Hanriot HD.1
The Hanriot HD.1 was a French World War I single-seat fighter aircraft. Rejected for service with French squadrons in favour of the SPAD S.VII, the type was supplied to the Belgian Army′s (Belgian Military Aviation) and the (Military Aviation Corps) of the Royal Italian Army, with both of which it proved highly successful. Of a total of about 1,200 examples built, 831 were produced by Italian companies under licence. Development and production The Hanriot company produced a series of pioneering monoplanes pre-war but had settled down as a licence manufacturer, notably of Sopwith 1½ strutters, when the HD.1 was produced in 1916. The type was a conventional fighter with the general characteristics of a typical Sopwith aircraft, being strongly but lightly built and combining clean lines with a light wing loading. It used the same "1½" (or "W") cabane strut arrangement as the Sopwith two-seater. It had a flat lower wing, though the top wing had quite sharp dihedral.Cheesman ...

Wing Loading
In aerodynamics, wing loading is the total mass of an aircraft or flying animal divided by the area of its wing. The stalling speed of an aircraft in straight, level flight is partly determined by its wing loading. An aircraft or animal with a low wing loading has a larger wing area relative to its mass, as compared to one with a high wing loading. The faster an aircraft flies, the more lift can be produced by each unit of wing area, so a smaller wing can carry the same mass in level flight. Consequently, faster aircraft generally have higher wing loadings than slower aircraft. This increased wing loading also increases takeoff and landing distances. A higher wing loading also decreases maneuverability. The same constraints apply to winged biological organisms. Range of wing loadings Effect on performance Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Ace
A flying ace, fighter ace or air ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat. The exact number of aerial victories required to officially qualify as an ace is varied, but is usually considered to be five or more. The concept of the "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 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 and air superiority depended heavily on the relative availability ...

Willy Coppens
Willy Omer François Jean baron Coppens de Houthulst (6 July 1892 – 21 December 1986) was Belgium's leading fighter ace and the champion "balloon buster" of World War I. He was credited with 37 confirmed victories and six probables. Early life Coppens was born in Watermael-Boitsfort, son of Omer Coppens, a Belgian impressionistic painter who studied in the Royal Academy of Ghent. He was conscripted into the army in 1912, to serve with the ''Premiere Regiment Grenadiers''. World War I In 1914, following the German invasion of Belgium, Coppens transferred to The Motor Machine Gun Corps. On 6 September 1915, he signed up for flight training in the Compagnie des Aviateurs. Ultimately, due to insufficiencies in Belgian training, he took eight weeks of leave to train to fly. He and 39 other Belgians learned to fly on their own expense in Britain. He received his pilot's certificate on 9 December 1915. After this training in Britain he had further training at the Farman Scho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seaplane
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplan ...

French Navy
The French Navy (french: Marine nationale, lit=National Navy), informally , is the maritime arm of the French Armed Forces and one of the five military service branches of France. It is among the largest and most powerful naval forces in the world, ranking seventh in combined fleet tonnage and fifth in number of naval vessels. The French Navy is one of eight naval forces currently operating fixed-wing aircraft carriers,Along with the U.S., U.K., China, Russia, Italy, India and Spain with its flagship being the only nuclear-powered aircraft carrier outside the United States Navy, and one of two non-American vessels to use catapults to launch aircraft. Founded in the 17th century, the French Navy is one of the oldest navies still in continual service, with precursors dating back to the Middle Ages. It has taken part in key events in French history, including the Napoleonic Wars and both world wars, and played a critical role in establishing and securing the French colonial ...

Nieuport 17
The Nieuport 17 C.1 (or Nieuport XVII C.1 in contemporary sources) was a French sesquiplane fighter designed and manufactured by the Nieuport company during World War I. An improvement over the Nieuport 11, it was a little larger than earlier Nieuports and better adapted to the more powerful engine than the interim Nieuport 16. Aside from early examples, it had the new Alkan-Hamy synchronization gear, permitting the use of a fuselage-mounted synchronised Vickers gun firing through the propeller disc. At the time of its introduction in March 1916, the type's outstanding manoeuvrability and excellent rate of climb gave it a significant advantage over fighters on both sides and was described as "the best pursuit plane of the day". It was used by many operators and entered service with every Allied power and copies were also operated by the (German Air Service). Mass-produced by several French firms, the Nieuport 17 and its derivatives were built under licence in Italy by Nieupo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vigna Di Valle 20110812 — Macchi Hanriot HD
''Vigna'' is a genus of plants in the legume family, Fabaceae, with a pantropical distribution.Aitawade, M. M., et al. (2012)Section ''Ceratotropis'' of subgenus ''Ceratotropis'' of ''Vigna'' (Leguminosae–Papilionoideae) in India with a new species from northern Western Ghats. ''Rheedea'' 22(1), 20-27. It includes some well-known cultivated species, including many types of beans. Some are former members of the genus ''Phaseolus''. According to ''Hortus Third'', ''Vigna'' differs from ''Phaseolus'' in biochemistry and pollen structure, and in details of the style and stipules. ''Vigna'' is also commonly confused with the genus '' Dolichos'', but the two differ in stigma structure. ''Vigna'' are herbs or occasionally subshrubs. The leaves are pinnate, divided into 3 leaflets. The inflorescence is a raceme of yellow, blue, or purple pea flowers. The fruit is a legume pod of varying shape containing seeds.

Macchi
Aermacchi was an Italian aircraft manufacturer. Formerly known as Aeronautica Macchi, the company was founded in 1912 by Giulio Macchi at Varese in north-western Lombardy as Nieuport-Macchi, to build Nieuport monoplanes under licence for the Italian military. With a factory located on the shores of Lake Varese, the firm originally manufactured a series of Nieuport designs, as well as seaplanes. After World War II, the company began producing motorcycles as a way to fill the post-war need for cheap, efficient transportation. The company later specialised in civil and military pilot training aircraft. In July 2003, Aermacchi was integrated into the Finmeccanica Group (now Leonardo) as Alenia Aermacchi, which increased its shareholding to 99%. Military trainers Since the beginning, the design and production of military trainers have been the core business of Alenia Aermacchi. The products include: * SF-260, piston-engined or turboprop-powered screener/primary trainer * MB- ... [...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 ...

Synchronization Gear
A synchronization gear (also known as a gun synchronizer or interrupter gear) was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target. There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two had to operate. In practice, all known gears worked on the principle of actively triggering each shot, in the manner of a semi-automatic weapon. Design and experimentation with gun synchronization had been underway in France and Germany in 1913–1914, following the ideas of August Euler, who seems to have been the first to suggest mounting a fixed armament firing in the direction of flight (in 191 ...

Rotary Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional ra ...
