Renault 90 Hp
The Renault 90 hp, or 12A, was the world’s first V12 engine, V12 aircraft engine. The engine was developed in 1911 from Renault’s earlier V8 engine, V8 engines and used the same Air-cooled engine, air-cooled design. The engine was first exhibited in December 1911 at the Paris Air Show and powered several aircraft during the 1912 competition season. Renault followed up the 90 hp model with a, similarly designed, Renault 100 hp V-12, 100 hp model during the summer of 1912. Design and development By 1911, V12 engines had been built for boats and automobiles however Renault's was the first designed for aircraft use. As with other V12s and Straight-six engine, straight-six engines, Renault's V12 design had the inherent advantage of primary and secondary engine balance. The 60 deg angle between two rows of 6-cylinders resulted in even firing intervals for smooth power delivery and gave the engine a narrower profile than Renault's 90 deg V8s thereby reducing aerodynamic drag.

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".

Spark Plugs
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the ''sid ...

Aéro-Club De France
The Aéro-Club de France () is one of the oldest French aviators' associations still active. It was founded as the Aéro-Club on 20 October 1898 as a society 'to encourage aerial locomotion' by Ernest Archdeacon, Léon Serpollet, Henri de la Valette, Jules Verne and his wife, André Michelin, Albert de Dion, Alberto Santos-Dumont, Henri Deutsch de la Meurthe, and Henry de La Vaulx. On 20 April 1909, its name was changed to ''Aéro-Club de France''. The Aéro-Club de France originally set many of the regulations that controlled aviation in France. From its formation it also set the rules that have marked some of the 'firsts' in aviation, such as the first closed-circuit flight of over 1 km and the first helicopter flight, and has organised competitions including: * the Prix Deutsch de la Meurthe, a challenge for dirigibles from 1901 * the Gordon Bennett Cup for fixed-wing aircraft in 1909 The club published the journal ''L'Aérophile'' from 1898 to 1947, and since ...

Breguet Aviation
The ''Société anonyme des ateliers d'aviation Louis Breguet'' (), also known as Breguet Aviation (), was a French aircraft manufacturer. The company was set up in 1911 by the aviation pioneer Louis Charles Breguet. Breguet Aviation was extremely active during the First World War, producing numerous military aircraft, such as the pioneering metal Breguet 14 day-bomber, for the Allies of World War I, Allies. During the interwar period, the firm's aircraft set several records for non-stop crossings of the Atlantic Ocean, as well as with the unconventional Breguet-Dorand Gyroplane Laboratoire. It was active during the Second World War, surviving the conflict and largely focusing on commercial transport aircraft during the postwar years. Its most notable military programmes during the Cold War include the Breguet 1150 Atlantic and - with British Aircraft Corporation - the SEPECAT Jaguar. During 1971, Breguet Aviation merged with Dassault Aviation, Dassault to form ''Avions Marcel Das ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farman Aviation Works
Farman Aviation Works () was a French aircraft company founded and run by the brothers Richard Farman, Richard, Henri Farman, Henri, and Maurice Farman. They designed and constructed aircraft and engines from 1908 until 1936; during the French nationalization and rationalization of its aeronautical industry, Farman's assets were assigned to the SNCAC, ''Société Nationale de Constructions Aéronautiques du Centre'' (SNCAC). In 1941 the Farman brothers reestablished the firm as the "''Société Anonyme des Usines Farman''" (SAUF), but only three years later it was absorbed by SNCASO, Sud-Ouest. Maurice's son, Marcel Farman, reestablished the SAUF in 1952, but his effort proved unsuccessful and the firm was dissolved in 1956. The Farman brothers designed and built more than 200 types of aircraft between 1908 and 1941. They also built cars until 1931 and boats until 1930. Background In 1907, Henri Farman bought his first aircraft from Gabriel Voisin and soon began to improve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French Franc
The franc (; , ; currency sign, sign: F or Fr), also commonly distinguished as the (FF), was a currency of France. Between 1360 and 1641, it was the name of coins worth 1 livre tournois and it remained in common parlance as a term for this amount of money. It was reintroduced (in French livre, decimal form) in 1795. After two centuries of inflation, it was Redenomination, redenominated in 1960, with each (NF) being worth 100 old francs. The NF designation was continued for a few years before the currency returned to being simply the franc. Many French residents, though, continued to quote prices of especially expensive items in terms of the old franc (equivalent to the new centime), up to and even after the introduction of the euro (for coins and banknotes) in 2002. The French franc was a commonly held international reserve currency of reference in the 19th and 20th centuries. Between 1998 and 2002, the conversion of francs to euros was carried out at a rate of 6.55957 franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
