Rocket Sled
A rocket sled is a test platform that slides along a track (e.g. set of rails), propelled by rockets. A rocket sled differs from a rocket car in not using wheels; at high speeds wheels would spin to pieces due to the extreme centrifugal forces. Apart from rare examples running on snow or ice (such as Max Valier's RAK BOBs of the late 1920s and Harry Bull's BR-1 in 1931), most rocket sleds run on a track. Although some rocket sleds ride on single beams or rails, most use a pair of rails. Standard gauge (1.435 m / 56.5 in) is common but sled tracks of narrower or wider gauge also exist. The rail cross-section profile is usually that of a Vignoles rail, commonly used for railroads. Sliding pads, called "slippers", are curved around the head of the rails to prevent the sled from flying off the track. Air cushions and magnetic levitation have also been used as alternatives, with potential benefits including reduced sled vibration. A rocket sled holds the land-based speed ...

Rocket Sled Track
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to Acceleration, accelerate without using any surrounding Atmosphere of Earth, air. A rocket engine produces thrust by Reaction (physics), reaction to exhaust expelled at high speed. Rocket engines work entirely from rocket propellant, propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with Airbreathing jet engine, airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, Reaction control system, auxiliary reaction engines, gimballed thrust, Reaction wheel, momentum wheels, Thrust vectoring, deflection of ...

Murphy's Law
Murphy's law is an adage or epigram that is typically stated as: "Anything that can go wrong will go wrong." Though similar statements and concepts have been made over the course of history, the law itself was coined by, and named after, American aerospace engineer Edward A. Murphy Jr.; its exact origins are debated, but it is generally agreed it originated from Murphy and his team following a mishap during rocket sled tests some time between 1948 and 1949, and was finalized and first popularized by testing project head John Stapp during a later press conference. Murphy's original quote was the precautionary design advice that "If there are two or more ways to do something and one of those results in a catastrophe, then someone will do it that way." The law entered wider public knowledge in the late 1970s with the publication of Arthur Bloch's 1977 book ''Murphy's Law, and Other Reasons Why Things Go WRONG'', which included other variations and Corollary, corollaries of the law. ...

QinetiQ
QinetiQ ( as in '' kinetic'') is a British defence technology company headquartered in Farnborough, Hampshire. It operates primarily in the defence, security and critical national infrastructure markets and run testing and evaluation capabilities for air, land, sea and target systems. As a private entity, QinetiQ was created in April 2001; prior to this its assets had been part of Defence Evaluation and Research Agency (DERA), a now-defunct British government organisation. While a large portion of DERA's assets, sites, and employees were transferred to QinetiQ, other elements were incorporated into Defence Science and Technology Laboratory (DSTL), which remains in government ownership. Some former DERA locations have thus become key sites for QinetiQ. These include Farnborough, Hampshire; MoD Boscombe Down, Wiltshire; and Malvern, Worcestershire. In February 2006, QinetiQ was floated on the London Stock Exchange. The privatisation process was subject to an inquiry by the U ...

RAF Langford Lodge
Langford Lodge Airfield is a former United States Army Air Forces and Royal Air Force station near Belfast, Northern Ireland. Today the airfield is owned by RLC (UK) a subsidiary of RLC Engineering Group which is headquartered in the Isle of Man. Langford Lodge is located on the eastern shores of Lough Neagh and close to RAF Aldergrove/Belfast International Airport and the former RAF Nutts Corner. The site was also known as No. 20 Satellite Landing Ground. History Planned to be a Satellite Landing Ground for No. 23 Maintenance Unit at RAF Aldergrove, Langford Lodge was selected in October 1941 to be developed as an air deport for the maintenance and repair of USAAF aircraft. A scheme was devised whereby the British Ministry of Aircraft Production would build the airfield and necessary facilities, while the American Lockheed Aircraft Corporation would staff the depot with civilian employees. Built during January-October 1942, and extended during the winter of 1943-44, the airfi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Hurricane Mesa
Hurricane Mesa () is a Utah landform near Hurricane, Utah, used for Cold War tests of rocket ejection seats for supersonic aircraft at the Hurricane Supersonic Research Site. The mesa is "flat bedrock of faultless Shinarump conglomerate" above the Virgin River valley, which allowed clearance for assessment of a longer flight trajectory up from the mesa and over the cliff for the test object (e.g., the anthropoid simulator—dummy—named "Hurricane Sam"). Currently the facility is still used to test military ejection seats for the US and Foreign Govt's. References {{Authority control Landforms of Washington County, Utah Mesas of Utah ...
