Nacelle Du Patrie 1906 (2)
A nacelle ( ) is a "streamlined body, sized according to what it contains", such as an engine, fuel, or equipment on an aircraft. When attached by a pylon entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft cockpit may also be housed in a nacelle, rather than in a conventional fuselage. Etymology Like many aviation terms, the word comes from French, in this case from a word for a small boat. Development The development of the Arado Ar 234, merging the four nacelles into two The Arado Ar 234 was one of the first operational jet aircraft with engines mounted in nacelles. During its development, the four jet engines were merged from having four distinct nacelles, all of which contained their own landing gear wheel, to two nacelles with two engin ...

Eurofighter Typhoon
The Eurofighter Typhoon is a European multinational twin-engine, canard delta wing, multirole fighter. The Typhoon was designed originally as an air-superiority fighter and is manufactured by a consortium of Airbus, BAE Systems and Leonardo that conducts the majority of the project through a joint holding company, Eurofighter Jagdflugzeug GmbH. The NATO Eurofighter and Tornado Management Agency, representing the UK, Germany, Italy and Spain, manages the project and is the prime customer. The aircraft's development effectively began in 1983 with the Future European Fighter Aircraft programme, a multinational collaboration among the UK, Germany, France, Italy and Spain. Previously, Germany, Italy and the UK had jointly developed and deployed the Panavia Tornado combat aircraft and desired to collaborate on a new project, with additional participating EU nations. However disagreements over design authority and operational requirements led France to leave the consortium to deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nacelle (wind Turbine)
A nacelle is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train A drivetrain (also frequently spelled as drive train or sometimes drive-train) is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components o ..., and brake assembly. A notable feature now found on some off-shore wind turbines is a large sturdy helicopter-hoisting platform built on top of the nacelle, capable of supporting service personnel and their tools, winched down to the platform from a helicopter hovering above it.Eize de VriesClose up: Alstom Haliade 6MW Prototype ''Windpower Monthly'', 11 July 2012.

Royal Enfield Bullet
The Royal Enfield Bullet was originally an overhead-valve single-cylinder four-stroke motorcycle made by Royal Enfield in Redditch, Worcestershire, now produced by Royal Enfield (India) at Chennai, Tamil Nadu, a company originally founded by Madras Motors to build Royal Enfield motorcycles under licence in India. The Royal Enfield Bullet has the longest unchanged production run of any motorcycle having remained continuously in production since 1948. The Bullet marque is even older, and has passed 75 years of continuous production. The Royal Enfield and Bullet names derive from the British company which had been a subcontractor to Royal Small Arms Factory in Enfield, London. Evolution The Bullet has evolved from a four-stroke engine with exposed valve-gear to the latest all-alloy unit construction engine with electronic fuel-injection. 1931–1939 Introduced in 1931 as a four-stroke single-cylinder motorcycle, this model was the first to feature the Bullet name.

Triumph Tiger 100
The Tiger 100 (T100) was a standard motorcycle first made by the British motorcycle company Triumph in 1939. Production ceased when the Triumph factory was destroyed by German bombing in 1940 during World War 2, but recommenced in 1946. Several variants were manufactured until 1973. Development Pre-war production With the sales success of the Triumph Speed Twin, Edward Turner, Triumph's motorcycle designer, looked further into developing the potential of the new parallel twin motor. The lighter and more powerful Tiger 100 was developed as a sports enthusiasts' machine, and as with previous models the "100" referred to its claimed maximum speed in miles per hour (mph). Technical changes over the Speed Twin included forged alloy pistons, a very early use of the technology. The cylinders were forged in a single casting and held in place by eight studs, instead of the Speed Twin's six. The Tiger 100 featured a single Amal carburetor, possible thanks to the 360-degree firing inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triumph Thunderbird
The Triumph Thunderbird is a British motorcycle that was introduced by Triumph in 1949 and produced in many forms until 1966. The name was used three more times for new and distinct Triumph models. Original Triumph: 6T Thunderbird To capture the American market, the 6T Thunderbird used a variant of the earlier Speed Twin's parallel twin engine, bored out from 500 cc to 650 cc to give the added horsepower American customers demanded. The concept of enlarging the Speed Twin, the Thunderbird name and its 'paper dart' logo were thought up by managing director Edward Turner on one of his regular trips to Triumph's operations in the USA. The 'paper dart' logo was embossed onto the chain case cover on Thunderbirds from 1955 to 1962 and can be seen upon closer examination on the supplied photograph of the 1962 model. Previously, it appeared as a decal on the headlamp nacelle. The 6T Thunderbird was launched publicly at Montlhéry near Paris, where three standard-product ...

Triumph Speed Twin
The Speed Twin 5T is a standard motorcycle that was made by Triumph at their Coventry, and later Meriden factories. Edward Turner, Triumph’s Chief Designer and Managing Director, launched the Triumph Speed Twin at the 1937 National Motorcycle Show. It was a 500 cc OHV vertical twin in a lightweight frame and the first truly successful British parallel twin, setting the standard for many twins to follow. After World War II the Speed Twin was responsible for the survival of Triumph - and every major British marque offered a 500 cc twin designed on similar lines to the Speed Twin. History Edward Turner’s Triumph twin was a major turning point for the British motorcycle industry, as although a 500 cc parallel twin of medium capacity was not revolutionary, the 5T Speed Twin model was lighter than many contemporary singles with significantly more power and torque. Early models were only available in 'Amaranth red' with hand painted gold pinstripes to set off the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Turner (motorcycle Designer)
Edward Turner (24 January 1901 – 15 August 1973) was an English motorcycle designer. He was born in Camberwell in the London Borough of Southwark, on the day King Edward VII was proclaimed King. In 1915, Turner had his first ride on a motorcycle, a Light Tourist New Imperial. Turner Special On 16 April 1925 "The Motor Cycle" published drawings by Turner of an OHC single he had designed, using a series of vertically stacked gears to drive the overhead camshaft. A subsequent redesign used bevel gears to drive a vertical camshaft, operating the valves through rockers. The only shared aspects of the two designs were the bore and stroke, , with the barrel being sunk into the crankcases. The head could be removed from either design complete with undisturbed valve gear. Turner built his first bike in 1927, using his second design, a 350 cc OHC single. ''The Motor Cycle'' published a photograph of Turner's patented engine, mounted in his motorcycle called the Turner Specia ...

Boeing E-3 Sentry
The Boeing E-3 Sentry is an American airborne early warning and control (AEW&C) aircraft developed by Boeing. E-3s are commonly known as AWACS (Airborne Warning and Control System). Derived from the Boeing 707 airliner, it provides all-weather surveillance, command, control, and communications, and is used by the United States Air Force, NATO, French Air and Space Force, Royal Saudi Air Force and Chilean Air Force. The E-3 is distinguished by the distinctive rotating radar dome (rotodome) above the fuselage. Production ended in 1992 after 68 aircraft had been built. In the mid-1960s, the U.S. Air Force (USAF) was seeking an aircraft to replace its piston-engined Lockheed EC-121 Warning Star, which had been in service for over a decade. After issuing preliminary development contracts to three companies, the USAF picked Boeing to construct two airframes to test Westinghouse Electric and Hughes's competing radars. Both radars used pulse-Doppler technology, with Westinghouse's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
