosphere, it is advantageous for ballistic missiles to avoid the denser parts of the atmosphere and they may travel above the atmosphere into outer space. History The earliest form of ballistic missile dates from the 13th century with its use derived from the history of rockets. In the 14th century, the Ming Chinese navy used an early form of a ballistic missile weapon called the Huolongchushui in naval battles against enemy ships.Needham, Volume 5, Part 7, ...

Kapustin Yar
Kapustin Yar (russian: Капустин Яр) is a Russian rocket launch complex in Astrakhan Oblast, about 100 km east of Volgograd. It was established by the Soviet Union on 13 May 1946. In the beginning, Kapustin Yar used technology, material, and scientific support gained from the defeat of Germany in World War II. Numerous launches of test rockets for the Russian military were carried out at the site, as well as satellite and sounding rocket launches. The towns of Znamensk and Kapustin Yar (air base) were built nearby to serve the missile test range. Name The nearby village, Kapustin Yar, was used as the operations base in the early days of the testing site. The actual name can be translated as "cabbage ravine". In public opinion, Kapustin Yar is often referred to as the "Russian Roswell"—the place where the USSR discovered, investigated, or captured alien ships (UFOs). Due to its role as a development site for new technology, Kapustin Yar is also the site of numero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command Guidance
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: * Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. ***Blast: A strong shock wave is provided by the detonation of the explosive. *** Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. *** Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag-shape ...

Oxidizer
An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or " accepts"/"receives" an electron from a (called the , , or ). In other words, an oxidizer is any substance that oxidizes another substance. The oxidation state, which describes the degree of loss of electrons, of the oxidizer decreases while that of the reductant increases; this is expressed by saying that oxidizers "undergo reduction" and "are reduced" while reducers "undergo oxidation" and "are oxidized". Common oxidizing agents are oxygen, hydrogen peroxide and the halogens. In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction. In the second sense, an oxidizing agent is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate. Combust ...

Liquid Oxygen
Liquid oxygen—abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries—is the liquid form of molecular oxygen. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which has continued to the present. Physical properties Liquid oxygen has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of , slightly denser than liquid water, and is cryogenic with a freezing point of and a boiling point of at . Liquid oxygen has an expansion ratio of 1:861 under and , and because of this, it is used in some commercial and military aircraft as a transportable source of breathing oxygen. Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
