Marshall Supercharger
The Marshall supercharger (also known as the Godfrey supercharger) was a Roots-type supercharger based on a patent by John Wilmot Marshall in 1933 Company History The Marshall superchargers were initially manufactured by Marshall Drew and Co Ltd in the 1930s and marketed for increasing car performance. Toward the end of the 1930s Marshall superchargers were listed by Sir George Godfrey and Partners (Holdings) Ltd of Hanworth, Middlesex, made by them to the designs of J.W. Marshall. Godfrey continued to list the Marshall cabin blower until about 1951, after which they listed it as the Godfrey cabin supercharger. In 1969 Sir George Godfrey and Partners (Holdings) Ltd merged with James Howden & Company Ltd under James Howden and Godfrey Ltd. One outcome of this was the merging of compressor interests, as Howden Wade Ltd carried the rights to the Wade supercharger. In 1990 Adams Ricardo Ltd purchased the rights to the Wade and Godfrey compressor ranges from Howden. Applications While ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roots-type Supercharger
The Roots-type blower is a positive displacement lobe pump which operates by pumping a fluid with a pair of meshing lobes resembling a set of stretched gears. Fluid is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust. The most common application of the Roots-type blower has been the induction device on two-stroke diesel engines, such as those produced by Detroit Diesel and Electro-Motive Diesel. Roots-type blowers are also used to supercharge four-stroke Otto cycle engines, with the blower being driven from the engine's crankshaft via a toothed or V-belt, a roller chain or a gear train. The Roots-type blower is named after American inventors and brothers Philander and Francis Marion Roots, founders of the Roots Blower Company of Connersville, Indiana USA, who patented the basic design in 1860 as an air pump for use in blast furnaces and other industrial applications. In 1900, Gottlieb Daimler included a Roots-style blower in a pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Sperrin
The Short SA.4 Sperrin (named after the Sperrin Mountains) was a British jet bomber design of the early 1950s, built by Short Brothers and Harland of Belfast. It first flew in 1951. From the onset, the design had been viewed as a fall-back option in case the more advanced strategic bomber aircraft, then in development to equip the Royal Air Force's nuclear-armed V bomber force, experienced delays; the Sperrin was not put into production because these swept-wing designs, such as the Vickers Valiant, were by then available. As their usefulness as an interim bomber aircraft did not emerge, a pair of flying prototypes were instead used to gather research data on large jet aircraft and to support the development of other technologies, such as several models of jet engines. The two aircraft completed were retired in the late 1950s and ultimately scrapped sometime thereafter. Development The Air Ministry issued a specification on 11 August 1947 B.14/46 for a "medium-range bomber lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superchargers
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

Rotinoff Motors
Rotinoff Motors Ltd was a British commercial vehicle manufacturer based in Colnbrook in western London. The company was founded in 1952 by the Belarusian émigré George Rotinoff. The Rotinoff company specialized in the production of ballast tractors and heavy transport vehicles. The vehicles of Rotinoff were widely used in Europe as tractors for tank transporters. In the Swiss army, the Rotinoff Atlantic GR 7 was used from 1958 - 1991 by the tank troops to haul Centurion tanks. More Rotinoff transporters were in use as road trains in Australia for the transport of cattle. George Rotinoff died in 1959, and the brand name Rotinoff was then discontinued. Worldwide there are still Rotinoff vehicles in operation today and they are coveted collectibles.

Vickers Vanguard
The Vickers Vanguard was a short/medium-range turboprop airliner designed and produced by the British aircraft manufacturer Vickers-Armstrongs. The Vanguard was developed during the mid-to-late 1950s in response to a specification issued by British European Airways (BEA) for a 100 seat airliner; Vickers decided to design such an airliner as a follow-up to the existing Viscount series, the principal difference from which being an expanded airframe that provided considerably more internal volume. Another key innovation was the Tyne engine, which was roughly twice as powerful as the Viscount's Rolls-Royce Dart engine, and allowed for increases in both cruising speed and altitude. Throughout the design process, the needs of two airlines, BEA and Trans-Canada Air Lines (TCA), heavily shaped the Vanguard's specifics. The Vanguard was brought into revenue service on 17 December 1960, around the same time as the commercial availability of a new generation of jet-powered airliners; a ...

Avro Vulcan
The Avro Vulcan (later Hawker Siddeley Vulcan from July 1963) is a jet-powered, tailless, delta-wing, high-altitude, strategic bomber, which was operated by the Royal Air Force (RAF) from 1956 until 1984. Aircraft manufacturer A.V. Roe and Company ( Avro) designed the Vulcan in response to Specification B.35/46. Of the three V bombers produced, the Vulcan was considered the most technically advanced, hence the riskiest option. Several reduced-scale aircraft, designated Avro 707s, were produced to test and refine the delta-wing design principles. The Vulcan B.1 was first delivered to the RAF in 1956; deliveries of the improved Vulcan B.2 started in 1960. The B.2 featured more powerful engines, a larger wing, an improved electrical system, and electronic countermeasures, and many were modified to accept the Blue Steel missile. As a part of the V-force, the Vulcan was the backbone of the United Kingdom's airborne nuclear deterrent during much of the Cold War. Although the ...

