Schütte-Lanz D.I
The Schütte-Lanz D.I was a German single-seat biplane fighter, often said to be Germany's first biplane attack aircraft. The D.I was light-weight and made of wood covered in fabric, apparently based on the British design of the Sopwith Tabloid. Operational history After Idflieg testing in 1915, the plane was rejected on the grounds that the biplane design afforded less vision to the pilot than a monoplane and was as such unsuitable for use as a fighter. A modified version, the Schütte-Lanz D.II The Schütte-Lanz D.II was a variant of the Schütte-Lanz D.I. The only change was a new engine - the 100 hp Mercedes D.I 6-cylinder water-cooled engine replacing the 80 hp Oberursel U.0 Oberursel (Taunus) () is a town in Germany and ... was produced in the same year.

Walter Stein
Walter Johannes Stein (6 February 1891, in Vienna – 7 July 1957, in London) was an Austrian philosopher, Waldorf school teacher, Grail researcher, and one of the pioneers of anthroposophy. Biography Of Jewish descent, Stein studied mathematics, physics, and philosophy at Vienna University, before completing a doctorate in philosophy at the end of the First World War, having continued work on it throughout his service in an artillery unit in the war. He became a personal student of Rudolf Steiner from about the age of 21, and enjoyed the unofficial supervision of Steiner while writing his dissertation. Broadly speaking, the dissertation was an attempt to write a theory of cognition for spiritual knowledge. After the First World War, Stein assisted Steiner in promoting Social Threefolding. When it became apparent in 1919 that these efforts were not going to succeed, Steiner asked Stein to teach history and German literature at the first Waldorf School in Stuttgart. It was as p ...

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 est ...

Sopwith Tabloid
The Sopwith Tabloid and Sopwith Schneider (floatplane) were British biplanes, originally designed as sports aircraft and later adapted for military use. They were among the first successful types to be built by the Sopwith Aviation Company. The " Tabloid", so named because of its small size, caused a sensation when it made its first public appearance. A floatplane variant was prepared in under a month and entered for the 1914 Schneider Trophy race where it was piloted by Howard Pixton. This aircraft won the competition against minimal opposition.Bruce, 1996, p.1 Production orders for both types were placed by the military, and although a few Gnome Lambda-powered Tabloids saw limited service in the early war years, some Schneiders were still in Naval service four years later, at the end of the First World War. Design and development The original Tabloid, which was first flown by Harry Hawker on 27 November 1913, was a two-seat single-bay biplane with a side-by-side seating, whi ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

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. Events By place Parthia * King Vologases IV of Parthia dies after a 44-year reign, and is succeeded by his son Vologases V.
