SPAD XIII
The SPAD S.XIII is a French biplane fighter aircraft of the First World War, developed by ''Société Pour L'Aviation et ses Dérivés'' (SPAD) from the earlier and highly successful SPAD S.VII. During early 1917, the French designer Louis Béchereau, spurred by the approaching obsolescence of the S.VII, decided to develop two new fighter aircraft, the S.XII and the S.XIII, both using a powerful new geared version of the successful Hispano-Suiza 8A engine. The cannon armament of the S.XII was unpopular, but the S.XIII proved to be one of the most capable fighters of the war, as well as one of the most-produced, with 8,472 built and orders for around 10,000 more cancelled at the Armistice.Sharpe 2000, p. 272. By the end of the First World War, the S.XIII had equipped virtually every fighter squadron of the ''Aéronautique Militaire''. In addition, the United States Army Air Service also procured the type in bulk during the conflict, and some replaced or supplemented S.VIIs in ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Flying Ace
A flying ace, fighter ace or air ace is a military aviation, military aviator credited with shooting down a certain minimum number of enemy aircraft during aerial combat; the exact number of aerial victories required to officially qualify as an ace varies, but is usually considered to be five or more. The concept of the "Ace (military), ace" emerged in 1915 during World War I, at the same time as aerial dogfighting. It was a propaganda term intended to provide the home front with a cult of the hero in what was otherwise a Attrition warfare, war of attrition. The individual actions of aces were widely reported and the image was disseminated of the ace as a chivalrous knight reminiscent of a bygone era. For a brief early period when air-to-air combat was just being invented, the exceptionally skilled pilot could shape the battle in the skies. For most of the war, however, the image of the ace had little to do with the reality of air warfare, in which fighters fought in formation an ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Hispano-Suiza
Hispano-Suiza () is a Spanish automotive company. It was founded in 1904 by Marc Birkigt and as an automobile manufacturer and eventually had several factories in Spain and France that produced luxury cars, aircraft engines, trucks and weapons. In 1923, its French luxury car arm became a semi-autonomous partnership with the Spanish parent company. In 1946, the parent company sold all of its Spanish automotive assets to Enasa, a Spanish state-owned vehicle manufacturer, and the French arm continued as an independent aviation engine and components manufacturer under the Hispano-Suiza name. In 1968, Hispano-Suiza was taken over by the aerospace company Snecma, which is now part of the French Safran, Safran Group. The relaunch of Hispano Suiza Cars has been made by the same founding family (4th generation of the Suqué Mateu Family), the company is part of the Peralada Group (owned as well by the Suqué Mateu family) in 2019 with a fully-electric 1,119 HP hypercar called Hispano-Su ...

Halberstadt D
Halberstadt (; Eastphalian: ''Halverstidde'') is a town in the state of Saxony-Anhalt in central Germany, the capital of Harz district. Located north of the Harz mountain range, it is known for its old town center, which was largely destroyed by Allied bombings in the late stages of World War II after local Nazi leaders refused to surrender. The town was rebuilt in the following decades. In World War I Halberstadt was the site of a German military airbase and aircraft-manufacturing facilities. In World War II Halberstadt was a regional production center for Junkers aircraft, which also housed an SS forced labor camp. Halberstadt now includes the area where the Langenstein-Zwieberge concentration camp was situated. Today the city has around 450 timber framed houses in its city centre and timber framed old villages like Langenstein.