Grumman Gulfstream I
The Grumman Gulfstream I (company designation G-159) is a twin-turboprop business aircraft. It first flew on August 14, 1958. Design and development After first rejecting an idea to develop the Grumman Widgeon as an executive transport, the company studied producing an executive transport based on a turbine-powered variant of the naval utility transport Grumman TF-1 Trader. The company had already determined that any new aircraft would have to be turboprop-powered and the Rolls-Royce Dart engine was chosen. Further studies showed that the Trader-based design would not sell and they needed an all-new design with a low-wing and room to stand up in the cabin. In June 1957 the design of G-159 was finalised and Grumman started selling slots on the production line at $10,000 each. The initial customers worked with Grumman on the detailed design and avionics fit. The G-159 was given the name ''Gulfstream'' and on 14 August 1958 the first aircraft, registered ''N701G'', took off from B ...

Fairchild F-27
The Fairchild F-27 and Fairchild Hiller FH-227 were versions of the Fokker F27 Friendship twin-engined turboprop passenger aircraft manufactured under license by Fairchild Hiller in the United States. The Fairchild F-27 was similar to the standard Fokker F27, while the FH-227 was an independently developed stretched version. Design and development The Fokker F27 began life as a 1950 design study known as the P275, a 32-seater powered by two Rolls-Royce Dart turboprops. With the aid of Dutch government funding, the P275 evolved into the F27, which first flew on November 24, 1955. The first prototype was powered by Dart 507s and would have seated 28. To correct a slight tail-heaviness and to allow for more seats, the second prototype (which first flew in January 1957) had a fuselage, which would allow seating for 32. By this stage, Fokker had signed an agreement that would see Fairchild build Friendships in the U.S. as the F-27. The first aircraft of either manufacturer to enter ...

Handley Page Dart Herald
The Handley Page Dart Herald is a 1950s British turboprop passenger aircraft. Design and development In the mid-1950s Handley Page developed a new fast short-range regional airliner, intended to replace the older Douglas DC-3, particularly in third-world countries.''Flight '' 19 August 1955, p. 260. The design, originally known as the HPR.3 Herald, emanated from the drawing office at Handley Page (Reading) Limited—the former Miles Aircraft factory site, which had developed an earlier airliner design, the Miles Marathon. The Herald was an extensive re-development of the original concept of the Marathon, notable for its high mounted wing.Payne 1997, pp. 336–337. Handley Page Reading succeeded in producing a modern design with excellent flight and performance characteristics. However, the company made a serious misjudgement which was, in the end, to cost the company dearly, and like some other classic British aircraft of the time, the Herald missed its chance.

Fokker F27 Friendship
The Fokker F27 Friendship is a turboprop airliner developed and manufactured by the Dutch aircraft manufacturer Fokker. It is the most numerous post-war aircraft manufactured in the Netherlands; the F27 was also one of the most successful European airliners of its era. The F27 was developed during the early 1950s with the intent of producing a capable successor to the earlier piston engine-powered airliners that had become commonplace on the market, such as the Douglas DC-3. A key innovation of the F27 was the adoption of the Rolls-Royce Dart turboprop engine, which produced substantially less vibration and noise which provided improved conditions for passengers; another major comfort feature was cabin pressurisation. Innovative manufacturing techniques were also employed in the aircraft's construction. On 24 November 1955, the F27 made its maiden flight; on 19 November 1958, the type was introduced to revenue service. Shortly after its introduction, the F27 was recognised as be ...

Vickers Viscount
The Vickers Viscount is a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner. The Viscount was well received by the public for its cabin conditions, which included pressurisation, reductions in vibration and noise, and panoramic windows. It became one of the most successful and profitable of the first post-war transport aircraft; 445 Viscounts were built for a range of international customers, including in North America. Development Origins The Viscount was a response to the 1943 Brabazon Committee's proposed Type II design for a post-war small medium-range pressurised aircraft to fly less-travelled routes, carrying 24 passengers up to 1,750 mi (2,816 km) at 200 mph (320 km/h).Cacutt 1989, pp. 323–333.

Wade Supercharger
The Wade supercharger was a Roots-type supercharger designed for internal combustion engines and produced from 1947 by the newly formed Wade Engineering Ltd, of Gatwick Airport, Horley, Surrey. The name 'WADE' comes from Winslett And DEnsham, after Bryan Winslett and Costin Densham. Company History At the end of the war Leslie Mark Ballamy had the idea of repurposing war surplus Marshall cabin air blowers as superchargers for cars. Initially running under his own name, he left the business in 1946 and it was reorganised as North Downs Engineering Co (Nordec). Several members of NORDEC, including the chief designer and the managing director, Marcus Chambers, decided to make their own compressors and to do this created Wade Engineering Ltd at Gatwick airport late in 1947. The early units were sold under the "Ventor" trademark, but soon they became known as Wade superchargers. The company moved premises to Crowhurst Road, Brighton in 1955. In the 1960s the company was taken over by H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
