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 1968, 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. Design and development A two-stage turbine drives the 10 stage all-axial compressor, whilst a single-stage fr ...

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 by a turbine 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. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to ...

Caernarfon Airworld Aviation Museum
Caernarfon Airworld Aviation Museum is an air museum located on the former Royal Air Force station at Llandwrog, near Caernarfon in North Wales. History The airfield was known as RAF Llandwrog, opening in January 1941 as a RAF Bomber Command airfield for training gunners, radio operators and navigators and closed after the end of the Second World War in 1945. Due to the large numbers of aircraft crashing in the nearby mountains of Snowdonia, it was here that the RAF Mountain Rescue Service was formed in 1943. Postwar, the airfield was used as a storage facility for chemical weapons recovered from Europe. It reopened in 1969 and remains in civil operation today as Caernarfon Airport. The museum opened in 1988, and is located in a purpose built hangar. Aircraft on display The museum has the following aircraft on display: * Westland Whirlwind helicopter * Gloster Javelin (nose section) * Hawker Sea Hawk * de Havilland Vampire T11 * Hawker Hunter F1 * BAe Harrier T2 * Slingsb ...

The Helicopter Museum (Weston)
The Helicopter Museum in Weston-super-Mare, North Somerset, England, is a museum featuring a collection of more than 80 helicopters and autogyros from around the world, both civilian and military. It is based at the southeastern corner of the former Weston-super-Mare Airport. History The museum originated in 1958 when its founder, aviation writer and historian Elfan ap Rees, began to build up a private collection of rotorcraft documentation and artefacts. Over the next ten years his collection grew and in 1969 he acquired his first complete helicopter, a Bristol Sycamore Mk.3. In 1974, ap Rees purchased a Bristol Belvedere and formed a volunteer group to restore it. In December 1976, an ex Royal Navy Westland Whirlwind HAS Mk.7 was acquired and added to the collection. In 1977 and 1978, more aircraft were added, including an ex Royal Air Force Bristol Sycamore HC Mk.14 and several rare prototypes: the Fairey Ultra-Light tip-jet driven helicopter, the Thruxton Gadfly HDW.1 tw ...

De Havilland Aircraft Heritage Centre
The de Havilland Aircraft Museum, formerly the de Havilland Aircraft Heritage Centre, is a volunteer-run aviation museum in London Colney, Hertfordshire, England. The collection is built around the definitive prototype and restoration shops for the de Havilland Mosquito and also includes several examples of the de Havilland Vampire – the third operational jet aircraft in the world. The museum is the largest such museum devoted to one manufacturer in the country. History Salisbury Hall The site has been occupied by a number of large manor houses since the 9th Century. The present house was built around 1668 by the London banker James Hoare, bringing with it associations with Charles II and Nell Gwynne, who lived in a cottage by the bridge to the Hall. The Hall subsequently passed through various hands, and during the latter part of the 19th century was occupied by a succession of farmers. However, about 1905 Lady Randolph Churchill, as Mrs. Cornwallis West, came here to l ...

Boeing Vertol CH-46 Sea Knight
The Boeing Vertol CH-46 Sea Knight is a medium-lift tandem-rotor transport helicopter powered by twin turboshaft engines. It was designed by Vertol and manufactured by 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 H-21 "Flying Banana", that had been powered by 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 though. During 1961, the US Marine Corps (USMC), which had been studying its requirements for a medium-lift, twin-turbine cargo/troop assault helicopter, ...

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 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 numbers built.Frawley, ...

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 airplane 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 Finmeccanica. 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 also pro ...

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 analog electronic engine control ...

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. 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, and with the main production plant at Lostock in Lancashire. The factory had been built in only nine months as part of the government's emergency pre-war shadow-factory programme. 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 development and testing of aircraft propellers. By the early sixties, the company became Hawker Siddeley Dynamics which in turn became ''British Aerospace Dynamics,'' later BAE Systems (Guided Weapons ...
