Bristol Centaurus
The Centaurus was the final development of the Bristol Engine Company's series of sleeve valve radial aircraft engines. The Centaurus is an 18-cylinder, two-row design that eventually delivered over . The engine was introduced into service late in the Second World War and was one of the most powerful aircraft piston engines to see service. Design and development Like other Bristol sleeve valve engines, the Centaurus was based on the design knowledge acquired from an earlier design, in this case the Bristol Perseus cylinder. The Centaurus used 18 Perseus cylinders. The same cylinder was in use in the contemporary 14-cylinder Hercules, which was being brought into production when the design of the Centaurus started. The Centaurus had a cylinder swept volume of , nearly as much as the American Wright R-3350 ''Duplex-Cyclone'' large radial, making the Centaurus one of the largest aircraft piston engines to enter production, while that of the Hercules was . The nearly 40 perc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IMI Plc
IMI plc (), formerly Imperial Metal Industries, is a British-based engineering company headquartered in Birmingham, England. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index. History The company was founded by Scottish entrepreneur George Kynoch who opened a percussion cap factory in Witton, West Midlands in 1862, trading as ''Kynoch''. The business soon diversified, manufacturing goods ranging from soap and bicycle components to non-ferrous metals, but by the early 20th century it had developed particular expertise in metallurgy. After World War I it merged with Nobel Industries. In 1926 the company acquired Eley Brothers, an ammunition business. The company, by then known as ''Nobel Explosives'', was one of the four businesses that merged in 1927 to create Imperial Chemical Industries. The Witton site became the head office of ICI Metals. During the Second World War the Witton site was used for the development and production of uranium for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Buckingham
The Bristol Type 163 Buckingham was a British Second World War medium bomber for the Royal Air Force (RAF). Overtaken by events, it was built in small numbers and was used primarily for transport and liaison duties. Design and development In early 1939 Bristol suggested a bomber variant of the Beaufighter with their Hercules engines. British policy at the time was for medium bombers to be obtained from the US allowing British industry to concentrate on heavy bomber designs; nonetheless a design was requested preferably based on an existing aircraft. This meant working with the Beaufighter or Beaufort. Bristol worked on their design first as the Bristol Type 161 then the Type 162 Beaumont.Buttler 2004, p. 88. Air Ministry specification B.7/40 called for a medium bomber to replace the Blenheim. The specification stipulated a speed of at least 300 mph at 5,000 ft, a normal load of 1,000 lb of bombs and a centre turret armed with at least two 0.5 inch (12.7 mm) ...

Blackburn Firecrest
The Blackburn B.48 Firecrest, given the SBAC designation YA.1, was a single-engine naval strike fighter built by Blackburn Aircraft for service with the British Fleet Air Arm during the Second World War. It was a development of the troubled Firebrand, designed to Air Ministry Specification S.28/43, for an improved aircraft more suited to carrier operations. Three prototypes were ordered with the company designation of B-48 and the informal name of "Firecrest", but only two of them actually flew. The development of the aircraft was prolonged by significant design changes and slow deliveries of components, but the determination by the Ministry of Supply in 1946 that the airframe did not meet the requirements for a strike fighter doomed the aircraft. Construction of two of the prototypes was continued to gain flight-test data and the third was allocated to strength testing. The two flying aircraft were sold back to Blackburn in 1950 for disposal and the other aircraft survived u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairey Spearfish
The Fairey Spearfish was a British Carrier-based aircraft, carrier-based, single-engined, torpedo bomber/dive bomber that was ordered from Fairey Aviation for the Fleet Air Arm during World War II. Designed during the war, the prototype did not fly until July 1945. Much larger than earlier naval bombers, it was designed for use aboard the large s that were cancelled after the war and was itself cancelled thereafter. Seven prototypes were ordered, but only five were built, of which four actually flew. They were mostly used for experimental work until the last aircraft was scrapped in 1952. Design and development The Spearfish was designed by Fairey Aviation to British Admiralty, Admiralty List of Air Ministry specifications#1940–1949, Specification O.5/43 as a replacement for the Fairey Barracuda in the torpedo/dive bomber role. In comparison to the Barracuda, the Spearfish had a much more powerful engine, an internal weapons bay and a retractable ASV radar, ASV Mk.XV surface ...

