Airport Tegel
Berlin Tegel "Otto Lilienthal" Airport (german: link=no, Flughafen Berlin-Tegel „Otto Lilienthal“) was the primary international airport of Berlin, the federal capital of Germany. The airport was named after aviation pioneer Otto Lilienthal and was the fourth busiest airport in Germany, with over 24 million passengers in 2019. In 2016, Tegel handled over 60% of all airline passenger traffic in Berlin. The airport served as a base for Eurowings, Ryanair as well as easyJet. It featured flights to several European metropolitan and leisure destinations as well as some intercontinental routes. It was situated in Tegel, a section of the northern borough of Reinickendorf, northwest of the city centre of Berlin. Tegel Airport was notable for its hexagonal main terminal building around an open square, which made walking distances as short as from the aircraft to the terminal exit. TXL saw its last flight on 8 November 2020 after all traffic had been transferred gradually t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jungfernheide
Jungfernheide () is an area of forest and heathland located in Berlin in the present-day district of Charlottenburg-Nord, a locality of the borough of Charlottenburg-Wilmersdorf. Formerly a large forested area, it was progressively reduced in size through development and military use. The recently closed Tegel Airport now divides the remainder, with Volkspark Jungfernheide (Jungfernheidepark) to the south, and a larger still-forested region between the airport and Lake Tegel. With the creation of Greater Berlin in 1920, Charlottenburg was joined with the former districts of Heerstraße and Jungfernheide to become the seventh district of Berlin. Name The name of the area is a combination of the word ''Heide'', meaning heath, and ''Jungfer'', meaning "Young noblewoman" or "damsel" (cf. Junker), from the Benedictine convent that existed in Spandau from 1269 until the 16th century and owned the area. The street ''Nonnendamm'' also relates to the nuns of Spandau. History Fo ...

Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudolf Nebel
Rudolf Nebel (21 March 1894 – 18 September 1978) was a spaceflight advocate active in Germany's amateur rocket group, the ''Verein für Raumschiffahrt'' (VfR – "Spaceflight Society") in the 1930s and in rebuilding German rocketry following World War II. Early life and involvement in World War I Nebel was born in Weißenburg. During the First World War he served in the ''Luftstreitkräfte'' as a fighter pilot with Jagdstaffel 5, pioneering the use of unguided air-launched signal rockets as offensive armament from a German fighter aircraft in the Luftstreitkräfte while flying the Halberstadt D.II in early 1916, even forcing down two British aircraft with the improvised rocket armament. Following the war, the former ''Leutnant'' Nebel earned a degree in engineering.Neufeld, M.J. ''Von Braun: Dreamer of Space, Engineer of War''. New York: Knopf, 2007. p 38.

Treaty Of Versailles
The Treaty of Versailles (french: Traité de Versailles; german: Versailler Vertrag, ) was the most important of the peace treaties of World War I. It ended the state of war between Germany and the Allied Powers. It was signed on 28 June 1919 in the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which led to the war. The other Central Powers on the German side signed separate treaties. Although the armistice of 11 November 1918 ended the actual fighting, it took six months of Allied negotiations at the Paris Peace Conference to conclude the peace treaty. The treaty was registered by the Secretariat of the League of Nations on 21 October 1919. Of the many provisions in the treaty, one of the most important and controversial was: "The Allied and Associated Governments affirm and Germany accepts the responsibility of Germany and her allies for causing all the loss and damage to which the Allied and Associated Governments and the ...

Aerial Reconnaissance
Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers. History Early developments After the French Revolution, the new rulers became interested in using the balloon to observe enemy manoeuvres and appointed scientist Charles Coutelle to conduct studies using the balloon ''L'Entreprenant'', the first military reconnaissance aircraft. The balloon found its first use in the 1794 conflict with Austria, where in the Battle of Fleurus they gathered information. Moreover, the presence of the balloon had a demoralizing effect on the Austrian troops, which improved the likelihood of victory for the French troops. To operate such balloons, a new unit of the French military, the French Aerostatic Corps, was established; this organisatio ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Parseval Airships
The Parsevals were 22 airships built between 1909 and 1919 by the Luft-Fahrzeug-Gesellschaft (LFG) following the design of August von Parseval. In the 1920s and 1930s, three more airships were built following the Parseval-Naatz (PN) design. As with the rival Zeppelins, the airships were, in both English and German, referred to by the name of the inventor. (In German, the nouns were masculine, that is, "''der Parseval''", "''der Zeppelin''".) In contrast to the Zeppelins, the Parsevals were non-rigid or semi-rigid airships, with little or no stiffening structure inside the fabric envelope. The Zeppelins had a rigid internal framework made of duralumin. Both types relied on hydrogen gas to provide lift. Experimental airship The ''Versuchsluftschiff'' (meaning experimental airship) was Parseval's first model. It was rebuilt several times. *First flight on 26 May 1906 at Berlin's Tegel, a military field *Pilot: Captain von Krogh *Length: 48 m, Diameter: 4.8 m *Power plant: 62&nb ...

Gross-Basenach
Gross-Basenach or Groß-Basenach is the designation for a series of five so-called M-class German military semi-rigid airships constructed by balloonist Nikolaus Basenach and Major Hans Georg Friedrich Groß (1860–1924) of the Royal Prussian Airship Battalion Nr 2#Lui, Luisenstadt 2008 between 1907 and 1914. They produced one experimental and four military Groß-Basenach types, rebuilding each one several times. In all they were not as successful as Major Groß wished. He was one of the sharpest critics of the Zeppelin airships, but the overall superiority and popularity of the Zeppelins doomed his own airships. Even his more successful competitors, Parseval airships, Parseval and Schütte-Lanz, could not compete with Zeppelin after the war's end. Versuchsluftschiff The ''Versuchluftschiff'' (experimental airship) had a volume of 1,800 cubic metres and had a keel directly under the balloon envelope. It was mostly constructed by the firm Siemens-Schuckert GmbH.#pilot, Pilot und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their glider. After completing design and construction of the ''Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while they waited for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviation History
The history of aviation extends for more than two thousand years, from the earliest forms of aviation such as kites and attempts at tower jumping to supersonic and hypersonic flight by powered, heavier-than-air jets. Kite flying in China dates back to several hundred years BC and slowly spread around the world. It is thought to be the earliest example of man-made flight. Leonardo da Vinci's 15th-century dream of flight found expression in several rational designs, but which relied on poor science. The discovery of hydrogen gas in the 18th century led to the invention of the hydrogen balloon, at almost exactly the same time that the Montgolfier brothers rediscovered the hot-air balloon and began manned flights. Various theories in mechanics by physicists during the same period of time, notably fluid dynamics and Newton's laws of motion, led to the foundation of modern aerodynamics, most notably by Sir George Cayley. Balloons, both free-flying and tethered, began to be used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
