Fokker D.VI
The Fokker D.VI was a German fighter aircraft built in limited numbers at the end of World War I. The D.VI served in the German and Austro-Hungarian air services. Design and development In late 1917, Fokker-Flugzeugwerke built two small biplane prototypes designated V.13. These aircraft combined a set of scaled-down D.VII wings with a fuselage and empennage closely mirroring those of the earlier Dr.I.Gray and Thetford 1962, p. 103. The first prototype utilized an 82 kW (110 hp) Oberursel Ur.II rotary engine, while the second featured a 119 kW (160 hp) Siemens-Halske Sh.III bi-rotary engine.Weyl 1965, p. 262. Fokker submitted both prototypes at the Adlershof fighter trials in late January 1918.Weyl 1965, p. 264. At that time, Fokker reengined the first prototype with the 108 kW (145 hp) Oberursel Ur.III.Weyl 1965, p. 264. Pilots found the V.13s to be maneuverable and easy to fly.Weyl 1965, p. 269.

Maschinengewehr 08
The ''Maschinengewehr'' 08, or MG 08, was the German Army's standard machine gun in World War I and is an adaptation of Hiram S. Maxim's original 1884 Maxim gun. It was produced in a number of variants during the war. The MG 08 served during World War II as a heavy machine gun in many German infantry divisions, although by the end of the war it had mostly been relegated to second-rate fortress units. The ''Maschinengewehr'' 08 (or MG 08)—so-named after 1908, its year of adoption—was a development of the license made ''Maschinengewehr'' 01. The firing rate depends on the lock assembly used and averages 500 rounds per minute for the Schloss 08 and 600 rounds per minute for the Schloss 16. The gun used 250-round fabric belts of 7.92×57mm ammunition. It was water-cooled, using a jacket around the barrel that held approximately of water. Using a separate attachment sight with range calculator for indirect fire, the MG 08 could be operated from cover. Additional telescopic sig ...

Royal Hungarian Air Force
The Hungarian Air Force ( hu, Magyar Légierő), is the air force branch of the Hungarian Defence Forces. The task of the current Hungarian Air Force is primarily defensive purposes. The flying units of the air force are organised into a single command; under the Air Command and Control Centre.

This air arm became the Hungarian Red Air Force under the short-lived Hungarian Soviet Republic, but was disbanded upon its downfall.

Armistice With Germany (Compiègne)
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.

Ersatz
An ersatz good () is a substitute good, especially one that is considered inferior to the good it replaces. It has particular connotations of wartime usage. Etymology ''Ersatz'' is a German word literally meaning ''substitute'' or ''replacement''. Although it is used as an adjective in English, it is a noun in German. In German orthography noun phrases formed are usually represented as a single word, forming compound nouns such as ''Ersatzteile'' ("spare parts") or ''Ersatzspieler'' ("substitute player"). While ''ersatz'' in English generally means that the substitution is of unsatisfactory or inferior quality compared with the "real thing", in German, there is no such implication: e.g., ''Ersatzteile'' 'spare parts' is a technical expression without any implication about quality, whereas ''Kaffeeersatz'' ' coffee substitute' is not made from coffee beans, and is thus inferior. The term for inferior substitute in German would be ''Surrogat'', which is cognate to English word " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castor Oil
Castor oil is a vegetable oil pressed from castor beans. It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is and its density is 0.961 g/cm3. It includes a mixture of triglycerides in which about 90% of fatty acids are ricinoleates. Oleic acid and linoleic acid are the other significant components. Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold-resistant plastics, waxes and polishes, nylon, and perfumes. Etymology The name probably comes from a confusion between the '' Ricinus'' plant that produces it and another plant, the '' Vitex agnus-castus''. An alternative etymology, though, suggests that it was used as a replacement for castoreum. Composition Castor oil is well known as a source of ricinoleic acid, a monounsaturated, 18-carbon fatty acid. Among fatty acids, ricinoleic acid is unusual in that it has a hydroxyl functiona ...
