Bluebird K7
''Bluebird K7'' is a jet engined hydroplane which Britain's Donald Campbell set seven world water speed records between 1955 and 1967. ''K7'' was the first successful jet-powered hydroplane, and was considered revolutionary when launched in January 1955. Campbell and ''K7'' were responsible for adding almost to the water speed record, taking it from existing mark of to just over . Donald Campbell was killed in an accident with a much modified ''K7'', on 4 January 1967, whilst making a bid for his eighth water speed record, with his aim to raise the record to over on Coniston Water. Design Donald Campbell began his record-breaking career in 1949 following the death of his father, Sir Malcolm Campbell. Initially, he had been using his father's 1939-built Rolls-Royce 'R' type powered propeller-driven hydroplane '' Blue Bird K4'' for his attempts, but he met with little success and suffered a number of frustrating setbacks. In 1951, ''K4'', which had been modified to a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Pitch Axis (kinematics)
An aircraft in flight is free to rotate in three dimensions: '' yaw'', nose left or right about an axis running up and down; ''pitch'', nose up or down about an axis running from wing to wing; and ''roll'', rotation about an axis running from nose to tail. The axes are alternatively designated as ''vertical'', ''lateral'' (or ''transverse''), and ''longitudinal'' respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft. These definitions were analogously applied to spacecraft when the first manned spacecraft were designed in the late 1950s. These rotations are produced by torques (or moments) about the principal axes. On an aircraft, these are intentionally produced by means of moving control surfaces, which vary the distribution of the net aerodynamic force about the vehicle's center of gravity. Elevators (moving flaps on the horizontal tail) produce pitch, a rudder on the vertical tail produces yaw, and ailerons (flaps on the wing ...

Land Speed Record
The land speed record (or absolute land speed record) is the highest speed achieved by a person using a vehicle on land. There is no single body for validation and regulation; in practice the Category C ("Special Vehicles") flying start regulations are used, officiated by regional or national organizations under the auspices of the Fédération Internationale de l'Automobile (FIA). The land speed record (LSR) is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes"). Two runs are required in opposite directions within one hour, and a new record mark must exceed the previous one by at least one percent to be validated. History The first regulator was the ''Automobile Club de France'', which proclaimed itself arbiter of the record in about 1902. Until 1903, trains held the land speed record for fastest vehicles in which people could travel. Different clubs had different standards and did not always recognize the same wor ...

Mobil
Mobil is a petroleum brand owned and operated by American oil and gas corporation ExxonMobil. The brand was formerly owned and operated by an oil and gas corporation of the same name, which itself merged with Exxon to form ExxonMobil in 1999. A direct descendant of Standard Oil, Mobil was originally known as the Standard Oil Company of New York (shortened to Socony) after Standard Oil was Standard Oil Co. of New Jersey v. United States, split into 34 different entities in a 1911 Supreme Court decision. Socony merged with Vacuum Oil Company, from which the Mobil name first originated, in 1931 and subsequently renamed itself to Socony-Vacuum Oil Company. Over time, Mobil became the company's primary identity, which incited another renaming in 1963, this time to Mobil Corporation. Mobil credits itself with being the first company to introduce Pay at the pump, paying at the pump at its gas stations, the first company to produce jet aviation fuel, as well as the first company to intr ...

Lake Mead
Lake Mead is a reservoir formed by the Hoover Dam on the Colorado River in the Southwestern United States. It is located in the states of Nevada and Arizona, east of Las Vegas. It is the largest reservoir in the US in terms of water capacity. Lake Mead provides water to the states of Arizona, California, and Nevada as well as some of Mexico, providing sustenance to nearly 20 million people and large areas of farmland. At maximum capacity, Lake Mead is long, at its greatest depth, has a surface elevation of above sea level, has a surface area of , and contains 28.23 million acre-feet (32.236 km³) of water. The lake has remained below full capacity since 1983 owing to drought and increased water demand.

Ullswater
Ullswater is the second largest lake in the English Lake District, being about long and wide, with a maximum depth a little over . It was scooped out by a glacier in the Last Ice Age. Geography It is a typical Lake District "ribbon lake", formed after the last ice age by a glacier scooping out the valley floor, which then filled with meltwater. Ullswater was formed by three glaciers. Surrounding hills give it the shape of an extenuated "Z" with three segments or reaches winding through them. For much of its length, Ullswater formed the border between the historic counties of Cumberland and Westmorland. Etymology The origin of the name Ullswater is uncertain. Whaley suggests "Ulf's lake", from Old Norse personal name Ulfr plus Middle English water, influenced in usage by the Old Norse ''vatn'' (water or lake). ''Ulfr'' is also the Old Norse noun meaning wolf, and Hutchinson thought that the name might refer to the lake as a resort of wolves, or to its elbow-shaped bend (citi ...

Infinity
Infinity is that which is boundless, endless, or larger than any natural number. It is often denoted by the infinity symbol . Since the time of the ancient Greeks, the philosophical nature of infinity was the subject of many discussions among philosophers. In the 17th century, with the introduction of the infinity symbol and the infinitesimal calculus, mathematicians began to work with infinite series and what some mathematicians (including l'Hôpital and Bernoulli) regarded as infinitely small quantities, but infinity continued to be associated with endless processes. As mathematicians struggled with the foundation of calculus, it remained unclear whether infinity could be considered as a number or magnitude and, if so, how this could be done. At the end of the 19th century, Georg Cantor enlarged the mathematical study of infinity by studying infinite sets and infinite numbers, showing that they can be of various sizes. For example, if a line is viewed as the set of all o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sponson
Sponsons are projections extending from the sides of land vehicles, aircraft or watercraft to provide protection, stability, storage locations, mounting points for weapons or other devices, or equipment housing. Watercraft On watercraft, a sponson is a projection that extends outward (usually from the hull, but sometimes other parts of the vessel) to improve stability while floating, or to act as a securing point for other equipment. Vessels with unstable body shapes or unevenly distributed weight are likely to feature sponsons to help prevent capsizing or other instabilities. On many vessels, these projections from the main body of the vessel can be attached and removed quickly and fairly easily. Canoes and kayaks sometimes feature sponson attachments as well, for stability in rough waters. These differ from outriggers, which extend a significant distance away from the body of the craft, and are employed on craft designed for open waters. A sponson's terminus is close to the cr ...
