Hermann Schlichting
Hermann Schlichting (22 September 1907 – 15 June 1982) was a German fluid dynamics engineer. Life and work Hermann Schlichting studied from 1926 till 1930 mathematics, physics and applied mechanics at the University of Jena, Vienne and Göttingen. In 1930 he wrote his PhD in Göttingen titled ''Über das ebene Windschattenproblem'' and also in the same year passed the state examination as teacher for higher mathematics and physics. His meeting with Ludwig Prandtl had a long-lasting effect on him. He worked from 1931 till 1935 at the Kaiser Wilhelm Institute for Flow Research in Göttingen. His main research area was fluid flows with viscous effects. Simultaneously he also started working on airfoil aerodynamics. In 1935 Schlichting went to Dornier in Friedrichshafen. There he did the planning for the new wind tunnel and after short construction time took charge over it. With it he gained useful experience in the field of aerodynamics. At the age of 30 in 1937 he joined T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balje, Lower Saxony
Balje is a municipality in the district of Stade, in Lower Saxony, Germany. It belonged to the Prince-Archbishopric of Bremen.

Fluid Dynamics
In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids— liquids and gases. It has several subdisciplines, including ''aerodynamics'' (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and ti ...

Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Friedrichshafen
Friedrichshafen ( or ; Low Alemannic: ''Hafe'' or ''Fridrichshafe'') is a city on the northern shoreline of Lake Constance (the ''Bodensee'') in Southern Germany, near the borders of both Switzerland and Austria. It is the district capital (''Kreisstadt'') of the Bodensee district in the federal state of Baden-Württemberg. Friedrichshafen has a population of about 58,000. History 19th and early 20th century Friedrichshafen was established in 1811 as part of the new Kingdom of Württemberg, an ally of France during the Napoleonic Wars. It was named for King Frederick I of Württemberg, who privileged it as a free port and transshipment point for the kingdom's Swiss trade. Friedrichshafen was created from the former city of Buchhorn, whose coat of arms it adopted. The new city also incorporated the former village of Hofen, whose monastery was refurbished to serve as the summer residence of the Württemberger kings. King William I continued improving the city, including the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dornier Flugzeugwerke
Dornier Flugzeugwerke was a German aircraft manufacturer founded in Friedrichshafen in 1914 by Claude Dornier. Over the course of its long lifespan, the company produced many designs for both the civil and military markets. History Originally Dornier Metallbau, Dornier Flugzeugwerke took over Flugzeugbau Friedrichshafen production facilities ( Weingarten, Warnemünde, and the former Zeppelin shed at Manzell) when it failed in 1923. Dornier was well known between the two world wars as a manufacturer of large, all-metal flying boats and of land based airliners. The record-breaking 1924 Wal ( en, Whale) was used on many long distance flights and the Do X set records for its immense size and weight. Dornier's successful landplane airliners, including the Komet (''Comet'') and Merkur (''Mercury''), were used by Lufthansa and other European carriers during the 1920s and early 30s. Dornier built its aircraft outside Germany during much of this period due to the restrictions place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis fo ...

Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the r ...

Kaiser Wilhelm Institute
The Kaiser Wilhelm Society for the Advancement of Science (German: ''Kaiser-Wilhelm-Gesellschaft zur Förderung der Wissenschaften'') was a German scientific institution established in the German Empire in 1911. Its functions were taken over by the Max Planck Society. The Kaiser Wilhelm Society was an umbrella organisation for many institutes, testing stations, and research units created under its authority. Constitution The Kaiser Wilhelm Gesellschaft (KWG) was founded in 1911 in order to promote the natural sciences in Germany, by founding and maintaining research institutions formally independent from the state and its administrations. The institutions were to be under the guidance of prominent directors, which included the physicists and chemists Walther Bothe, Peter Debye, Albert Einstein, Fritz Haber and Otto Hahn; a board of trustees also provided guidance. Funding was ultimately obtained from sources internal and external to Germany. Internally, money was raised f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
