Hans Grade
Hans Grade (May 17, 1879 – October 22, 1946) was a German aviation pioneer. Hans Grade was born in Köslin, Pomerania. On 28 October 1908 he successfully conducted the first motor-flight over German soil in a motorised triplane aircraft of his own construction at Magdeburg. A year later, on 30 October 1909, flying a new monoplane design he won the 40.000 Reichsmark "Lanz-Preis der Lufte", for the first German to fly a flat "8" in a German aircraft with German engine around two pylons 1000 meters apart. In 1910 he established the first aviation school in Germany. A Grade monoplane carried Germany's first air mail, when pilot Pentz made a flight from Bork to Bruck in February 1912 with a small sack of mail in his lap. Although successful, Grade monoplanes did not become as famous as many contemporary European designs, and for this reason comparatively few were built. In 1921 he established an automobile company called " Grade Automobilwerke AG", which produced small, 2 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesarchiv Bild 183-R00490, Hans Grade
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the y ...

Aviation
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the '' Wright Flyer'', the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet engine which enabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Triplane
A triplane is a fixed-wing aircraft equipped with three vertically stacked wing planes. Tailplanes and canard (aeronautics), canard foreplanes are not normally included in this count, although they occasionally are. Design principles The triplane arrangement may be compared with the biplane in a number of ways. A triplane arrangement has a narrower wing Chord (aircraft), chord than a biplane of similar span and area. This gives each wing-plane a slender appearance with higher aspect ratio, making it more efficient and giving increased lift. This potentially offers a faster rate of climb and tighter turning radius, both of which are important in a fighter. The Sopwith Triplane was a successful example, having the same wing span as the equivalent biplane, the Sopwith Pup. Alternatively, a triplane has reduced span compared to a biplane of given wing area and aspect ratio, leading to a more compact and lightweight structure. This potentially offers better maneuverability for a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magdeburg
Magdeburg (; ) is the Capital city, capital of the Germany, German States of Germany, state Saxony-Anhalt. The city is on the Elbe river. Otto I, Holy Roman Emperor, Otto I, the first Holy Roman Emperor and founder of the Archbishopric of Magdeburg, was buried in the city's Magdeburg Cathedral, cathedral after his death. Magdeburg's version of German town law, known as Magdeburg rights, spread throughout Central Europe, Central and Eastern Europe. In the Late Middle Ages, Magdeburg was one of the largest and most prosperous German cities and a notable member of the Hanseatic League. One of the most notable people from the city was Otto von Guericke, famous for his experiments with the Magdeburg hemispheres. Magdeburg has experienced three major devastations in its history. In 1207 the first catastrophe struck the city, with a fire burning down large parts of the city, including the Magdeburg Cathedral#Previous building, Ottonian cathedral. The Catholic League (German), Catholi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade Monoplane
The Grade monoplane was a single-seat aircraft constructed by Hans Grade in 1909. It was the first successful heavier-than-air aircraft produced in Germany, and around 80 were eventually built. Design and development The aircraft was a high-wing monoplane, with the pilot sitting below the wing. A pair of inverted V struts formed the fabric-covered cabane structure which carried the upper bracing wires: the front struts were continued below the wing, with the forward struts bearing the mainwheels. An elongated cruciform tail unit was attached to the end of a single boom by a universal joint immediately behind the single tailwheel. Lateral control was effected by wing-warping. It was powered by a 12 kW (18 hp) two-stroke air-cooled V-4 engine, also built by Grade, which drove a two-bladed aluminium bladed propeller. Operational history The aircraft was first flown on 17 August 1909 A series of longer flights were made in September, and on October 30 Grade won the La ...

Treaty Of Versailles
The Treaty of Versailles was a peace treaty signed on 28 June 1919. As the most important treaty of World War I, it ended the state of war between Germany and most of the Allies of World War I, Allied Powers. It was signed 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 with Germany (Compiègne), armistice of 11 November 1918 ended the actual fighting, and agreed certain principles and conditions including the payment of reparations, it took six months of Allied negotiations at the Paris Peace Conference (1919–1920), Paris Peace Conference to conclude the peace treaty. Germany was not allowed to participate in the negotiations before signing the treaty. The treaty German disarmament, required Germany to disarm, make territorial concessions, extradite alleged war criminals, agree to Kaiser Wilhelm being p ...

Volksflugzeug
The ''Volksflugzeug'' (People's Aircraft) was a grand Nazi Germany, Nazi-era scheme for the mass-production of a small and simple airplane in the 1930s. It was one of the attempts of the Nazi regime to use consumer technologies as a propaganda tool. Unlike the Volkswagen Beetle, Volkswagen car, the showpiece of the Nazis’ attempt to appear to work for the good of the average German, as well as the less-known ''Volksempfänger'' radio, the ' refrigerator and the ' gas mask, the ''Volksflugzeug'' project was contemplated but never fully realized. The ''Volksflugzeug'' grand plan surfaced at different times and in different locations in Germany during Nazi rule. However, since it only had lukewarm official backing, it remained ill-defined and vague. World War II necessitated a change in priorities that abruptly ended most of the projects connected with the scheme. History Early attempts The idea of a "People's Aircraft" predated the Nazi regime. Its main source of inspiration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin Tempelhof Airport
Berlin Tempelhof Airport () was one of the first airports in Berlin, Germany. Situated in the south-central Berlin borough of Tempelhof-Schöneberg, the airport ceased operating in 2008 amid controversy, leaving Tegel and Schönefeld as the two main airports serving the city for another twelve years until both were replaced by Berlin Brandenburg Airport in 2020. Tempelhof was designated as an airport by the Reich Ministry of Transport on 8 October 1923. The old terminal was originally constructed in 1927. In anticipation of increasing air traffic, the Nazi government began an enormous reconstruction in the mid-1930s. While it was occasionally cited as the world's oldest operating commercial airport, the title was disputed by several other airports, and is no longer an issue since its closure. Tempelhof was one of Europe's three iconic pre-World War II airports, the others being London's now defunct Croydon Airport and the old Paris–Le Bourget Airport. It acquired a furth ...
