Johanna Weber
Johanna Weber (8 August 1910 – 24 October 2014) was a Germany, German-born British people, British mathematician and aerodynamicist. She is best known for her contributions to the development of the Handley Page Victor bomber and the Concorde. Early life Johanna Weber was born in a family of Walloons, Walloon origin in Düsseldorf, Germany, on August 8, 1910. Her father died in the First World War. As a 'war orphan', Weber was eligible for financial support, and she attended a convent school. In 1929, she began studies in chemistry and mathematics at the University of Cologne, but switched a year later to the University of Göttingen. She graduated with a first class honours degree in 1935, and then trained as a teacher for two years. As she did not join the Nazi party, she was not allowed to join a teaching post. Her remaining family, comprising her mother and sister, were in need of financial support, so she sought employment in the armaments industry. Career Weber joined Kr ...

Johanna Weber 1948
Johanna is a feminine name, a variant form of Joanna that originated in Latin in the Middle Ages, including an -h- by analogy with the Latin masculine name Johannes. The original Greek form ''Iōanna'' lacks a medial /h/ because in Greek Spiritus asper, /h/ could only occur initially. For more information on the name's origin, see the article on Joanna.

Aerodynamics Research Institute
The ''Aerodynamische Versuchsanstalt'' (AVA) in Göttingen was one of the four predecessor organizations of the 1969 founded "German Research and Experimental Institute for Aerospace", which in 1997 was renamed in German Aerospace Center (DLR). History The AVA was created in 1919 from the 1907 Göttingen by Ludwig Prandtl founded "Modellversuchsanstalt für Aerodynamik der Motorluftschiff-Studiengesellschaft". In its founding years, it was still concerned with the development of the "best" form of airship. In 1908, the first wind tunnel was built in Göttingen for tests on models for aviation. In 1915, founded in 1911 Kaiser Wilhelm Society (KWG) and under the direction of Ludwig Prandtl the "Modellversuchsanstalt aerodynamics" was founded in 1919 as the "Aerodynamic Research Institute of the Kaiser Wilhelm Society" (AVA) was transferred to the KWG and converted in 1925 into the "Kaiser Wilhelm Institute for Flow Research linked to the Aerodynamic Research Institute".

Angle Of Attack
In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air. In aerodynamics, angle of attack specifies the angle between the chord line of the wing of a fixed-wing aircraft and the vector representing the relative motion between the aircraft and the atmosphere. Since a wing can have twist, a chord line of the whole wing may not be definable, so an alternate reference line is simply defined. Often, the chord line of the root of the wing is chosen as the reference line. Another choice is to use a horizontal line on the fuselage as the reference line (and also as the longitudinal axis).

Vickers VC10
The Vickers VC10 is a mid-sized, narrow-body long-range British jet airliner designed and built by Vickers-Armstrongs (Aircraft) Ltd and first flown at Brooklands, Surrey, in 1962. The airliner was designed to operate on long-distance routes from the shorter runways of the era and commanded excellent hot and high performance for operations from African airports. The performance of the VC10 was such that it achieved the fastest crossing of the Atlantic by a subsonic jet airliner of 5 hours and 1 minute, a record that was held for 41 years, until February 2020 when a British Airways Boeing 747 broke the record at 4 hours 56 minutes due to Storm Ciara. Only the supersonic Concorde was faster. The VC10 is often compared to the larger Soviet Ilyushin Il-62, the two types being the only airliners to use a rear-engined quad layout. The smaller business jet Lockheed JetStar also has this engine arrangement. Although only a relatively small number of VC10s were built, they provide ...

Inverse Problem
An inverse problem in science is the process of calculating from a set of observations the causal factors that produced them: for example, calculating an image in X-ray computed tomography, source reconstruction in acoustics, or calculating the density of the Earth from measurements of its gravity field. It is called an inverse problem because it starts with the effects and then calculates the causes. It is the inverse of a forward problem, which starts with the causes and then calculates the effects. Inverse problems are some of the most important mathematical problems in science and mathematics because they tell us about parameters that we cannot directly observe. They have wide application in system identification, optics, radar, acoustics, communication theory, signal processing, medical imaging, computer vision, geophysics, oceanography, astronomy, remote sensing, natural language processing, machine learning, nondestructive testing, slope stability analysis and man ...

