Walter Atlas
The Walter Atlas was a nine-cylinder, air-cooled, radial engine for aircraft use built in Czechoslovakia in the early 1930s. Design and development The Atlas was the largest capacity and most powerful radial engine design developed by the Walter company. The engine was an attempt at high power output by using a much larger bore size than company's previous range. The engine was test run in spring 1930, encountering problems with cooling and operation.Němeček 1983. The engine appeared at the Paris Aerosalon in December of that year. The engine did not attract any customers, further development was cancelled in 1931 and the company moved to producing licensed versions of the Bristol Mercury, Pegasus and Gnome-Rhône 14M. Variants ;Atlas I :Direct drive, maximum power at 1,950 rpm. ;Atlas IR : Geared drive (ratio 1: 1.625), maximum power hp at 1,950 rpm. Weight increased to .

Gnome-Rhône 14M
The Gnome-Rhône 14M was a small 14-cylinder two-row air-cooled radial engine that was used on several French and German aircraft of World War II. While having the same appearance, number of pistons (14) and two-row layout typical of Gnome-Rhône radial engines, the 14M was built to a smaller frame intended to power a lighter class of aircraft. It was designed with lower displacement and power, smaller in size and with less weight compared to the larger, heavier Gnome-Rhône 14N and its well-known predecessor.

Walter Aircraft Engines
Walter Aircraft Engines is an aircraft engine manufacturer and former automotive manufacturer. Its notable products include the M601 turboprop. The company is based in Prague, Czech Republic. It has been a subsidiary of GE Aviation since July 2008. History Josef Walter founded the company in 1911 to make motorcycles and motor tricycles. It started to make automobiles in 1913: initially its own models, and later the Fiat 508, 514, 522 and 524 under licence. By 1926 Walter was Czechoslovakia's fourth-largest car maker by sales volume. In 1929 it still held fourth place, and production peaked at 1,498 cars for the year. By 1932 Walter production had slumped to 217 cars for the year. The figure recovered to 474 in 1933, but fell again to 102 in 1936 and to only 13 in 1937. Walter ceased car production in 1954. From the early 1920s Walter also manufactured BMW aircraft engines under license, as well as its own family of air-cooled radial piston engines. In the 1930s Walter als ...

Benzene
Benzene is an organic chemical compound with the molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Benzene is a natural constituent of petroleum and is one of the elementary petrochemicals. Due to the cyclic continuous pi bonds between the carbon atoms, benzene is classed as an aromatic hydrocarbon. Benzene is a colorless and highly flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline. It is used primarily as a precursor to the manufacture of chemicals with more complex structure, such as ethylbenzene and cumene, of which billions of kilograms are produced annually. Although benzene is a major industrial chemical, it finds limited use in consumer items because of its toxicity. History Discovery The word "''benzene''" derives from "''gum benzoin''" (benzoin res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenith Carburetor Company
Zenith Carburetor (later the Fuel Devices Division of Bendix Corporation) was an American manufacturer of gasoline engine management systems and components, chiefly carburetors and filters. It was founded in Detroit, Michigan in 1911 as a subsidiary of the French . Carburetors in most cases were replaced by fuel injection systems, also provided by Bendix, during the 1970s. Anthony Messina The design of the Zenith was perfected around 1889-1903 by Anthony Messina of Rhinelander, Wisconsin. The carburetor had two jets, one for rich mixture, one for lean. The mixture was then combined in the right proportions for the engine's speed and load. The Zenith design won first prize in a competition with 14 others organized by the Royal Prussian War Ministry in 1903. Ford Zenith's product was one of a small number of different carburetors used on the Ford Model T. It was also fitted to most of the 4.8 million Ford Model A cars built from 1927 to 1931 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Propeller Speed Reduction Unit
A propeller speed reduction unit is a gearbox or a belt and pulley device used to reduce the output revolutions per minute (rpm) from the higher input rpm of the powerplant.Gunston 2006, p. 82. This allows the use of small displacement internal combustion engines to turn aircraft propellers within an efficient speed range. History and operation The Wright brothers recognised the need for propeller reduction gearing in 1903, but it was not generally used on aircraft engines until larger engines were designed in the 1920s. Large engines with high crankshaft speeds and power outputs demanded propeller reduction, pilots noted the increase in performance of similar aircraft fitted with reduction gearing. Types Types of propeller speed reduction units include: *Chain drive *Single reduction or spur gear *Internal spur gear *Farman or bevel planetary type *Fixed sun gear *Fixed internal gear *Belt drive *Epicyclic gearing Design variations The Rolls-Royce Falcon engine of 1915 fea ...

Bristol Pegasus
The Bristol Pegasus is a British nine-cylinder, single-row, air-cooled radial aero engine. Designed by Roy Fedden of the Bristol Aeroplane Company, it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Mercury and Jupiter engines, later variants could produce 1,000 horsepower (750 kW) from its capacity of 1,750 cubic inches (28 L) by use of a geared supercharger. Further developments of the Pegasus created the fuel-injected Bristol Draco and the diesel cycle Bristol Phoenix, both types being produced in limited numbers. In contrast, by the end of production over 30,000 Pegasus engines had been built. Aircraft applications ranged from single-engine biplanes to the four-engined Short Sandringham and Sunderland flying boats. Several altitude and distance records were set by aircraft using the Pegasus. The Bristol Siddeley company reused the name many years later for the turbofan engine used in the Hawker Siddeley Harrier a ...

Bristol Mercury
The Bristol Mercury is a British nine-cylinder, air-cooled, single-row, piston radial engine. Designed by Roy Fedden of the Bristol Aeroplane Company it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Jupiter engine, later variants could produce 800 horsepower (600 kW) from its capacity of 1,500 cubic inches (25 L) by use of a geared supercharger. Almost 21,000 engines were produced, with a number also being built under license elsewhere in Europe. Several examples remain airworthy, with other preserved examples on public display in aviation museums. Design and development The Mercury was developed by the Bristol Aeroplane Company in 1925 as their Bristol Jupiter was reaching the end of its lifespan. Although the Mercury initially failed to attract much interest, the Air Ministry eventually funded three prototypes and it became another winner for the designer Roy Fedden.
