Euler D.I
The Euler D.I was a German single-seat fighter based on the French Nieuport 17. After seeing the success of the French Nieuport 11 at the front, German designer August Euler August Euler (20 November 1868 – 1 July 1957) was a pioneer German aviator, aircraft constructor and the holder of the first German pilot's license, issued in 1909. After the First World War, he became German Secretary of State for Air, unt ... set about to create a German aircraft based on the Nieuport design. The Euler D.I first flew in late 1916. It was powered by an 80 hp engine with the Euler patented machine gun on the front. Operational history Two prototypes were recorded as being in service at the front in October 1916, and the German government ordered 50 in the same month. A further 50 were ordered in early 1917, but this order was largely transferred over to the D.I's successor, the Euler D.II. The plane saw very little combat service, being largely used as a fighter trainer for the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Euler
August Euler (20 November 1868 – 1 July 1957) was a pioneer German aviator, aircraft constructor and the holder of the first German pilot's license, issued in 1909. After the First World War, he became German Secretary of State for Air, until he retired in 1922. Euler was born at Oelde in Westphalia and was educated at Oelde and at public schools in Cologne and Aachen and from 1885 started a career in engineering. He worked for Seidel & Neumann, originally a sewing machine company, which later made cycles and motor cars. Euler took up cycle racing and then motor racing and became interested in aviation. In 1908 he started a company to build Voisin aircraft under licence. In February 1908 August Euler erected a building on the site of the Griesheim Airport Griesheim Airport is a private airfield in Germany, located southwest of Griesheim (Hessen); approximately southwest of Berlin. Formerly a NATO military airfield, it was closed in 1992. In 1996, a large part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luftstreitkräfte
The ''Deutsche Luftstreitkräfte'' (, German Air Force)—known before October 1916 as (Flyer Troops)—was the air arm of the Imperial German Army. In English-language sources it is usually referred to as the Imperial German Air Service, although that is not a literal translation of either name. German naval aviators of the were an integral part of the Imperial German Navy (). Both military branches operated aeroplanes, observation balloons and airships. Founding The Imperial German Army created an experimental balloon company inspired by the American balloon corps they had seen while observing the American Civil War, with varying forms of organisation from 1884 to 1901 until a Balloon Battalion was finally formed. The rapid development of aeronautics led to trials of airships and the choice of rigid types built by Zeppelin and Schutte-Lanz. The first military aircraft to be acquired by the German Army entered service in 1910 and the first five aviation battalions were es ...

Euler D
Leonhard Euler ( , ; 15 April 170718 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer who founded the studies of graph theory and topology and made pioneering and influential discoveries in many other branches of mathematics such as analytic number theory, complex analysis, and infinitesimal calculus. He introduced much of modern mathematical terminology and notation, including the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory. Euler is held to be one of the greatest mathematicians in history and the greatest of the 18th century. A statement attributed to Pierre-Simon Laplace expresses Euler's influence on mathematics: "Read Euler, read Euler, he is the master of us all." Carl Friedrich Gauss remarked: "The study of Euler's works will remain the best school for the different fields of mathematics, and nothing else can replace it." Euler is a ...

France
France (), officially the French Republic ( ), is a country primarily located in Western Europe. It also comprises of overseas regions and territories in the Americas and the Atlantic, Pacific and Indian Oceans. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and the North Sea; overseas territories include French Guiana in South America, Saint Pierre and Miquelon in the North Atlantic, the French West Indies, and many islands in Oceania and the Indian Ocean. Due to its several coastal territories, France has the largest exclusive economic zone in the world. France borders Belgium, Luxembourg, Germany, Switzerland, Monaco, Italy, Andorra, and Spain in continental Europe, as well as the Netherlands, Suriname, and Brazil in the Americas via its overseas territories in French Guiana and Saint Martin.

Nieuport 17
The Nieuport 17 C.1 (or Nieuport XVII C.1 in contemporary sources) was a French sesquiplane fighter designed and manufactured by the Nieuport company during World War I. An improvement over the Nieuport 11, it was a little larger than earlier Nieuports and better adapted to the more powerful engine than the interim Nieuport 16. Aside from early examples, it had the new Alkan-Hamy synchronization gear, permitting the use of a fuselage-mounted synchronised Vickers gun firing through the propeller disc. At the time of its introduction in March 1916, the type's outstanding manoeuvrability and excellent rate of climb gave it a significant advantage over fighters on both sides and was described as "the best pursuit plane of the day". It was used by many operators and entered service with every Allied power and copies were also operated by the (German Air Service). Mass-produced by several French firms, the Nieuport 17 and its derivatives were built under licence in Italy by Nieupo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1910s German Fighter Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
