Rolls-Royce R
The Rolls-Royce R is a British aero engine that was designed and built specifically for air racing purposes by Rolls-Royce Limited. Nineteen R engines were assembled in a limited production run between 1929 and 1931. Developed from the Rolls-Royce Buzzard, it was a 37-litre (2,240 cu in) capacity, supercharged V-12 capable of producing just under 2,800 horsepower (2,090 kW), and weighed 1,640 pounds (770 kg). Intensive factory testing revealed mechanical failures which were remedied by redesigning the components, greatly improving reliability. The R was used with great success in the Schneider Trophy seaplane competitions held in England in 1929 and 1931. Shortly after the 1931 competition, an R engine using a special fuel blend powered the winning Supermarine S.6B aircraft to a new airspeed record of over 400 miles per hour (640 km/h). Continuing through the 1930s, both new and used R engines were used to achieve various land and water sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flight Airspeed Record
An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), which also ratifies any claims. Speed records are divided into multiple classes with sub-divisions. There are three classes of aircraft: landplanes, seaplanes, and amphibians; then within these classes, there are records for aircraft in a number of weight categories. There are still further subdivisions for piston-engined, turbojet, turboprop, and rocket-engined aircraft. Within each of these groups, records are defined for speed over a straight course and for closed circuits of various sizes carrying various payloads. Timeline indicates unofficial records, including unconfirmed or unpublicized war secrets. Official records versus unofficial The Lockheed SR-71 Blackbird holds the official Air Speed Record for a manned airbreathing jet engine aircraft with a speed of . The reco ...

Ernest Hives, 1st Baron Hives
Ernest Walter Hives, 1st Baron Hives (21 April 1886 – 24 April 1965), was the one-time head of the Rolls-Royce Aero Engine division and chairman of Rolls-Royce Ltd. Hives was born in Reading, Berkshire to John and Mary Hives, living at 31 Christchurch Road from at least 1891 to 1901. During the Second World War he was closely involved with the design of the Merlin engine as well as numerous later Rolls-Royce jet engines. He began his working life in a local garage. However, in 1903 he got a job working at C.S. Rolls' car company, after fixing Rolls' car. Achievements After becoming a chief test driver in 1908, he led the Rolls-Royce team in the Austrian Alpine Trial in 1913. During the First World War the company designed its first aero-engine, the Eagle, and Hives developed it successfully; by 1916 he was Head of the Experimental Department.

Supermarine
Supermarine was a British aircraft manufacturer that is most famous for producing the Supermarine Spitfire, Spitfire fighter plane during World War II as well as a range of seaplanes and flying boats, and a series of Jet engine, jet-powered fighter aircraft after World War II. The company had successes in the Schneider Trophy for seaplanes, with three wins in a row of 1927, 1929 and 1931. The company was founded in 1913 as Pemberton-Billing Ltd on the River Itchen, Hampshire, River Itchen close to Woolston, Southampton, on ground previously purchased by Noel Pemberton Billing to construct motor launches. It produced a couple of prototypes using quadruplane designs to shoot down zeppelins, the Supermarine P.B.29 and the Supermarine Nighthawk. The aircraft were fitted with the recoilless rifle, recoilless Davis gun and the Nighthawk had a separate powerplant to power a searchlight.The World's Worst Aircraft James Gilbert Upon election as a Member of Parliament (United Kingdom), M ...

Rolls-Royce Kestrel
The Kestrel or type F is a 21 litre (1,300 in³) 700 horsepower (520 kW) class V-12 aircraft engine from Rolls-Royce, their first cast-block engine and the pattern for most of their future piston-engine designs. Used during the interwar period, it provided excellent service on a number of British fighters and bombers of the era, such as the Hawker Fury and Hawker Hart family, and the Handley Page Heyford. The engine also sold to international air forces, and it was even used to power prototypes of German military aircraft types that were later used during the Battle of Britain. Several Kestrel engines remain airworthy today. Design and development Origin The Kestrel came about as a result of the excellent Curtiss D-12, one of the first truly successful cast-block engines. Earlier designs had used individually machined steel cylinders that were screwed onto a crankcase, whereas the cast-block design used a single block of aluminium that was machined to form cylinders.

