General Electric CF6-80C2
The General Electric CF6, US military designations F103 and F138, is a family of high-bypass turbofan engines produced by GE Aviation. Based on the TF39, the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners. The basic engine core also powers the LM2500 and LM6000 marine and power generation turboshafts. It is gradually being replaced by the newer GEnx family. Development After developing the TF39 for the C-5 Galaxy in the late 1960s, GE offered a more powerful variant for civilian use, the CF6. GE quickly found interest in two designs being offered for a recent Eastern Airlines contract, the Lockheed L-1011 and the McDonnell Douglas DC-10. Lockheed eventually selected the Rolls-Royce RB211, but the latter stuck with the CF6 and entered service in 1971. It was also selected for versions of the Boeing 747. Since then, the CF6 has powered versions of the Airbus A300, A310 and A330, Boeing 767, Lockheed C-5M Galaxy, and McDonnel ...

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaft horsepower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the Gas compressor, compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Express Delivery
Express mail is an expedited mail delivery service for which the customer pays a premium for faster delivery.

Aircraft Maintenance
Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair. Regulation The maintenance of aircraft is highly regulated, in order to ensure safe and correct functioning during flight. In civil aviation national regulations are coordinated under international standards, established by the International Civil Aviation Organization (ICAO). The ICAO standards have to be implemented by local airworthiness authorities to regulate the maintenance tasks, personnel and inspection system. Maintenance staff must be licensed for the tasks they carry out. Major airworthiness regulatory authorities include the US Federal Aviation Administration (FAA), European Union Aviation Safety Agency (EASA), Australian Transport Safety Bureau (ATSB), Transport Canada (TC) and I ...

GEnx
GenX is a Chemours trademark name for a synthetic, short-chain organofluorine chemical compound, the ammonium salt of hexafluoropropylene oxide dimer acid (HFPO-DA). It can also be used more informally to refer to the group of related fluorochemicals that are used to produce GenX. DuPont began the commercial development of GenX in 2009 as a replacement for perfluorooctanoic acid (PFOA, also known as C8), in response to legal action due to the health effects and ecotoxicity of PFOA. Although GenX was designed to be less persistent in the environment compared to PFOA, its effects may be equally harmful or even more detrimental than those of the chemical it was meant to replace. GenX is one of many synthetic organofluorine compounds collectively known as per- and polyfluoroalkyl substances (PFASs). Uses The chemicals are used in products such as food packaging, paints, cleaning products, non-stick coatings, outdoor fabrics and firefighting foam. The chemicals are manufactured b ...

GE90
The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aerospace for the Boeing 777, with thrust ratings from . It entered service with British Airways in November 1995. It is one of three engines for the 777-200 and -200ER, and the exclusive engine of the -200LR, -300ER, and 777F. It was the largest jet engine, until being surpassed in January 2020 by its successor, the GE9X, which has a larger fan diameter by . However, the GE90-115B, the most recent variant of the GE90, is rated for a higher thrust (115,000 lbs) than the GE9X. Background In the early 1980s, GE began to develop an unducted fan (UDF) engine, which was thought to be a more fuel-efficient option to propel short-haul airliners, a compelling proposition after the 1979 oil crisis. NASA gave GE a grant in February 1984 to continue its research, eventually building the experimental GE36. One of the major innovations for the engine were its carbon fiber composite fan blades, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rolls-Royce RB211
The Rolls-Royce RB211 is a British family of high-bypass turbofan engines made by Rolls-Royce Holdings, Rolls-Royce. The engines are capable of generating of thrust. The RB211 engine was the first production turbofan#Three-spool, three-spool engine and turned Rolls-Royce from a significant player in the aero-engine industry into a global leader. Originally developed for the Lockheed L-1011 TriStar, it entered service in 1972 and was the exclusive engine to power the L-1011. Mismanagement of the initial development and consequent cost issues led to the effective nationalisation of Rolls-Royce Limited, to save the workforce and the engine businesses important to the UK and many other aerospace and aircraft operating companies. In the early 1970s, the engine was reckoned by the company to be capable of at least 50 years of continuous development. The RB.211 was renamed, in 1989, to become the basis of the Rolls-Royce Trent family of engines when the RB211-524L was renamed to the ...

Eastern Airlines
Eastern Air Lines (also colloquially known as Eastern) was a major airline in the United States that operated from 1926 to 1991. Before its dissolution, it was headquartered at Miami International Airport in an unincorporated area of Miami-Dade County, Florida. Eastern was one of the " Big Four" domestic airlines created by the Spoils Conferences of 1930, and was headed in its early years by World War I flying ace Eddie Rickenbacker. It had a near monopoly in air travel between New York and Florida from the 1930s until the 1950s and dominated this market for decades afterward. During airline deregulation in the late 1970s and early 1980s, labor disputes and high debt loads strained the company under the leadership of former astronaut Frank Borman. Frank Lorenzo acquired Eastern in 1985 and moved many of its assets to his other airlines, including Continental Airlines and Texas Air Corporation. After continued labor disputes and a crippling strike in 1989, Eastern ran out o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
