STAL
STAL (Svenska Turbinfabriks AB Ljungström; "Swedish Turbine Manufacturing Co.") was an industrial company established in 1913 in Finspång, Sweden, by the brothers Birger Ljungström, and Fredrik Ljungström, developing the Ljungström turbine. In 1916, STAL became a subsidiary of ASEA. In 1959, the company was merged with ''AB de Laval Steam Turbine'' in Stockholm and formed ''Turbin AB de Laval Ljungström'', which changed its name to ''STAL-LAVAL Turbin AB'' in 1962. After ASEA merged with Brown Boveri to ABB 1988, the name was changed to ''ABB STAL AB''. This company later joined forces with Alstom. Ever since, the business is split between Alstom (Alstom Power Sweden AB) and Siemens (Siemens Industrial Turbomachinery AB). History ''AB Ljungströms Ångturbin'' was formed in 1908 for the production of the Ljungström turbine (later called ''STAL turbine'') and other inventions of the two brothers Birger Ljungström (1872-1948) and Fredrik Ljungström (1875-1964). ...

Fredrik Ljungström
Fredrik Ljungström (16 June 1875 – 18 February 1964) was a Swedish engineer, technical designer, and industrialist. Considered one of the foremost inventors of Sweden, Fredrik Ljungström accounted for hundreds of technical patents alone and in collaboration with his brother Birger Ljungström (1872–1948): from early bicycling free wheeling hubs techniques and mechanical automatic transmissions for vehicles, to steam turbines, air preheaters, and circular arc hulls for sailing boats. He co-founded companies such as The New Cycle Company, Ljungström Steam Turbine Co. and Ljungström Swedish Turbine Manufacturing Co. (STAL), and associated with other industrialists such as Alfred Nobel, Helge Palmcrantz, Gustaf de Laval, Curt Nicolin, and Gustaf Dalén. As innovative as his ideas were in function, they also often turned out in terms of unconventional external design, such as his steam turbine locomotives and sailboats. During the resource scarcity of World War II, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ljungström Turbine
The Ljungström turbine (''Ljungströmturbinen'') is a steam turbine. It is also known as the STAL turbine, from the company name STAL ( sv, Svenska Turbinfabriks Aktiebolaget Ljungström). The technology has had numerous uses since its conception, from power plants to vehicles as large as the supertanker '' Seawise Giant''. It was invented circa 1908 by the Swedish brothers Birger Ljungström (1872–1948) and Fredrik Ljungström (1875–1964). The Ljungström brothers were creative, versatile inventors, typical of the 19th century. They not only named the turbine type, but also an early form of a bicycle. Functionality The steam flows through the machine in a radial direction from the centre to the outer extremities. The turbine consists of two halves that rotate against each other. As a result, each rotor blade of the one turbine half serves simultaneously as the guide blade of the other half. The different direction of rotation of the two halves is either compensate ...

Curt Nicolin
Curt René Nicolin (10 March 1921 – 8 September 2006) was a Swedish businessman. He served as the chairman of ASEA and the Swedish Employers Association. Early life Nicolin was born on 10 March 1921 in Stockholm, Sweden, the son of Felix Nicolin and his wife Anna Lisa (née Rehné). He passed ''studentexamen'' at Sigtunaskolan Humanistiska Läroverket in 1941 and graduated from the Royal Institute of Technology in 1945. Career Nicolin was recruited by the Wallenberg family as an engineer at Svenska Turbinfabriks AB Ljungström (STAL) in Finspång the same year, to lead the development of a Swedish jet engine. He got acquainted with Fredrik Ljungström, thanks to whom he debuted at the Nobel Banquet, and for whom he later authored an obituary. Nicolin became vice CEO and technical manager there in 1953. Nicolin was CEO of STAL from 1955 to 1959 and of Turbin AB de Laval Ljungström from 1959 to 1961. In 1961, the Wallenberg family appointed Nicolin as CEO of ASEA, the crown je ...

Finspång
Finspång () is a locality and the seat of Finspång Municipality, Östergötland County, Sweden with 12,440 inhabitants in 2010. Overview Finspång is a traditional industrial town. The first industries were established in 1580 when a Royal factory for cannon and cannon balls was chartered. The industry was to continue for 300 years under supervision of the Walloon/Dutch family De Geer. Anders Qvarfordt was employed by Count Louis de Geer. His assignment was "to lodge and feed the Count de Geers Vallon blacksmiths". Finspång Castle was built by Louis De Geer (1622–1695), and around it industries and an orangery developed into the town of Finspång. In the late 19th century Bofors steel works, which initially supplied forgings and castings to the factory, started to expand into the weapons business. With Alfred Nobel's help, by the 1911 AB Bofors-Gullspång had outcompeted, bought and closed down its competitor. When in 1913 a turbine plant STAL was founded in the town, ...

Northern Europe
The northern region of Europe has several definitions. A restrictive definition may describe Northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54th parallel north, 54°N, or may be based on other geographical factors such as climate and ecology. Climate The climate is mainly Oceanic climate (Cfb), Humid continental climate (Dfb), Subarctic climate (Dfc and Dsc) and Tundra (ET). Geography Northern Europe might be defined roughly to include some or all of the following areas: British Isles, Fennoscandia, the peninsula of Jutland, the Baltic region, Baltic plain that lies to the east and the many islands that lie offshore from mainland Northern Europe and the main European continent. In some cases, Greenland is also included, although it is only politically European, comprising part of the Kingdom of Denmark, and not considered to be geographically in Europe.

Jet Engines
A jet engine is a type of reaction engine discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition can include rocket, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine such as a turbojet, turbofan, ramjet, or pulse jet. In general, jet engines are internal combustion engines. Airbreathing jet engines typically feature a rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex high-bypass turbofan engines. They give higher speed and greater fuel efficiency than piston and propeller aeroengines over long distances.
