Cfm56-5
The CFM International CFM56 (U.S. military designation F108) series is a Franco-American family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of . CFMI is a 50–50 joint-owned company of Safran Aircraft Engines (formerly known as Snecma) of France, and GE Aviation (GE) of the United States. Both companies are responsible for producing components and each has its own final assembly line. GE produces the high-pressure compressor, combustor, and high-pressure turbine, Safran manufactures the fan, gearbox, exhaust and the low-pressure turbine, and some components are made by Avio of Italy and Honeywell from the US. The engines are assembled by GE in Evendale, Ohio, and by Safran in Villaroche, France. The completed engines are marketed by CFMI. Despite initial export restrictions, it is the most used turbofan aircraft engine in the world, in four major variants. The CFM56 first ran in 1974.Bilien, J. and Matta, R. (1989). ''The CFM ...

Airbus A320 Family
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] |
Airbus A340
The Airbus A340 is a long-haul, long-range, wide-body passenger airliner that was developed and produced by Airbus. In the mid-1970s, Airbus conceived several derivatives of the Airbus A300, A300, its first airliner, and developed the A340 quadjet in parallel with the Airbus A330, A330 twinjet. In June 1987, Airbus launched both designs with their first orders and the A340-300 took its maiden flight on 25 October 1991. It was certified along with the A340-200 on 22 December 1992 and both versions entered service in March 1993 with launch customers Lufthansa and Air France. The larger A340-500/600 were launched on 8 December 1997; the A340-600 flew for the first time on 23 April 2001 and entered service on 1 August 2002. Keeping the eight-abreast economy cross-section of the A300, the early A340-200/300 has a similar airframe to the A330. Differences include four CFM56s instead of two high-thrust turbofans to bypass ETOPS restrictions on trans-oceanic routes, and a three-leg ...

CFM International LEAP
The CFM International LEAP ("Leading Edge Aviation Propulsion") is a high-bypass turbofan engine produced by CFM International, a 50–50 joint venture between American GE Aviation and French Safran Aircraft Engines (formerly Snecma). It is the successor of the successful CFM56 and competes with the Pratt & Whitney PW1000G to power narrow-body aircraft. Design The LEAP's basic architecture includes a scaled-down version of Safran's low pressure turbine used on the GEnx engine. The fan has flexible blades manufactured by a resin transfer molding process, which are designed to untwist as the fan's rotational speed increases. While the LEAP is designed to operate at a higher pressure than the CFM56 (which is partly why it is more efficient), CFM plans to set the operating pressure lower than the maximum to maximize the engine's service life and reliability. Currently proposed for the LEAP is a greater use of composite materials, a blisk fan in the compressor, a second-generation ...

General Electric Affinity
The General Electric Affinity was a turbofan developed by GE Aviation for supersonic transports. Launched in May 2017 to power the Aerion AS2 supersonic business jet, its initial design was completed in 2018 before its detailed design in 2020 for the first prototype production. GE Aviation discontinued development of the engine in May 2021. Its high-pressure core is derived from the CFM56, matched to a new twin fan low-pressure section for a reduced bypass ratio better suited to supersonic flight. Development At the May 2017 EBACE, Aerion announced its selection of GE Aviation to power the Aerion AS2 supersonic business jet. GE then launched the Affinity program. The final engine configuration is a core with billions of operational hours – suggesting the CFM56 – and a new low-pressure section optimised for supersonic speed. The Affinity high-pressure core is adapted from the CFM56 and the GE F101/ F110 military engines. In February 2018, Aerion released the GE engine co ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Nozzle
A nozzle is a device designed to control the direction or characteristics of a fluid flow (specially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In a nozzle, the velocity of fluid increases at the expense of its pressure energy. Types Jet A gas jet, fluid jet, or hydro jet is a nozzle intended to eject gas or fluid in a coherent stream into a surrounding medium. Gas jets are commonly found in gas stoves, ovens, or barbecues. Gas jets were commonly used for light before the development of electric light. Other types of fluid jets are found in carburetors, where smooth calibrated orifices are used to regulate the flow of fuel into an engine, and in jacuzzis ...

Components Of Jet Engines
This article briefly describes the components and systems found in jet engines. Major components Major components of a turbojet including references to turbofans, turboprops and turboshafts: *Cold section: **Air intake (inlet) — For subsonic aircraft, the inlet is a duct which is required to ensure smooth airflow into the engine despite air approaching the inlet from directions other than straight ahead. This occurs on the ground from cross winds and in flight with aircraft pitch and yaw motions. The duct length is minimised to reduce drag and weight. Air enters the compressor at about half the speed of sound so at flight speeds lower than this the flow will accelerate along the inlet and at higher flight speeds it will slow down. Thus the internal profile of the inlet has to accommodate both accelerating and diffusing flow without undue losses. For supersonic aircraft, the inlet has features such as cones and ramps to produce the most efficient series of shockwaves which fo ...
