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 Sailboat
Ljungström sailboats were created by the Swedish engineer Fredrik Ljungström, who was interested in sailing since childhood. A "Ljungström sailboat" typically has a "circular arc" hull and a "Ljungström rig". A Ljungström rig mast has no mast stays. The mast rotates on two ball bearings often flying double mainsails, with no foresails. In their time the Ljungström sailboats were a minor revolution as they were fast, safe and easy to sail as well as relatively easy and affordable to produce. The models were named The Wing and the number (Swedish Vingen 1, Vingen 2 etc.) chronologically. A few models were built in series, such as Vingen 11A and the Twin Wing which was specifically produced for the US market. The design was not appreciated by the fairly conservative yacht clubs at the time, so development was done with scarce means. Approximately sixty boats (of different sizes) were produced. Approximately eighteen are known to still exist; a dozen of those are sailing, ... [...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 ...

Asea Stal
STAL (Svenska Turbinfabriks AB Ljungström; "Swedish Turbine Manufacturing Co.") was an industrial company A company, abbreviated as co., is a Legal personality, legal entity representing an association of people, whether Natural person, natural, Legal person, legal or a mixture of both, with a specific objective. Company members share a common p ... 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). Hi ...
