Clausen Rolling Platform
The Clausen Rolling Platform was a missile launching platform, built at the coastal missile test range of RAE Aberporth, West Wales, in the 1950s. It used a floating platform in a pool of water to simulate the rolling of a ship at sea, without the drawbacks and costs of going to sea. The Platform was first used for development trials of the Seaslug missile. Most of the Aberporth site is on a plateau above 450 foot cliffs. The platform was a 750 ton circular steel caisson floating in a diamond-shaped pool, on a concrete platform just above sea level. The pool was across and deep. Access down the cliffs was made by a cable funicular, taking 11 minutes to descend with a loaded 20 ft long, two-ton missile. The action of the platform was controlled by actuators fixed to the land. They could move the caisson in both 20° roll and 10° pitch axes independently. Variable water ballast within the caisson allowed its dynamic behaviour and period of oscillation to be adjusted.

Clausen Rolling Platform, Aberporth
Clausen is a Danish patronymic surname, literally meaning ''child of Claus'', Claus being a German form of the Greek Νικόλαος, Nikolaos, (cf. Nicholas), used in Denmark at least since the 16th century. The spelling variant Klausen has identical pronunciation (as does the often interchangeable Claussen). The two variants are number 34 and 85 on the top100 of surnames in Denmark. Occurrences of Clausen/Klausen as a surname outside Denmark and Schleswig-Holstein are due to immigration. Immigrants to English-speaking countries sometimes changed the spelling to Clauson. People * Alden W. Clausen, (1923–2013), American businessman and former President of the World Bank * Alf Clausen (born 1941), American film and television musical composer * Andrea Clausen (born 1959), German stage actress (Burgtheater, Vienna) * Arne Clausen (born 1932), Argentine Methodist Pastor * Casey Clausen (born 1981), American football player * Christopher John Clausen (born 1942), American writer ...

Cold War Military Equipment Of The United Kingdom
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Imperial War Museum
Imperial War Museums (IWM) is a British national museum organisation with branches at five locations in England, three of which are in London. Founded as the Imperial War Museum in 1917, the museum was intended to record the civil and military war effort and sacrifice of Britain and British Empire, its Empire during the First World War. The museum's remit has since expanded to include all conflicts in which British or Commonwealth forces have been involved since 1914. As of 2012, the museum aims "to provide for, and to encourage, the study and understanding of the history of modern war and 'wartime experience'." Originally housed in the Crystal Palace at Sydenham Hill, the museum opened to the public in 1920. In 1924, the museum moved to space in the Imperial Institute in South Kensington, and finally in 1936, the museum acquired a permanent home that was previously the Bethlem Royal Hospital in Southwark. The outbreak of the Second World War saw the museum expand both its coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Wolf (missile)
Sea Wolf is a naval surface-to-air missile system designed and built by BAC, later to become British Aerospace (BAe) Dynamics, and now MBDA. It is an automated point-defence weapon system designed as a short-range defence against both sea-skimming and high angle anti-ship missiles and aircraft. The Royal Navy has fielded two versions, the GWS-25 Conventionally Launched Sea Wolf (CLSW) and the GWS-26 Vertically Launched Sea Wolf (VLSW) forms. In Royal Navy service Sea Wolf is being replaced by Sea Ceptor. History The earliest point-defence missile used by the Royal Navy was the Seacat, which had been rapidly developed from an earlier anti-tank missile design, the Malkara. As a weapon originally designed to operate against slow-moving ground vehicles, the missile had subsonic performance and was of limited capability against even early jet aircraft. It was used largely due to the ease which it could be adapted to the role simply by replacing the original wire guidance system with a ...

Automatic Command To Line Of Sight
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 wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam-riding Guidance
Beam-riding, also known as Line-Of-Sight Beam Riding (LOSBR) or beam guidance, is a technique of directing a missile to its target by means of radar or a laser beam. The name refers to the way the missile flies down the guidance beam, which is aimed at the target. It is one of the simplest guidance systems and was widely used on early missile systems, however it had a number of disadvantages and is now found typically only in short-range roles. Basic concept Beam riding is based on a signal that is pointed towards the target. The signal does not have to be powerful, as it is not necessary to use it for tracking as well. The main use of this kind of system is to destroy airplanes or tanks. First, an aiming station (possibly mounted on a vehicle) in the launching area directs a narrow radar or laser beam at the enemy aircraft or tank. Then, the missile is launched and at some point after launch is “gathered” by the radar or laser beam when it flies into it. From this stage onwa ...

Sea Dart
Sea Dart, or GWS.30 was a Royal Navy surface-to-air missile system designed in the 1960s and entering service in 1973. It was fitted to the Type 42 destroyers (United Kingdom and Argentina), Type 82 destroyer and s of the Royal Navy. Originally developed by Hawker Siddeley, the missile was built by British Aerospace after 1977. It was withdrawn from service in 2012. Britain's first naval surface-to-air missile was GWS1 Seaslug, which entered service in 1963. This used beam riding guidance which offered limited accuracy and was useful only against slower targets. The need for a higher performance system was seen even as it entered service. Bristol Aerospace, which had recently introduced the ramjet-powered Bloodhound missile for the RAF, won the ensuing competition with another ramjet design. Compared to Seaslug, Sea Dart was faster, had much greater range, and its semi-active radar homing guidance was much more accurate and allowed attacks against supersonic targets. The s ...
