Ægidius Elling
Jens William Ægidius Elling (also Aegidus or Aegidius) (26 July 1861 – 27 May 1949) was a Norwegian researcher, inventor and pioneer of gas turbines who is considered to be the father of the gas turbine. He built the first gas turbine that was able to produce more power than needed to run its own components. Elling was born in and grew up in Oslo, Norway. He studied mechanical engineering at Kristiania Technical College, (now part of Oslo and Akershus University College of Applied Sciences) graduating in 1881. Between 1885 and 1902, he worked as an engineer and designer at a number of workshops in Sweden and Norway. His first gas turbine patent was granted in 1884. In 1903 he completed the first turbine that produced excess power; his original machine used both rotary compressors and turbines to produce net. He further developed the concept, and by 1912 he had developed a gas turbine system with separate turbine unit and compressor in series, a combination that is now c ...

Aegidius Elling
Aegidius (died 464 or 465) was the ruler of the short-lived Kingdom of Soissons from 461 to 464/465AD. Before his ascension, he became ''magister militum per Gallias'' (Master of the Soldiers for Gaul) serving under Majorian, in 458AD. An ardent supporter of Majorian, Aegidius rebelled against Ricimer when he assassinated Majorian and replaced him with Libius Severus; Aegidius may have pledged his allegiance to Leo I, the Eastern Roman Emperor. Aegidius repeatedly threatened to invade Italy and dethrone Libius Severus, but never actually launched such an invasion; historians have suggested he was unwilling to launch an invasion due to the pressure of the Visigoths, or else because it would leave Gaul exposed. Aegidius launched several campaigns against the Visigoths and the Burgundians, recapturing Lyons from the Burgundians in 458, and routing the Visigoths at the Battle of Orleans. He died suddenly after a major victory against the Visigoths; ancient historians say that he was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater ...

Oslo
Oslo ( , , or ; sma, Oslove) is the capital and most populous city of Norway. It constitutes both a county and a municipality. The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of in 2019, and the metropolitan area had an estimated population of in 2021. During the Viking Age the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in 1040 under the name Ánslo, and established as a ''kaupstad'' or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in honour of the king. It became a municipality ('' formannskapsdistrikt'') on 1 January 1838. The city fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gas Compressor
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. The main distinction is that the focus of a compressor is to change the density or volume of the fluid, which is mostly only achievable on gases. Gases are compressible, while liquids are relatively incompressible, so compressors are rarely used for liquids. The main action of a pump is to pressurize and transport liquids. Many compressors can be staged, that is, the fluid is compressed several times in steps or stages, to increase discharge pressure. Often, the second stage is physically smaller than the primary stage, to accommodate the already compressed gas without reducing its pressure. Each stage further compresses the gas and increases its pressure and also temperature (if inter cooling between stages i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Whittle
Air Commodore Sir Frank Whittle, (1 June 1907 – 8 August 1996) was an English engineer, inventor and Royal Air Force (RAF) air officer. He is credited with inventing the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention which was technically unfeasible at the time. Whittle's jet engines were developed some years earlier than those of Germany's Hans von Ohain, who designed the first-to-fly (but never operational) turbojet engine. Whittle demonstrated an aptitude for engineering and an interest in flying from an early age. At first he was turned down by the RAF but, determined to join the force, he overcame his physical limitations and was accepted and sent to No. 2 School of Technical Training to join No 1 Squadron of Cranwell Aircraft Apprentices. He was taught the theory of aircraft engines and gained practical experience in the engineering workshops. His academic and practical abilities as an Aircraft Apprentice earned him a place ...

Jet Engine
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, Pump-jet, 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 engine, pulse jet. In general, jet engines are internal combustion engines. Airbreathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, 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, high-bypass turbofan engines. They give higher speed and greater fuel eff ...

Aschehoug
H. Aschehoug & Co. (W. Nygaard), commonly known as Aschehoug,() is one of the largest independent publishing companies in Norway, founded in 1872. Headquartered in Oslo, the publishing house has 480 employees. The Aschehoug group also comprises other publishing houses owned partially or wholly by Aschehoug. Aschehoug can be directly translated to "ash hill." History Aschehoug was founded as a bookstore in 1872 on Egertorvet in Oslo by cousins, Hieronymus and Halvard Aschehoug. From the start the firm was involved in publishing in a modest way, its output consisting mainly of school books. In 1888, the company was taken over by William Martin Nygaard and Thorstein Lambrechts (1856-1933), who kept the name while expanding its operations. In 1900 William Nygaard withdrew from the bookselling side of the business and established a publishing company, which was given the name H. Aschehoug & Co. (W. Nygaard). In 1935, following the death of William Nygaard, the publishing house turne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