Frances Bradfield
Frances Beatrice Bradfield (9 October 1895– 26 February 1967) was an aeronautical engineer at the Royal Aircraft Establishment (RAE). She worked at RAE Farnborough, where she headed the Wind Tunnels Section. Here she mentored many of the younger male engineers who joined the RAE. Early life and education Frances Bradfield was born in 1895, in Leicester, and in 1914 "came up" to Newnham College, Cambridge, graduating with a second class BA degree in Mathematics in 1917. Royal Aeronautical Establishment Sometime after graduating from Cambridge, probably around 1919, Bradfield joined the Royal Aircraft Establishment (RAE) at Farnborough, Hampshire, where she spent her entire career research aeronautics and specialising in Wind tunnel research. Bradfield's earliest published research at the RAE - credited gender-ambiguously to "F.B. Bradfield" - was published in December 1919 on "Wind channel test of Bristol Pullman body." During her first decade and beyond, Bradfield publis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enemy Alien
In customary international law, an enemy alien is any native, citizen, denizen or subject of any foreign nation or government with which a domestic nation or government is in conflict and who is liable to be apprehended, restrained, secured and removed. Usually, the countries are in a state of declared war. Australia In Australia, in the wake of the outbreak of World War II, Jewish refugees and others fleeing the Nazis were classified as "enemy aliens" upon their arrival in Australia if they arrived with German identity papers. Australian law in 1939 designated people "enemy aliens" if they were Germans or were Australians who had been born in Germany; later, it covered Italians and Japanese as well. The Australian government would therefore intern them, sometimes for years until the war ended, in camps such as the isolated Tatura Internment Camp 3 D which held approximately 300 internees thus deemed "enemy aliens", mostly families, including children as young as two years of ...

Royal Aircraft Establishment
The Royal Aircraft Establishment (RAE) was a British research establishment, known by several different names during its history, that eventually came under the aegis of the Ministry of Defence (United Kingdom), UK Ministry of Defence (MoD), before finally losing its identity in mergers with other institutions. The first site was at Farnborough Airfield ("RAE Farnborough") in Hampshire to which was added a second site RAE Bedford (Bedfordshire) in 1946. In 1988 it was renamed the Royal Aerospace Establishment (RAE) before merging with other research entities to become part of the new Defence Research Agency in 1991. History In 1904–1906 the Army Balloon Factory, which was part of the Army School of Ballooning, under the command of Colonel James Templer (balloon aviator), James Templer, relocated from Aldershot to the edge of Farnborough Common in order to have enough space to inflate the new "dirigible balloon" or airship which was then under construction.Walker, P; Early Avi ...

Operation Surgeon
Operation Surgeon was a British post-Second World War programme to exploit German aeronautics and deny German technical skills to the Soviet Union. A list of 1,500 German scientists and technicians was created, with the goal of forcibly removing them from Germany ("whether they like it or not") to lessen the risk of their falling into enemy hands. It was feared that if they remained in Germany, they could enable the Soviet Union to "achieve a long range bomber force superior to any other in the world". UK 31 March 2006 At the operation's inception, many of the scientists had already offered their services to British Commonwealth countries, Sweden, Switzerland, Brazil and Sou ...

Operation Paperclip
Operation Paperclip was a secret United States intelligence program in which more than 1,600 German scientists, engineers, and technicians were taken from the former Nazi Germany to the U.S. for government employment after the end of World War II in Europe, between 1945 and 1959. Conducted by the Joint Intelligence Objectives Agency (JIOA), it was largely carried out by special agents of the U.S. Army's Counterintelligence Corps (CIC). Many of these personnel were former members and some were former leaders of the Nazi Party. In February 1945, Supreme Headquarters Allied Expeditionary Force (SHAEF) set up T-Force, or Special Sections Subdivision, which grew to over 2,000 personnel by June. T-Force examined 5,000 German targets with a high priority on synthetic rubber and oil catalysts, new designs in armored equipment, V-2 (rocket) weapons, jet and rocket propelled aircraft, naval equipment, field radios, secret writing chemicals, aero medicine research, gliders, and "scientif ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
