Hans Gustav Röhr
Hans Gustav Röhr (10 February 1895 – 10 August 1937) was a German aviation pioneer. After the First World War international treaty obligations imposed on Germany made this impossible and he applied his talents to automobiles. In 1926 he founded his own automobile manufacturing business, but this succumbed to bankruptcy in 1931. After that he worked for Adler. Here his responsibilities included design and development of new models. One of the cars he designed and developed, launched in 1932, was the Adler Trumpf which was both technologically innovative and successful commercially. He moved, as Technical Director, to Daimler-Benz in 1935, but his career was cut short by Pneumonia to which he succumbed, according to at least one report, after a drive in an open-topped car, and as a result of which he died. Biography Provenance and early years Hans Gustav Röhr was born at Uerdingen near Krefeld (into which it has subsequently been subsumed), close to the River Rhine. His ...

Aviation
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft 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. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of 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 which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Straight Engine
The straight or inline engine is an internal combustion engine with all cylinders aligned in one row and having no offset. Usually found in four, six and eight cylinder configurations, they have been used in automobiles, locomotives and aircraft, although the term in-line has a broader meaning when applied to aircraft engines, see Inline engine (aviation). Design A straight engine is considerably easier to build than an otherwise equivalent horizontally opposed or V engine, because both the cylinder bank and crankshaft can be milled from a single metal casting, and it requires fewer cylinder heads and camshafts. In-line engines are also smaller in overall physical dimensions than designs such as the radial, and can be mounted in any direction. Straight configurations are simpler than their V-shaped counterparts. Although six-cylinder engines are inherently balanced, the four-cylinder models are inherently off balance and rough, unlike 90-degree V fours and horizontally oppos ...

Occupation Of The Rhineland
The Occupation of the Rhineland from 1 December 1918 until 30 June 1930 was a consequence of the collapse of the Imperial German Army in 1918, after which Germany's provisional government was obliged to agree to the terms of the 1918 armistice. This included accepting that the troops of the victorious powers occupied the left bank of the Rhine and four right bank "bridgeheads" with a radius around Cologne, Koblenz, Mainz and a radius around Kehl. Furthermore, the left bank of the Rhine and a strip east of the Rhine was declared a demilitarized zone. The Treaty of Versailles repeated these provisions, but limited the presence of the foreign troops to fifteen years after the signing of the treaty (until 1934). The purpose of the occupation was on the one hand to give France security against a renewed German attack, and on the other to serve as a guarantee for reparations obligations. After this was apparently achieved with the Young Plan, the occupation of the Rhineland w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armistice Of 11 November 1918
The Armistice of 11 November 1918 was the armistice signed at Le Francport near Compiègne that ended fighting on land, sea, and air in World War I between the Entente and their last remaining opponent, Germany. Previous armistices had been agreed with Bulgaria, the Ottoman Empire and Austria-Hungary. It was concluded after the German government sent a message to American president Woodrow Wilson to negotiate terms on the basis of a recent speech of his and the earlier declared "Fourteen Points", which later became the basis of the German surrender at the Paris Peace Conference, which took place the following year. Also known as the Armistice of Compiègne (french: Armistice de Compiègne, german: Waffenstillstand von Compiègne) from the place where it was officially signed at 5:45 a.m. by the Allied Supreme Commander, French Marshal Ferdinand Foch, it came into force at 11:00 a.m. Central European Time (CET) on 11 November 1918 and marked a vi ...

Western Front (World War I)
The Western Front was one of the main theatres of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The German advance was halted with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918. Between 1915 and 1917 there were several offensives along this front. The attacks employed massive artillery bombardments and massed infantry advances. Entrenchments, machine gun emplacements, barbed wire and artillery repeatedly inflicted severe casualties during attacks and counter-attacks and no significant advances were made. Among the most costly of these offensives were the Battle of Verdun, in 1916, with a combined 700,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Oberkommando Des Heeres
The (; abbreviated OKH) was the Command (military formation), high command of the German Army (1935–1945), Army of Nazi Germany. It was founded in 1935 as part of Adolf Hitler's German rearmament, rearmament of Germany. OKH was ''de facto'' the most important unit within the German war planning until the Battle of Moscow, defeat at Moscow in December 1941. During World War II, OKH had the responsibility of strategic planning of Field army, Armies and Army Groups. The General Staff of the OKH managed operational matters. Each German Army also had an Army High Command ( or AOK). The Armed Forces High Command () then took over this function for theatres other than the Eastern Front (World War II), Eastern front. The OKH commander held the title of Commander-in-chief of the Army (). After the Battle of Moscow, the OKH commander Field marshal Walther von Brauchitsch was removed from office, and Hitler appointed himself as Commander-in-Chief of the Army. From 1938, OKH was, togeth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dogfight
A dogfight, or dog fight, is an aerial battle between fighter aircraft conducted at close range. Dogfighting first occurred in Mexico in 1913, shortly after the invention of the airplane. Until at least 1992, it was a component in every major war, though with steadily declining frequency. Since then, longer-range weapons have made dogfighting largely obsolete. Modern terminology for air-to-air combat is air combat maneuvering (ACM), which refers to tactical situations requiring the use of individual basic fighter maneuvers (BFM) to attack or evade one or more opponents. This differs from aerial warfare, which deals with the strategy involved in planning and executing various missions. Etymology The term ''dogfight'' has been used for centuries to describe a melee: a fierce, fast-paced close quarters battle between two or more opponents. The term gained popularity during World War II, although its origin in air combat can be traced to the latter years of World War I. One of ...

Flanders Fields
Flanders Fields is a common English name of the World War I battlefields in an area straddling the Belgian provinces of West Flanders and East Flanders as well as the French department of Nord-Pas-de-Calais, part of which makes up the area known as French Flanders. Description The name Flanders Fields is particularly associated with battles that took place in the Ypres Salient, including the Second Battle of Ypres and the Battle of Passchendaele. For most of the war, the front line ran continuously from south of Nieuwpoort on the Belgian coast, across Flanders Fields into the centre of Northern France before moving eastwards — and it was known as the Western Front. The phrase was popularized by a poem, "In Flanders Fields", by Canadian Lieutenant-Colonel John McCrae which was inspired by his service during the Second Battle of Ypres.
