E.N.V. Motor Syndicate
E.N.V. was an early manufacturer of aircraft engines, originally called the London and Parisian Motor Company, their first model appearing in 1908. E.N.V. engines were used by several pioneer aircraft builders and were produced in both France and the UK until about 1914. They subsequently specialised in camshafts and bevel gear manufacture until 1968 when the name was lost. The company The London and Parisian Motor Co. was an Anglo-French venture registered in London in 1908 and largely backed with British capital and expertise. The castings and forgings for its engines were made in Sheffield where the company was originally based, then taken to France for assembly. The reason for this was that there was much more aeronautical activity in France than in England in 1908, but the French were taxing imported machinery. The French works were in Courbevoie in the Paris suburbs. By 1909 there was more aviation activity in England and E.N.V. decided to begin full manufacture at h ...

Sheffield
Sheffield is a city in South Yorkshire, England, situated south of Leeds and east of Manchester. The city is the administrative centre of the City of Sheffield. It is historically part of the West Riding of Yorkshire and some of its southern suburbs were transferred from Derbyshire to the city council. It is the largest settlement in South Yorkshire and the third largest of Northern England. The city is in the North Midlands, in the eastern foothills of the Pennines and the valleys of the River Don with its four tributaries: the Loxley, the Porter Brook, the Rivelin and the Sheaf. Sixty-one per cent of Sheffield's entire area is green space and a third of the city lies within the Peak District national park and is the fifth-largest city in England. There are more than 250 parks, woodlands and gardens in the city, which is estimated to contain around 4.5 million trees. Sheffield played a crucial role in the Industrial Revolution, developing many signifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre De Caters
Baron Pierre de Caters (25 December 1875, in Berchem – 21 March 1944, in Paris) was a Belgian adventurer, aviator and car and motorboat racer. In 1908, he was the first Belgian to fly an aircraft. He was also the first Belgian to receive a pilot's license from the Belgian air club on 2 December 1909 and received a gold medal for the first kilometer in the same year. He was the first aircraft manufacturer in Belgium and the first instructor of military aviation. He also took part in car and motorboat races in Belgium and France. In 1904, he briefly held the land speed record, driving a DMG Mercedes Simplex at on a beach course in Ostend, Belgium. In World War I he joined Belgian military aviation, commanding the flying school of Étampes. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting took place mainly in European theatre of World War I, Europe and the Middle Eastern theatre of World War I, Middle East, as well as in parts of African theatre of World War I, Africa and the Asian and Pacific theatre of World War I, Asia-Pacific, and in Europe was characterised by trench warfare; the widespread use of Artillery of World War I, artillery, machine guns, and Chemical weapons in World War I, chemical weapons (gas); and the introductions of Tanks in World War I, tanks and Aviation in World War I, aircraft. World War I was one of the List of wars by death toll, deadliest conflicts in history, resulting in an estimated World War I casualties, 10 million military dead and more than 20 million wounded, plus some 10 million civilian de ...

Airship
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying powered aircraft, under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift (physics), lift needed to stay airborne. In early dirigibles, the lifting gas used was hydrogen gas, hydrogen, due to its high lifting capacity and ready availability, but the inherent flammability led to several fatal accidents that rendered hydrogen airships obsolete. The alternative lifting gas, helium gas is not flammable, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airship usage in North America. Most airships built since the 1960s have used helium, though some have used thermal airship, hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gnome Et Rhône
Gnome et Rhône was a major French aircraft engine manufacturer. Between 1914 and 1918 they produced 25,000 of their 9-cylinder Delta and Le Rhône 110 hp (81 kW) rotary designs, while another 75,000 were produced by various licensees. These engines powered the majority of aircraft in the first half of the war, both Allied designs as well as German examples produced by Motorenfabrik Oberursel. In the post-war era they started a new design series originally based on the Bristol Jupiter, but evolving into the excellent twin-row, 1,000 hp-class (750 kW) Gnome-Rhône 14K ''Mistral Major'' radial, which was likewise licensed and used around the world during World War II. They were a major supplier of engines to the German ''Luftwaffe'', producing both their own designs as well as German ones under licence. Their factories were the target of highly accurate bombing, knocking them out of the war. The company was nationalized as a part of Snecma in 1945, but the ...

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 radi ...

Anzani
Anzani was an engine manufacturer founded by the Italian Alessandro Anzani (1877–1956), which produced proprietary engines for aircraft, cars, boats, and motorcycles in factories in Britain, France and Italy. Overview From his native Italy, Anzani moved to France where he became involved in cycle racing. He moved on to motorcycles and designed and built a record-breaking lightweight engine. In 1907, he set up a small workshop in Paris with three staff and while they were building his engines, he designed a hydrofoil powered by one of his engines and propellers. Aircraft engines He supplied one of his engines to Enrico Forlanini and developed it further into a three-cylinder, air-cooled, radial engine ideal for the new aeroplanes. One of the early engines, the 25 hp Anzani W-3 or Fan type, was supplied to Louis Blériot who used it on his successful first aircraft crossing of the English Channel in 1909. Types * Anzani 3-cyl. Fan 10-12 hp 3.35" × 3.35" * Anzani 3-cyl. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps. Air-cooled engines are widely seen in applications where weight or simplicity is the primary goal. Their simplicity makes them suited for uses in small applications like chainsaws and lawn mowers, as well as small generators and similar roles. These qualities also make them highly suitable for aviation use, where they are widely used in general aviation aircraft and as auxiliary power units on larger aircraft. Their simplicity, in particular, also makes them common on motorcycles. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head. A fl ...

Antoinette (manufacturer)
Antoinette was a French manufacturer of light petrol engines. Antoinette also became a pioneer-era builder of aeroplanes before World War I, most notably the record-breaking monoplanes flown by Hubert Latham and René Labouchère. Based in Puteaux, the Antoinette concern was in operation between 1903 and 1912. The company operated a flying school at Chalons for which it built one of the earliest flight simulators. Private engine-building venture Antoinette began as a private venture led by the engineer Léon Levavasseur and financed by Jules Gastambide, who owned an electricity generating station in Algeria. While on holiday with Gastambide and his family in 1902, Levavasseur expressed his interest in the emerging field of aviation and proposed the development of light, powerful engines for use in aircraft. Levavasseur then suggested to Gastambide's daughter, Antoinette, that the engines should be named after her. Gastambide financed the venture. Levavasseur patented t ...

Farman
Farman Aviation Works () was a French aircraft company founded and run by the brothers Richard, 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 ''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 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 the design of the aircraft; as a result ...
