International Aero Engines V2500
The IAE V2500 is a two-shaft high-bypass turbofan engine built by International Aero Engines (IAE) which powers the Airbus A320 family, the McDonnell Douglas MD-90, and the Embraer C-390 Millennium. The engine's name is a combination of the Roman numeral V, symbolizing the five original members of the International Aero Engines consortium, which was formed in 1983 to produce the V2500 engine. The 2500 represents the produced by the original engine model, the V2500-A1. FAA type certification for the V2500 was granted in 1988. The maintenance, repair, and operations market for V2500 is close to as of 2015. Development Rolls-Royce based the 10-stage HP compressor on a scale-up of the RC34B eight-stage research unit used in the RB401-06 Demonstrator Engine, but with two additional stages added to the front and rear of the compressor spool. Pratt & Whitney developed the combustor and the 2-stage air-cooled HP turbine, while the Japanese Aero Engine Corporation provided the LP com ...

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

Airbus A320
The Airbus A320 family is a series of Narrow-body aircraft, narrow-body airliners developed and produced by Airbus. The A320 was launched in March 1984, Maiden flight, first flew on 22 February 1987, and was introduced in April 1988 by Air France. The first member of the family was followed by the longer A321 (first delivered in January 1994), the shorter A319 (April 1996), and the even shorter A318 (July 2003). Final assembly takes place in Toulouse in France; Hamburg in Germany; Tianjin in China since 2009; and in Mobile, Alabama in the United States since April 2016. The twinjet has a six-abreast cross-section and is powered by either CFM56 or IAE V2500 turbofans, except the CFM56/PW6000 powered A318. The family pioneered the use of digital fly-by-wire and side-stick flight controls in airliners. Variants offer maximum take-off weights from , to cover a Range (aircraft), range. The 31.4 m (103 ft) long Airbus A318, A318 typically accommodates 107 to 132 passen ... [...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 analog electronic engine control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annular Combustor
A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, the ''combustor'' or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands. The burned mix is exhausted from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the exhaust is directly fed out through the nozzle. A combustor must contain and maintain stable combustion despite very high air flow rates. To do so combustors are carefully designed to first mix and ignite the air and fuel, and then mix in more air to complete the combustion process. Early gas turbine engines used a single chamber known as a can-type combustor. Today three main configurations exist: can, annular, and c ...

Axial Compressor
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IndiGo Airlines
Indigo is a deep color close to the color wheel blue (a primary color in the RGB color space), as well as to some variants of ultramarine, based on the ancient dye of the same name. The word "indigo" comes from the Latin word ''indicum'', meaning "Indian", as the dye was originally exported to Europe from India. It is traditionally regarded as a color in the visible spectrum, as well as one of the seven colors of the rainbow: the color between blue and violet; however, sources differ as to its actual position in the electromagnetic spectrum. The first known recorded use of indigo as a color name in English was in 1289. History ''Indigofera tinctoria'' and related species were cultivated in East Asia, Egypt, India, Bangladesh and Peru in antiquity. The earliest direct evidence for the use of indigo dates to around 4000 BC and comes from Huaca Prieta, in contemporary Peru. Pliny the Elder mentions India as the source of the dye after which it was named. It was imported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McDonnell Douglas MD-90-30
The McDonnell Douglas (later Boeing) MD-90 is an American five-abreast single-aisle airliner developed by McDonnell Douglas from its successful model MD-80. The airliner was produced by the developer company until 1997 and then by Boeing Commercial Airplanes. It was a stretched derivative of the MD-80 and thus the third generation of the DC-9 family. After the more fuel-efficient IAE V2500 high-bypass turbofan was selected, Delta Air Lines became the launch customer on November 14, 1989. The MD-90 first flew on February 22, 1993, and the first delivery was in February 1995 to Delta. The MD-90 competed with the Airbus A320ceo family and the Boeing 737 Next Generation. Its 5 ft (1.4 m) longer fuselage seats 153 passengers in a mixed configuration over up to 2,455 nmi (4,547 km), making it the largest member of the DC-9 family. It kept the MD-88's electronic flight instrument system (EFIS). The shrunken derivative of MD-80 or shorter variant of MD-90, originally ma ...

Embraer KC-390
The Embraer C-390 Millennium is a medium-size, twin-engine, jet-powered military transport aircraft designed and produced by the Brazilian aerospace manufacturer Embraer. It is the heaviest aircraft the company has constructed to date. Work on the project began at Embraer during the mid-2000s, with early efforts centred around a conceptual derivative of the E190 jetliner of a similar size to the Lockheed C-130 Hercules. The company was keen to use pure jet propulsion, instead of turboprops. Support for the venture was forthcoming from both the Brazilian Government and the Brazilian Air Force; in May 2008, the government invested R$800 million (US$440M) in the project's development. On 14 April 2009, Embraer was issued a $1.5 billion contract for two prototypes. At the 2011 Paris Air Show, Embraer announced plans to launch a stretched version of the aircraft as a civilian freighter. Partnerships were promptly formed with various other aerospace companies on the programme, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
