Samsung Aerospace Industries
Samsung Aerospace Ind., Ltd. (SSA; ) was a South Korean aerospace manufacturer. History The company was originally established as Samsung Precision () on 1 August 1977 with initial capital of ₩1 billion, and began constructing its first factory, a facility of , in Changwon, South Gyeongsang Province. In its early history the company manufactured a variety of products including cameras and lead frames, but its business came to focus increasingly on aerospace manufacturing, and so it changed its name to Samsung Aerospace Industries in February 1987. In 1996, SSA was considering to acquire Dutch aircraft manufacturer Fokker, but the plan was scrapped because of the economic problems emerging in South Korea in the late 90s. The company changed its name to Samsung Techwin in March 2000 after its aircraft division was merged into Korea Aerospace Industries (KAI) along with Daewoo Heavy Industries and Hyundai Space and Aircraft in 1999.

Fokker
Fokker (; ) was a Dutch aircraft manufacturer that operated from 1912 to 1996. The company was founded by the Dutch aviator Anthony Fokker and became famous during World War I for its fighter aircraft. During its most successful period in the 1920s and 1930s, Fokker dominated the civil aviation market. The company's fortunes declined over the course of the late 20th century; it declared bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the Fokker Spin, ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized on having sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stringer (aircraft)
In engineering, a longeron or stringer is a load-bearing component of a framework. The term is commonly used in connection with aircraft fuselages and automobile chassis. Longerons are used in conjunction with stringers to form structural frameworks. Aircraft In an aircraft fuselage, stringers are attached to formers (also called frames) and run in the longitudinal direction of the aircraft. They are primarily responsible for transferring the aerodynamic loads acting on the skin onto the frames and formers. In the wings or horizontal stabilizer, longerons run spanwise (from wing root to wing tip) and attach between the ribs. The primary function here also is to transfer the bending loads acting on the wings onto the ribs and spar. The terms "longeron" and "stringer" are sometimes used interchangeably. Historically, though, there is a subtle difference between the two terms. If the longitudinal members in a fuselage are few in number (usually 4 to 8) and run all along the f ...

General Electric CF6
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 McDonne ...

F404
The General Electric F404 and F412 are a family of afterburning turbofan engines in the class (static thrust). The series is produced by GE Aerospace. Partners include Volvo Aero, which builds the RM12 variant. The F404 was developed into the larger F414 turbofan, as well as the experimental GE36 civil propfan. Design and development F404 GE developed the F404 for the F/A-18 Hornet, shortly after losing the competition for the F-15 Eagle's engine to Pratt & Whitney, and losing the Lightweight Fighter (LWF) competition to the Pratt & Whitney F100 powered YF-16. For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from 0.20 to 0.34 to enable higher fuel efficiency. The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum thrust of 16,000 lbf (71.2 kN) in the original F404-GE-400 model.

LM2500
The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation. The LM2500 is a derivative of the General Electric CF6 aircraft engine. As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power warships. Other uses include hydrofoils, hovercraft and fast ferries. In 2012, GE developed an FPSO version to serve the oil and gas industry's demand for a lighter, more compact version to generate electricity and drive compressors to send natural gas through pipelines. Design and development The LM2500 was first used on the US Navy in 1969, after the original FT-4 gas turbines experienced many technical problems. Later, they were used in US Navy warships in the of destroyers and the related , which were constructed from 1970. In this configuration it was rated to . This configuration was subsequently used into the 1980s in the s, and s. It was also used by one of People's R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
