Birmabright
Birmabright is a trade name of the former Birmetals Co. (Birmabright works in Clapgate Lane, Quinton, Birmingham, UK) for various types of lightweight sheet metal in an alloy of aluminium and magnesium. The alloy was introduced by the Birmid Group in 1929 and was particularly noted for its corrosion resistance. Birmal Boats was created in 1930 for the building of light-alloy boats. Birmetals Ltd was formed in 1936 and during the war produced both copper bearing aluminium alloys and the Birmabright magnesium bearing alloys, mainly for aircraft production. The constituents were from 1% to 7% magnesium, with <1% , and the remainder aluminium. The alloys were provided in different temper conditions. e.g. soft, 1/4 hard, 1/2 hard and were designed to be work hardened e.g. by cold pressing into shape. They do not exhibit age har ...

Aluminium Alloys
An aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', Arnold, 1995 Alloys ...

Magnalium
Magnalium is an aluminium alloy with 5% magnesium and 95% aluminum. Properties Alloys with small amounts of magnesium (about 5%) exhibit greater strength, greater corrosion resistance, and lower density than pure aluminium. Such alloys are also more workable and easier to weld than pure aluminium. Alloys with high amounts of magnesium (around 50%) are brittle and more susceptible to corrosion than aluminium. Uses Although they are generally more expensive than aluminium, the high strength, low density, and greater workability of alloys with low amounts of magnesium leads to their use in aircraft and automobile parts. Alloys with about 50% magnesium are brittle and corrode easily, which makes them unsuitable for most engineering uses. However, these alloys are flammable when powdered, are more resistant to corrosion than pure magnesium, and are more reactive than pure aluminium and are therefore used in pyrotechnics as a metal fuel and to produce sparks. Due to the high reactivity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thunderbolt (car)
Thunderbolt was a British Land Speed Record holder of the 1930s, driven by Captain George E.T. Eyston. Records held Between 1937 and 1939, the competition for the Land Speed Record was between two Englishmen: Captain Eyston and John Cobb. Thunderbolt's first record was set at on 19 November 1937 on the Bonneville Salt Flats. Within a year Thunderbolt returned with improved aerodynamics and raised its record to on 27 August 1938. This record only stood for a matter of weeks before John Cobb's Reid-Railton broke the barrier and raised it to on 15 September 1938, as Eyston watched. This inspired him to take Thunderbolt to a new record of . Cobb had held the record for less than 24 hours. Eyston and Thunderbolt held the record for almost a year, until Cobb took it again at a speed of on 23 August 1939. This was the last record attempt before the outbreak of the Second World War. Although Cobb returned after the war and further developed his car to exceed , Thunderb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rover P4
The Rover P4 series is a group of mid-size luxury saloon cars produced by the Rover Company from 1949 until 1964. They were designed by Gordon Bashford. Their P4 designation is factory terminology for this group of cars and was not in day-to-day use by ordinary owners who would have used the appropriate consumer designations for their models such as Rover 90 or Rover 100. Production began in 1949 with the 6-cylinder 2.1-litre Rover 75. Four years later a 2-litre 4-cylinder Rover 60 was brought to the market to fit below the 75 and a 2.6-litre 6-cylinder Rover 90 to top the three-car range. Several variations followed. These cars are very much part of British culture and became known as the 'Auntie' Rovers. They were driven by royalty including Grace Kelly and King Hussein of Jordan whose first ever car was a 1952 75. The P4 series was supplemented in September 1958 by a new conservatively shaped Rover 3-litre P5 but the P4 series stayed in production until 1964 and their re ...

Birmingham
Birmingham ( ) is a city and metropolitan borough in the metropolitan county of West Midlands in England. It is the second-largest city in the United Kingdom with a population of 1.145 million in the city proper, 2.92 million in the West Midlands metropolitan county, and approximately 4.3 million in the wider metropolitan area. It is the largest UK metropolitan area outside of London. Birmingham is known as the second city of the United Kingdom. Located in the West Midlands region of England, approximately from London, Birmingham is considered to be the social, cultural, financial and commercial centre of the Midlands. Distinctively, Birmingham only has small rivers flowing through it, mainly the River Tame and its tributaries River Rea and River Cole – one of the closest main rivers is the Severn, approximately west of the city centre. Historically a market town in Warwickshire in the medieval period, Birmingham grew during the 18th century during the Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Rover
Land Rover is a British brand of predominantly four-wheel drive, off-road capable vehicles, owned by multinational car manufacturer Jaguar Land Rover (JLR), since 2008 a subsidiary of India's Tata Motors. JLR currently builds Land Rovers in Brazil, China, India, Slovakia, and the United Kingdom. The Land Rover name was created in 1948 by the Rover Company for a utilitarian 4WD off-roader; yet today Land Rover vehicles comprise solely upmarket and luxury sport utility cars. Land Rover was granted a Royal Warrant by King George VI in 1951, and 50 years later, in 2001, it received a Queen's Award for Enterprise for outstanding contribution to international trade. Over time, Land Rover grew into its own brand (and for a while also a company), encompassing a consistently growing range of four-wheel drive, off-road capable models. Starting with the much more upmarket 1970 Range Rover, and subsequent introductions of the mid-range Discovery and entry-level Freelander lin ...

Laurent Giles
John Laurent Giles (1901–1969) was an English naval architect who was particularly famous for his sailing yachts. He and his company, Laurent Giles & Partners Ltd, designed more than 1000 boats from cruisers and racing yachts to megayachts. Examples Notable examples of Laurent Giles' work include the famous Vertue (sail numbers suggest that some 230 of these have been made), Wanderer III, the 30' sloop in which Eric and Susan Hiscock circumnavigated, and the race-winning Gulvain, the first ocean racing yacht to be made from an aluminium alloy. His famous ''Myth of Malham'', a revolutionary small displacement yacht for John Illingworth, was inspired by developments in aeronautics; the novel design helped win the Fastnet race in 1947 and 1949. The updated Miranda IV of 1951 had a rudder mounted separately from the aft of the keel (a 'spade rudder') which heralded the arrival of the modern period of yacht design. Laurent Giles described as part of his design philosophy that a ya ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 wo ...

Land Rover Celebrates 65 Years Of Technology & Innovation (8838044808)
Land, also known as dry land, ground, or earth, is the solid terrestrial surface of the planet Earth that is not submerged by the ocean or other bodies of water. It makes up 29% of Earth's surface and includes the continents and various islands. Earth's land surface is almost entirely covered by regolith, a layer of rock, soil, and minerals that forms the outer part of the crust. Land plays important roles in Earth's climate system and is involved in the carbon cycle, nitrogen cycle, and water cycle. One-third of land is covered in trees, 15% is used for crops, and 10% is covered in permanent snow and glaciers. Land terrain varies greatly and consists of mountains, deserts, plains, plateaus, glaciers, and other landforms. In physical geology, the land is divided into two major categories: mountain ranges and relatively flat interiors called cratons. Both are formed over millions of years through plate tectonics. A major part of Earth's water cycle, streams shape the landscape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