Airliner
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney R-4360 Wasp Major
The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II. First run in 1944, at , it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at the most powerful. It was the last of the Pratt & Whitney Wasp family, and the culmination of its maker's piston engine technology. The war was over before it could power airplanes into combat. It powered many of the last generation of large piston-engined aircraft before turbojets, but was supplanted by equivalent (and superior) powered turboprops (such as the Allison T56). Its main rival was the twin-row, 18-cylinder, nearly displacement, up to Wright R-3350 Duplex-Cyclone, first run some seven years earlier (May 1937). Design and development The R-4360 was a 28-cylinder four-row air-cooled radial engine. Each row of seven air-cooled cylinders possessed a slight angular offset from the previous, forming ...

Bristol Orion
The Bristol Orion aero engine was a two-shaft turboprop intended for use in later marks of the Bristol Britannia and the Canadair CL-44. Although the engine was built and underwent a development program, the BE.25 Orion project was cancelled in 1958 by the British Ministry of Supply in favour of the Rolls-Royce Tyne.Turbojet History And Development 1930-1960 - Volume 1 Great Britain and Germany, Antony L. Kay 2007, The Crowood Press Ltd., , p.149 In addition, interest in turboprop-powered aircraft was beginning to wane, because of the successful introduction of the Boeing 707 and Douglas DC-8 jetliners into airline service. The Orion gas generator had been chosen by French aircraft designer Wibault to power a vectored thrust aircraftPegasus The Heart of the Harrier, Andrew Dow, Pen & Sword Aviation 2009, , p.71/73 which ultimately became the Hawker Siddeley P.1127 but with a Bristol Siddeley Orpheus gas generator which had a compressor derived from the Orion low pressure com ...

Roy Fedden
Sir Alfred Hubert Roy Fedden MBE, FRAeS (6 June 1885 – 21 November 1973) was an engineer who designed most of Bristol Engine Company's successful piston aircraft engine designs. Early life Fedden was born in the Bristol area to fairly wealthy and influential parents. His older brother was the artist Romilly Fedden. Fedden's family was the first in the area to own a car, an interesting parallel with fellow engine designer, Harry Ricardo. This early influence almost certainly led to his future career. Fedden attended Clifton College, but did not do well scholastically and was known primarily for sports. After leaving, he declined to enter the Army, and announced he would apprentice as an engineer. Apprenticeship His apprenticeship was completed in 1906, and he immediately designed a complete car. He managed to convince the local firm of Brazil Straker to hire him, and the design was produced as the successful Shamrock. He remained at Brazil Straker over the following years, and ...

Bristol Proteus
The Bristol Proteus was the Bristol Engine Company's first mass-produced gas turbine engine design, a turboprop that delivered just over 4,000 hp (3,000 kW). The Proteus was a reverse-flow gas turbine. Because the second turbine drove no compressor stages, but only the propeller, this engine was classified as a free-turbine. It powered the Bristol Britannia airliner, small naval patrol craft, hovercraft and electrical generating sets. It was also used to power a land-speed record car, the Bluebird-Proteus CN7. After the merger of Bristol with Armstrong Siddeley the engine became the Bristol Siddeley Proteus, and later the Rolls-Royce Proteus. The Proteus was to have been superseded by the Bristol Orion which would have given a Britannia a 75% increase in power for cruising faster. Design and development The Proteus was to power a very large airliner for use after the war. Design work started in September 1944 with its free turbine and propeller gearbox based on th ...

Blackburn Beverley
The Blackburn B-101 Beverley was a heavy transport aircraft produced by the British aircraft manufacturer Blackburn Aircraft. It was notably the only land-based transport airplane built by Blackburn, a company that otherwise specialised in producing naval fighter aircraft. The Beverley was originally designed by General Aircraft as the ''GAL.60 Universal Freighter'', reflecting its intended use by both military and civil operators. The design process had started during the Second World War, and drew upon the General Aircraft Hamilcar glider. A major design study was conducted in 1945, ahead of Specification C.3/46 being released by the Air Ministry. The company's proposal was accepted and the Air Ministry place an order for one prototype. General Aircraft was absorbed by Blackburn during the late 1940s, who continued the project. On 20 June 1950, the first prototype conducted its maiden flight from the company's Brough facility; it was Britain's second largest landplane at t ...