Napier Lion
The Napier Lion is a 12-cylinder, petrol-fueled 'broad arrow' W12 configuration aircraft engine built by D. Napier & Son from 1917 until the 1930s. A number of advanced features made it the most powerful engine of its day and kept it in production long after other contemporary designs had been superseded. It is particularly well known for its use in a number of racing designs, for aircraft, boats and cars. Design and development Early in the First World War, Napier were contracted to build aero engines to designs from other companies, initially a Royal Aircraft Factory model and then Sunbeams. Both engines proved to be unreliable and in 1916 Napier decided to design an engine with high power, light weight and low frontal area. Napier's engineers laid out the engine with its 12 cylinders in what they called a "broad arrow"—three banks of four cylinders sharing a common crankcase. This suggested the design's first name, the Triple-Four. The configuration is also known as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Griffon
The Rolls-Royce Griffon is a British 37-litre (2,240 cu in) capacity, 60-degree V-12, liquid-cooled aero engine designed and built by Rolls-Royce Limited. In keeping with company convention, the Griffon was named after a bird of prey, in this case the griffon vulture. Design work on the Griffon started in 1938 at the request of the Fleet Air Arm, for use in new aircraft designs such as the Fairey Firefly. In 1939 it was also decided that the engine could be adapted for use in the Spitfire. Development was stopped temporarily to concentrate efforts on the smaller Merlin and the 24-cylinder Vulture; the engine did not go into production until the early 1940s. The Griffon was the last in the line of V-12 aero engines to be produced by Rolls-Royce with production ceasing in 1955. Griffon engines remain in Royal Air Force service today with the Battle of Britain Memorial Flight and power the last remaining airworthy Avro Shackleton. Design and development Origins Accor ...

Supermarine Spitfire
The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries before, during, and after World War II. Many variants of the Spitfire were built, from the Mk 1 to the Rolls-Royce Griffon engined Mk 24 using several wing configurations and guns. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts; around 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary figh ...

Rolls-Royce Merlin
The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litres (1,650 cu in) capacity. Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called ''Merlin'' following the company convention of naming its four-stroke piston aero engines after birds of prey. After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane and Supermarine Spitfire. The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined Avro Lancaster heavy bomber. A series of rapidly-applied developments, brought about by wartime needs, markedly improved the engine's performance and durability. Starting at 1,000 hp for the first production models, most late war versions produced just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donald Campbell
Donald is a masculine given name derived from the Gaelic name ''Dòmhnall''.. This comes from the Proto-Celtic *''Dumno-ualos'' ("world-ruler" or "world-wielder"). The final -''d'' in ''Donald'' is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers, and partly associated with the spelling of similar-sounding Germanic names, such as ''Ronald''. A short form of ''Donald'' is ''Don''. Pet forms of ''Donald'' include ''Donnie'' and ''Donny''. The feminine given name ''Donella'' is derived from ''Donald''. ''Donald'' has cognates in other Celtic languages: Modern Irish ''Dónal'' (anglicised as ''Donal'' and ''Donall'');. Scottish Gaelic ''Dòmhnall'', ''Domhnull'' and ''Dòmhnull''; Welsh '' Dyfnwal'' and Cumbric ''Dumnagual''. Although the feminine given name ''Donna'' is sometimes used as a feminine form of ''Donald'', the names are not etymologically related.

Malcolm Campbell
Major Sir Malcolm Campbell (11 March 1885 – 31 December 1948) was a British racing motorist and motoring journalist. He gained the world speed record on land and on water at various times, using vehicles called ''Blue Bird'', including a 1921 Grand Prix Sunbeam. His son, Donald Campbell, carried on the family tradition by holding both land speed and water speed records. Early life and family Campbell was born on 11 March 1885 in Chislehurst, Kent, the only son of William Campbell, a Hatton Garden diamond seller. He attended the independent Uppingham School. In Germany, learning the diamond trade, he gained an interest in motorbikes and races. Returning to Britain, he worked for two years at Lloyd's of London for no pay, then for another year at £1 a week. Between 1906 and 1908, he won all three London to Land's End Trials motorcycle races. In 1910, he began racing cars at Brooklands.
