György Jendrassik
György Jendrassik or in English technical literature: George Jendrassik (1898 Budapest – 1954 London) was a Hungarian physicist and mechanical engineer. Jendrassik completed his education at Budapest's József Technical University, then at the University of Berlin attended lectures of the famous physicists Albert Einstein and Max Planck. In 1922 he obtained his diploma in mechanical engineering in Budapest. From 1927 he worked at Ganz Rt, where he helped to develop diesel engines, of which the first few pieces were made with single and double cylinders; later, the 4- and 6-cylinder four-stroke versions were developed, without compression and with mixing chamber. Diesel Engines He started working at Ganz and Company - Danubius Electricity, Machine, Waggon and Shipyard Ltd. He started his activities within the Study Department, which was the development and experimental department. His first work included the strength calculation and preparation of the load tests for the main gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Budapest University Of Technology And Economics
The Budapest University of Technology and Economics ( hu, Budapesti Műszaki és Gazdaságtudományi Egyetem or in short ), official abbreviation BME, is the most significant university of technology in Hungary and is considered the world's oldest institute of technology which has university rank and structure. It was the first institute in Europe to train engineers at university level. It was founded in 1782. More than 110 departments and institutes operate within the structure of eight faculties. About 1100 lecturers, 400 researchers and other degree holders and numerous invited lecturers and practising expert specialists participate in education and research at the Budapest University of Technology and Economics. Approximately 1381 of the university's 21,171 students are foreigners, coming from 50 countries.

Daimler-Benz DB 605
The Daimler-Benz DB 605 is a German aircraft engine built during World War II. Developed from the DB 601, the DB 605 was used from 1942 to 1945 in the Messerschmitt Bf 109 fighter, and the Bf 110 and Me 210C heavy fighters. The DB 610, a pair of DB 605s geared to turn a single output shaft that replaced the similar DB 606, was used in the A-3 and all A-5 variants of Germany's only operational heavy bomber, the Heinkel He 177A. License-built versions of the DB 605 were used in the Macchi C.205, Fiat G.55, Reggiane 2005 and some other Italian aircraft. It was also used in the Swedish SAAB B 18B and initially in the pusher-design SAAB J 21. Approximately 42,400 DB 605s of all kinds were built. Design and development The primary differences between the 605 and 601 were greater displacement, higher revolutions, higher compression ratio and a more powerful supercharger. Engineers determined that the cylinders could be bored out to a larger diameter without seriously affecting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Power Jets
Power Jets was a British company set up by Frank Whittle for the purpose of designing and manufacturing jet engines. The company was nationalised in 1944, and evolved into the National Gas Turbine Establishment. History Founded on 27 January 1936, the company consisted of Whittle, Rolf Dudley-Williams, James Collingwood Tinling, and Lancelot Law Whyte of investment bankers O T Falk & Partners. Initial premises were hired from British Thomson-Houston (BTH) at Rugby, Warwickshire. In addition to the founder members, the company initially 'borrowed' some fitters from BTH to assist in the project and later Power Jets was able to get 'one or two' people on loan from the Royal Air Force. By the beginning of 1940 the company had a total workforce of about twenty five. In 1938 Power Jets had moved from Rugby to BTH's works in Lutterworth. A major breakthrough for the company came in 1940 when at the prompting of Stanley Hooker, Ernest Hives, chairman of Rolls-Royce, visited Lutt ...

Hungarian Academy Of Sciences
The Hungarian Academy of Sciences ( hu, Magyar Tudományos Akadémia, MTA) is the most important and prestigious learned society of Hungary. Its seat is at the bank of the Danube in Budapest, between Széchenyi rakpart and Akadémia utca. Its main responsibilities are the cultivation of science, dissemination of scientific findings, supporting research and development, and representing Hungarian science domestically and around the world. History The history of the academy began in 1825 when Count István Széchenyi offered one year's income of his estate for the purposes of a ''Learned Society'' at a district session of the Diet in Pressburg (Pozsony, present Bratislava, seat of the Hungarian Parliament at the time), and his example was followed by other delegates. Its task was specified as the development of the Hungarian language and the study and propagation of the sciences and the arts in Hungarian. It received its current name in 1845. Its central building was inaugurate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varga RMI-1 X/H
The Varga RMI-1 was a twin-engine turboprop-powered aircraft designed by Hungarian engineer . It was a fighter-bomber intended to test the new turboprop Jendrassik Cs-1 aero engine. Only one prototype was built, as with the signing of a mutual defence pact between Hungary and Germany in June 1941, it was decided to license produce the Daimler-Benz DB 605 piston engine and purchase the Messerschmitt Me 210 fitted with these engines to fill the fighter-bomber requirement. Due to difficulties with the original engines, the sole prototype was re-engined with German Daimler-Benz DB 605s in 1944 and undertook taxiing trials and high speed runs, but was destroyed by Allied bombing in June 1944 before making its first flight. Design The RMI-1 was a low wing, twin-engined aircraft with two turboprop Cs-1 engines slung under the wings. It was designed to have a crew of two or three. The tail section was of the conventional type with a single vertical stabilizer A vertical stabilizer o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Berlin
Humboldt-Universität zu Berlin (german: Humboldt-Universität zu Berlin, abbreviated HU Berlin) is a German public research university in the central borough of Mitte in Berlin. It was established by Frederick William III on the initiative of Wilhelm von Humboldt, Johann Gottlieb Fichte and Friedrich Ernst Daniel Schleiermacher as the University of Berlin () in 1809, and opened in 1810, making it the oldest of Berlin's four universities. From 1828 until its closure in 1945, it was named Friedrich Wilhelm University (german: Friedrich-Wilhelms-Universität). During the Cold War, the university found itself in East Berlin and was ''de facto'' split in two when the Free University of Berlin opened in West Berlin. The university received its current name in honour of Alexander and Wilhelm von Humboldt in 1949.

Budapest
Budapest (, ; ) is the capital and most populous city of Hungary. It is the ninth-largest city in the European Union by population within city limits and the second-largest city on the Danube river; the city has an estimated population of 1,752,286 over a land area of about .

The history of Budapest began when an early Celtic settlement transformed into the Roman town of Aquincum, the capital of Lower Pannonia. The Hungarians arrived in the territory in the late 9th century, but the area was pillaged by the Mongols in 1241–42. Re-established Buda became one of the centres of Renaissance humanist culture by the 15th century. The Battle of Mohács, in 1526, was followed by nearly 150 years of Ottoman rule. After the reconquest of Buda in 1686, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
