Hanriot HD.12
The Hanriot HD.2 was a biplane floatplane fighter aircraft produced in France during the First World War that was used after the war for testing the use of aircraft from warships. Development The design was based on that of the HD.1, but was a purpose-built floatplane. It had larger tail surfaces and a shorter wingspan with greater area. Like its predecessor, though, it was a conventional single-bay biplane with staggered wings of unequal span. The prototype had a twin pontoon undercarriage, with a small third pontoon under the tail. The third pontoon was later discarded on production machines, though. Operational history The HD.2 was developed specifically as an interceptor to defend flying boat bases, but soon was used as an escort fighter to protect French reconnaissance flying boats. The United States Navy also bought 10 examples with wheeled undercarriages, designated HD.2C. Both the French and United States navies used these aircraft in early experiments in launching f ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister 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'' 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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Hispano-Suiza 8Ac
The Hispano-Suiza 8 was a water-cooled V8 SOHC aero engine introduced by Hispano-Suiza in 1914, and was the most commonly used liquid-cooled engine in the aircraft of the Entente Powers during the First World War. The original Hispano-Suiza 8A was rated at and the later, larger displacement Hispano-Suiza 8F reached . Hispano-Suiza 8 engines and variants produced by Hispano-Suiza and other companies under licence were built in twenty-one factories in Spain, France, Britain, Italy, and the U.S. Derivatives of the engine were also used abroad to power numerous aircraft types and the engine can be considered as the ancestor of another successful engine by the same designer, the Hispano-Suiza 12Y (and Soviet Klimov V12 derivative aero-engines) which was in service during the Second World War. Design and development Origins At the beginning of World War I, the production lines of the Barcelona based Hispano-Suiza automobile and engine company were switched to the production of war ...

Biplanes
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 o ...

Floatplanes
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1910s French 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.

Hanriot Aircraft
Aéroplanes Hanriot et Cie. or simply 'Hanriot' was a French aircraft manufacturer with roots going back to the beginning of aviation. Founded by René Hanriot in 1910 as ''The Monoplans Hanriot Company Ltd.'' the company survived in different forms until 1916 when it established itself with the Hanriot-Dupont (HD.) fighters and observation aircraft. The company lasted through several takeovers and structural changes until in 1936 it merged with Farman to become the Société Nationale de Constructions Aéronautiques du Centre (SNCAC). 'Central Air Works' consortium. Hanriot aeroplanes included pre-war monoplanes with boat-like fuselages, the HD.1 and 2 World War I biplane fighters, the HD.14 trainer, and the H.220 series of twin-engined heavy fighters that eventually evolved in the SNCAC 600 fighter just before World War II. The company's main bases of operations were Bétheny (a suburb of Reims) Boulogne-Billancourt, Carrières-sur-Seine and Bourges. History René Hanriot ...

Sopwith Baby
The Sopwith Baby is a British single-seat floatplane that was operated by the Royal Naval Air Service (RNAS) from 1915. Development and design The Baby (also known as the Admiralty 8200 Type) was a development of the two-seat Sopwith Schneider. The Baby utilized a wooden structure with fabric covering. A Lewis Gun was fitted, either above the fuselage firing through the propeller arc without the benefit of synchronization, or over the top wing, firing above it. To meet the more demanding conditions of 1916–18, Further modifications were made on aircraft built by Blackburn Aircraft at Leeds, United Kingdom. A modified variant of the Baby, the Fairey Hamble Baby was built by Fairey and Parnall. The Royal Naval Air Service ordered 286 Sopwith Babies of which 100 were built by Sopwith at Kingston and 186 by Blackburn Aircraft at Leeds with others for export. License manufacture was also undertaken in Italy by SA Aeronautica Gio Ansaldo of Turin, who built 100 examples for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers Machine Gun
The Vickers machine gun or Vickers gun is a Water cooling, water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allies of World War I, Allied World War I fighter aircraft. The weapon had a reputation for great solidity and reliability. Ian V. Hogg, in ''Weapons & War Machines'', describes an action that took place in August 1916, during which the British 100th Company of the Machine Gun Corps fired their ten Vickers guns to deliver sustained fire for twelve hours. Using 100 barrels, they fired a million rounds without breakdowns. "It was this absolute foolproof reliability which endeared the Vickers to every Britis ...
