Sunbeam Arab
The Sunbeam Arab was a British First World War-era aircraft engine, aero engine. Design and development By 1916 the demand for aero-engines was placing huge demands on manufacturing. To help ease the pressure, the War Office standardised on engines of about ; one of these was a V8, V-8 Water cooling (engines), water-cooled engine from Sunbeam known as the Arab. Using cast aluminium alloy cylinder blocks and heads with die-cast aluminium alloy pistons, the Arab had a bore of and stroke of for a capacity of , developing at 2,000 rpm. First bench-run in 1916, the Arab was obviously inspired by the Hispano-Suiza V-8 engines but with very little in common when examined in detail. After submission to the Internal Combustion Engine Committee of the Advisory Committee on Aeronautics Sunbeam received an order for 1,000 in March 1917. The order formed part of the strategy of Sir William Weir to bypass the skilled engineering workforce needed to build Rolls-Royce Eagle and Rolls-Royce ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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 outsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
