Nacelle
A nacelle ( ) is a streamlined container for aircraft parts such as Aircraft engine, engines, fuel or equipment. When attached entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a Hardpoint#Pylon, pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman Aviation Works, Farman" type Pusher configuration, "pusher" aircraft, or the World War II-era P-38 Lightning or SAAB J21—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 language, French, in this case from a word for a small boat.

Nacelle (wind Turbine)
A nacelle is a cover Enclosure (electrical), housing that houses all of the generating components in a wind turbine, including the Electric generator, generator, gearbox, drive train, and brake assembly. A notable feature now found on some Wind_farm#Offshore_installations, 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. Wind turbine rotors are stopped, feathered and locked before personnel are dropped down to or picked up from the platforms. Production The European company Nordex produces nacelles in Rostock, Germany and has been producing nacelles at Barásoain, in Navarre, Spain.. As of 2024 it was due to restart production at its nacelle manufacturing plant in West Branch, Iowa. As of February 2025, the company stuck to its plans despite the anti- wind executive orders of the second Trump administration. ...

Podded Engine
A podded engine is a jet engine that has been built up and integrated in its nacelle. This may be done in a podding facility as part of an aircraft assembly process. The nacelle contains the engine, engine mounts and parts which are required to run the engine in the aircraft, known as the EBU (Engine Build Up). The nacelle consists of an inlet, an exhaust nozzle and a cowling which opens for access to the engine accessories and external tubing. The exhaust nozzle may include a thrust reverser. The podded engine is a complete powerplant, or propulsion system, and is usually attached below the wing on large aircraft like commercial airliners or to the rear fuselage on smaller aircraft such as business jets. Engine Build Up The EBU components connect the engine systems with the aircraft systems. Engine build up includes installation of an engine starter, hydraulic pumps, electrical generators and firewire and components which connect the engine to the aircraft. They include the fol ...

Arado Ar 234
The Arado Ar 234 ''Blitz'' (English: lightning) is a jet-powered bomber designed and produced by the German aircraft manufacturer Arado. It was the world's first operational turbojet-powered bomber, seeing service during the final years of the Second World War. Development of the Ar 234 can be traced back to the latter half of 1940 and the request to tender from the Ministry of Aviation to produce a jet-powered high-speed reconnaissance aircraft. Arado was the only respondent with their ''E.370'' design. While its range was beneath that of the Ministry's specification, an initial order for two prototypes was promptly issued to the company, designated ''Ar 234''. While both of the prototypes had been mostly completed prior to the end of 1941, the Junkers Jumo 004 turbojet engines were not available prior to February 1943. Due to engine unreliability, the maiden flight of the Ar 234 V1 was delayed until 30 July 1943. In addition to the original reconnaissance-orientated ''Ar 234 ...

Horizontal-axis Wind Turbine
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. , hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging and remote devices such as traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide range of sizes, with either horizon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pusher Configuration
In aeronautical and naval engineering, pusher configuration is the term used to describe a drivetrain of air- or watercraft with propulsion device(s) after the engine(s). This is in contrast to the more conventional tractor configuration, which places them in front. Though the term is most commonly applied to aircraft, its most ubiquitous propeller example is a common outboard motor for a small boat. “Pusher configuration” describes the specific (propeller or ducted fan) thrust device attached to a craft, either aerostats (airship) or aerodynes (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboats, and propeller-driven snowmobiles. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were "pushers", including the Wright Flyer (1903), the Santos-Dumont 14-bis (1906), the Voisin-Farman I (1 ...

Triumph Thunderbird
The Triumph Thunderbird is a British motorcycle that was introduced by Triumph Engineering, Triumph back 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 Triumph Speed Twin, 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 (motorcycle designer), 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 Thunder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing 777
The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. The 777 is the world's largest twinjet and the most-built wide-body airliner. The jetliner was designed to bridge the gap between Boeing's other wide body airplanes, the twin-engined 767 and quad-engined 747, and to replace aging DC-10 and L-1011 trijets.

Triumph Speed Twin
The Speed Twin 5T is a standard motorcycle that was made by Triumph Engineering, Triumph at their Coventry, and later Meriden factories. Edward Turner (motorcycle designer), 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 several major British marques 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 Straight-twin engine, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Motors Ltd, New Imperial. Turner Special On 16 April 1925 "The Motor Cycle" published drawings by Turner of an Overhead camshaft, 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.
