Hispano-Suiza 8
The Hispano-Suiza 8 is a Internal combustion engine cooling, water-cooled V8 engine, V8 SOHC aero engine introduced by Hispano-Suiza in 1914 that went on to become 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.

Dual Ignition
Dual Ignition is a system for spark-ignition engines, whereby critical ignition components, such as spark plugs and magnetos, are duplicated. Dual ignition is most commonly employed on aero engines,Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 177. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', (27th revised edition), page 67, and is sometimes found on cars and motorcycles. Dual ignition provides two advantages: redundancy in the event of in-flight failure of one ignition system; and more efficient burning of the fuel-air mixture within the combustion chamber. In aircraft and gasoline-powered fire fighting equipment, redundancy is the prime consideration, but in other vehicles the main targets are efficient combustion and meeting emission law requirements. Efficiency A dual ignition system will typically provide that each cylinder has twin spark plugs, and that the engine will have at least two ignition c ...

Wright Company
The Wright Company was the commercial aviation business venture of the Wright brothers, established by them on November 22, 1909, in conjunction with several prominent industrialists from New York and Detroit with the intention of capitalizing on their invention of the practical airplane. The company maintained its headquarters office in New York City and built its factory in Dayton, Ohio. History The two buildings designed by Dayton architect William Earl Russ and built by Rouzer Construction for the Wright Company in Dayton in 1910 and 1911 were the first in the United States constructed specifically for an airplane factory and were included within the boundary of Dayton Aviation Heritage National Historical Park in 2009. The Wright Company concentrated its efforts on protecting the company's patent rights rather than on developing new aircraft or aircraft components, believing that innovations would hurt the company's efforts to obtain royalties from competing manufacturers ...

Peugeot 8Aa
The Peugeot 8Aa, or L112, is a water-cooled V8 engine, V8 aircraft engine that equipped the Voisin VIII Bomber, bombers and Escort fighter, escort fighters built during World War I. The engine was designed to meet a 1915 request from the French armament ministry for aero engines capable of long endurance at high altitudes. Peugeot responded to the ministry’s request with a design based on their successful Auto racing, racing car engines. Orders were placed for 250 engines in late 1915 even though the first engine did not complete its 50-hour acceptance test until February 1916. For an engine of its time period, the Peugeot 8Aa engine has many innovative features, including Overhead camshaft engine#Double overhead camshaft (DOHC), double overhead camshafts, four valves per cylinder and a dry sump. The engine was noted for having exceptional fuel efficiency, but suffered from poor mechanical reliability. Frequent engine failures lead to the decision, taken in May 1917, to with ...

Brasier
Brasier was a French automobile manufacturer, based in the Paris conurbation, and active between 1905 and 1930. The firm began as Richard-Brasier in 1902, and became known as Chaigneau-Brasier in 1926. __TOC__ Origins Charles-Henri Brasier worked briefly with Panhard and then for some years with Émile Mors before, at the age of 35, he set himself up as an automobile manufacturer on his own account. He did this in partnership with Georges Richard, the two of them establishing the Richard-Brasier business in 1902. By 1905, relations had broken down between the partners due to Richard being frequently away from his desk due to his motor racing activities and, it was reported, injuries he sustained as a result. The strained relations prompted Richard to leave the company that year to found Unic. The newly renamed Brasier firm was therefore born into an atmosphere of recrimination and litigation. Nevertheless, Brasier retained the premises originally acquired by the Richard- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ariès
The Ariès was a French automobile manufactured by La Société des Automobile Ariès in Asnières-sur-Seine. The firm was founded in 1902 by Baron . The decision to end production was taken in 1937. Around 20,000 vehicles were produced in total. The first cars were two-cylinder (engine), two- and four-cylinder vehicles built 20 chassis at a time in a large factory. These shaft-drive cars had a rather unusual double rear axle, while the engines were built by Aster (auto parts company), Aster. In 1907 the company made its own narrow-angle V4 engine. The engine had a single cast iron monobloc head, monobloc on a light alloy crankcase. This contained four cylinders in a square layout with a narrow 15° vee angle. Bore and stroke were 60 by 100mm, giving a capacity of 1.13 litres. It was rated at 8/10 fiscal horsepower.

Air Superiority
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPAD VII
The SPAD S.VII C.1 was the first in a series of single-seat biplane fighter aircraft produced by ''Société Pour L'Aviation et ses Dérivés'' (SPAD) during the First World War. Like its successors, the S.VII was renowned as a sturdy and rugged aircraft with good diving characteristics. It was also a stable gun platform, although pilots used to the more manoeuvrable Nieuport fighters found it heavy on the controls. It was flown by a number of famous aces, such as France's Georges Guynemer, Italy's Francesco Baracca and Australia's Alexander Pentland. Design and development Origins In February 1915, Swiss designer Marc Birkigt had created an overhead cam aviation powerplant based on his Hispano-Suiza V8 automobile engine, resulting in a engine capable of producing at 1,400 rpm. Further refinement brought the power to by July 1915. Given the engine's potential, French officials ordered called upon aircraft designers to create a new high-performance fighter around th ...
