gas turbine

A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in between.
The basic operation of the gas turbine is similar to that of the steam power plant except that air is used instead of water. Fresh atmospheric air flows through a compressor that brings it to higher pressure. Energy is then added by spraying fuel into the air and igniting it so the combustion generates a high-temperature flow. This high-temperature high-pressure gas enters a turbine, where it expands down to the exhaust pressure, producing a shaft work output in the process. The turbine shaft work is used to drive the compressor and other devices such as an electric generator that may be coupled to the shaft. The energy that is not used for shaft work comes out in the exhaust gases, so these have either a high temperature or a high velocity. The purpose of the gas turbine determines the design so that the most desirable energy form is maximized. Gas turbines are used to power aircraft, trains, ships, electrical generators, or even tanks.〔(''Introduction to Engineering Thermodynamics'' ), Richard E. Sonntag, Claus Borrgnakke 2007.

*50: Hero's Engine (''aeolipile'') — Apparently, Hero's steam engine was taken to be no more than a toy, and thus its full potential not realized for centuries.
*1500: The "Chimney Jack" was drawn by Leonardo da Vinci: Hot air from a fire rises through a single-stage axial turbine rotor mounted in the exhaust duct of the fireplace and turning the roasting spit by gear/ chain connection.
*1629: Jets of steam rotated an impulse turbine that then drove a working stamping mill by means of a bevel gear, developed by Giovanni Branca.
*1678: Ferdinand Verbiest built a model carriage relying on a steam jet for power.
*1791: A patent was given to John Barber, an Englishman, for the first true gas turbine. His invention had most of the elements present in the modern day gas turbines. The turbine was designed to power a horseless carriage.
*1861: British patent no. 1633 was granted to Marc Antoine Francois Mennons for a "Caloric engine". The patent shows that it was a gas turbine and the drawings show it applied to a locomotive.〔http://worldwide.espacenet.com/publicationDetails/originalDocument?CC=GB&NR=186101633A&KC=A&FT=D&ND=3&date=18611218&DB=EPODOC&locale=en_EP〕 Also named in the patent was Nicolas de Telescheff (otherwise Nicholas A. Teleshov), a Russian aviation pioneer.〔http://translate.google.com/translate?hl=en&sl=ru&u=http://www.maria-online.com/information/article.php%3Fq%3D%25D0%25A2%25D0%25B5%25D0%25BB%25D0%25B5%25D1%2588%25D0%25BE%25D0%25B2,_%25D0%259D%25D0%25B8%25D0%25BA%25D0%25BE%25D0%25BB%25D0%25B0%25D0%25B9_%25D0%2590%25D1%2584%25D0%25B0%25D0%25BD%25D0%25B0%25D1%2581%25D1%258C%25D0%25B5%25D0%25B2%25D0%25B8%25D1%2587&prev=/search%3Fq%3DNicolas%2Bde%2BTelescheff%2Baviation%26client%3Dfirefox-a%26hs%3DXNZ%26rls%3Dorg.mozilla:en-US:official%26biw%3D1023%26bih%3D698〕
*1872: A gas turbine engine was designed by Franz Stolze, but the engine never ran under its own power.
*1894: Sir Charles Parsons patented the idea of propelling a ship with a steam turbine, and built a demonstration vessel, the ''Turbinia'', easily the fastest vessel afloat at the time. This principle of propulsion is still of some use.
*1895: Three 4-ton 100 kW Parsons radial flow generators were installed in Cambridge Power Station, and used to power the first electric street lighting scheme in the city.
*1899: Charles Gordon Curtis patented the first gas turbine engine in the USA ("Apparatus for generating mechanical power", Patent No. US635,919).〔(【引用サイトリンク】title=Patent US0635919 )
*1900: Sanford Alexander Moss submitted a thesis on gas turbines. In 1903, Moss became an engineer for General Electric's Steam Turbine Department in Lynn, Massachusetts.〔Leyes, p.231-232.〕 While there, he applied some of his concepts in the development of the turbosupercharger. His design used a small turbine wheel, driven by exhaust gases, to turn a supercharger.〔
*1903: A Norwegian, Ægidius Elling, was able to build the first gas turbine that was able to produce more power than needed to run its own components, which was considered an achievement in a time when knowledge about aerodynamics was limited. Using rotary compressors and turbines it produced 11 hp (massive for those days).〔Bakken, Lars E et al, p.83-88.

*1920s The practical theory of gas flow through passages was developed into the more formal (and applicable to turbines) theory of gas flow past airfoils by A. A. Griffith resulting in the publishing in 1926 of ''An Aerodynamic Theory of Turbine Design''. Working testbed designs of axial turbines suitable for driving a propellor were developed by the Royal Aeronautical Establishment proving the efficiency of aerodynamic shaping of the blades in 1929.
