De Havilland Gnome
The Rolls-Royce Gnome is a British turboshaft engine originally developed by the de Havilland Engine Company as a licence-built General Electric T58, an American mid-1950s design. The Gnome came to Rolls-Royce after their takeover of Bristol Siddeley in 1966, Bristol having absorbed de Havilland Engines Limited in 1961. A licence to manufacture the T58 was purchased in 1958. The T58 had begun bench testing in 1955 and by 1958 had already been used in helicopters and de Havilland were able to test their first engines in a Westland Whirlwind and Wasp helicopters in August 1959 and March 1960 respectively. A free-turbine turboshaft, it was used in helicopters such as the Westland Sea King and Westland Whirlwind. The design was sub-licensed to Alfa-Romeo. There were two series produced: the "H" turboshaft for helicopter use, and the "P" turboprop for fixed-wing aircraft.

Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.

City Of Norwich Aviation Museum
The City of Norwich Aviation Museum is a volunteer-run museum and charitable trust dedicated to the preservation of the aviation history of the county of Norfolk, England. The museum is located on the northern edge of Norwich International Airport and is reached by road through the village of Horsham St Faith. History In 2016, a number of aircraft had to be moved to make room for the Norwich Northern Distributor Road, Northern Distributor Road. Although part of the museum property was given up for the road, the footprint of the museum grew slightly due to a land swap. The museum welcomed EI-RJN, a 21-year old Avro RJ85, formerly operated by CityJet, as an exhibit in October 2020. The jet had to be lifted over the Northern Distributor Road by crane. The museum acquired the collections of the Fenland and West Norfolk Aviation Museum in 2022 when the latter closed. At the same time, it began building a new expansion called Fenland Hall to house the collection. Collection Ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boeing Vertol CH-46 Sea Knight
The Boeing Vertol CH-46 Sea Knight is an American medium-lift tandem rotors, tandem-rotor transport helicopter powered by twin turboshaft aircraft engine, engines. It was designed by Piasecki Helicopter, Vertol and manufactured by Boeing Helicopters, Boeing Vertol following Vertol's acquisition by Boeing. Development of the Sea Knight, which was originally designated by the firm as the Vertol Model 107, commenced during 1956. It was envisioned as a successor to the first generation of rotorcraft, such as the Piasecki H-21, H-21 "Flying Banana", that had been powered by Reciprocating engine, piston engines; in its place, the V-107 made use of the emergent turboshaft engine. On 22 April 1958, the V-107 prototype performed its maiden flight. During June 1958, the US Army awarded a contract for the construction of ten production-standard aircraft, designated as the YHC-1A, based on the V-107; this initial order was later cut down to three YHC-1As. During 1961, the United States Mari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell 204/205
The Bell 204 and 205 are the civilian versions of the UH-1 Iroquois single-engine military helicopter of the Huey family of helicopters. They are type-certificated in the transport category and are used in a wide variety of applications, including crop dusting, cargo lifting, Forestry Operations, and aerial firefighting. Development Bell designed its Model 204 in response to a 1955 United States Army requirement for a utility helicopter. The 204 was a giant step forward in helicopter design, being one of the first to be powered by a turboshaft. The turboshaft engine radically improved the practicality of the helicopter due to its light weight and high power-to-weight ratio, lower fuel consumption, and lower maintenance and operating costs. The use of a turboshaft in the 204 allowed it to carry a useful payload over respectable ranges and at reasonable speeds, which resulted in the 204 and subsequent 205 becoming the most successful western helicopter series in terms of nu ...

Agusta A
Agusta was an Italian helicopter manufacturer. It was based in Samarate, Northern Italy. The company was founded by Count Giovanni Agusta in 1923, who flew his first aeroplane in 1907. The MV Agusta motorcycle manufacturer began as an offshoot of the Agusta aviation company at the end of the Second World War, as a means to save the jobs of employees of the Agusta firm. In July 2000, Agusta merged with Westland Helicopters to form AgustaWestland S.p.A., a multinational helicopter design and manufacturing company, and a wholly owned subsidiary of Leonardo S.p.A. History From 1952, the company became involved in helicopter manufacturing, first building Bell helicopters under licence, but later Sikorsky, Boeing and McDonnell Douglas products as well. The company also had ambitions to design and build its own helicopters. The Agusta A.101 and the Agusta A.106 can be considered the best of its earlier attempts. Others included the AB.102, A.103, A.104, and A.115. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FADEC
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or " engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines. History The goal of any engine control system is to allow the engine to perform at maximum efficiency for a given condition. Originally, engine control systems consisted of simple mechanical linkages connected physically to the engine. By moving these levers the pilot or the flight engineer could control fuel flow, power output, and many other engine parameters. The mechanical/hydraulic engine control unit for Germany's BMW 801 piston aviation radial engine of World War II was just one notable example of this in its later stages of development. This mechanical engine control was progressively replaced first by analogue electronic engine cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Propellers
de Havilland Propellers was established in 1935, as a division of the de Havilland Aircraft company when that company acquired a licence from the Hamilton Standard company of America for the manufacture of variable-pitch propellers at a cost of about £20,000. Licence negotiations were completed in June 1934. At the same time an extensive new factory, claimed to be one of the largest in the world, was laid down at Lostock, Bolton, some distance away from de Havilland's main aircraft plant at Hatfield. This factory was built in only nine months as part of the government's emergency pre-war shadow-factory programme. de Havilland Propellers, Ltd., was incorporated on 27 April 1946, with the main headquarters at Hatfield as the centre of design, development, and flight-testing, but with the main production plant still at Lostock in Lancashire. Work on missiles began in the late 1940s, early 1950s at the Hatfield plant in facilities which had been used during the war for the de ...
