György Jendrassik
György Jendrassik or 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, where he attended lectures of the famous physicists Albert Einstein and Max Planck. In 1922, he obtained his diploma in mechanical engineering in Budapest. From 1927 onward, 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 Jendrassik 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 girder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hungarian Academy Of Sciences
The Hungarian Academy of Sciences ( , MTA) is Hungary’s foremost and most prestigious learned society. Its headquarters are located along the banks of the Danube in Budapest, between Széchenyi rakpart and Akadémia utca. The Academy's primary functions include the advancement of scientific knowledge, the dissemination of research findings, the support of research and development, and the representation of science in Hungary both domestically and around the world. History The origins of the Hungarian Academy of Sciences date back to 1825, when Count István Széchenyi offered one year's income from his estate to establish a ''Learned Society''. He made this offer during a session of the Diet in Pressburg (Pozsony, now Bratislava), then the seat of the Hungarian Parliament. Inspired by his gesture, other delegates soon followed suit. The Society’s mission was defined as the development of the Hungarian language and the promotion of sciences and the arts in the Hungarian l ...

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 The origins of Power Jets is closely tied with the pioneering work of the British inventor Frank Whittle. Whittle had been exploring the use of gas turbines as a form of propulsion since the 1920s, having been awarded his first patent on such an engine design in 1930.Buttler 2019, p. 4. On 27 January 1936, Power Jets was founded; it initially consisted of Whittle, Rolf Dudley-Williams, James Collingwood Tinling, and Lancelot Law Whyte of investment bankers O T Falk & Partners. At this point, there was no official backing of the company from any government ministry.Buttler 2019, p. 5. Securing funding was a persistently worrying issue throughout the early development of the engine. Initial premises for the firm were hired from British Thomson-Houston (BTH) ...

Mátyás Rákosi
Mátyás Rákosi (; born Mátyás Rosenfeld; 9 March 1892 – 5 February 1971) was a Hungarian communism, communist politician who was the ''de facto'' leader of Hungary from 1947 to 1956. He served first as General Secretary of the Hungarian Communist Party from 1945 to 1948 and then as General Secretary (later renamed First Secretary) of the Hungarian Working People's Party from 1948 to 1956. Rákosi had been involved in left-wing politics since his youth, and in 1919 was a leading commissar in the short-lived Hungarian Soviet Republic. After the fall of the Communist government, he escaped the country and worked abroad as an agent of the Comintern. He was arrested in 1924 after attempting to return to Hungary and organize the Communist Party underground, and ultimately spent over fifteen years in prison. He became a cause célèbre in the international Communist movement, and the predominantly Hungarian Rákosi Battalion of the International Brigades in the Spanish Civil War ...

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 affectin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Berlin
The Humboldt University of Berlin (, abbreviated HU Berlin) is a public research university in the central borough of Mitte in Berlin, Germany.
