The Metropolitan-Vickers F.2 is an early turbojet engine and the first British design to be based on an axial-flow compressor. It was an extremely advanced design for the era, using a nine-stage axial compressor, annular combustor, and a two-stage turbine. It first powered a Gloster Meteor in November 1943, outperforming contemporary models from Power Jets. In spite of this excellent start, it was considered unreliable and never saw use during the war. In the post-war era, a number of engines provided much higher performance, and interest in the F.2 waned. The potential of the engine and the investment did not go to waste, however; the design was passed from Metropolitan-Vickers (MetroVick) to Armstrong Siddeley when MetroVick left the gas turbine business. Armstrong Siddeley produced a larger version as the successful Sapphire. Development Alan Arnold Griffith published a seminal paper in 1926, ''An Aerodynamic Theory of Turbine Design'', that for the first time clearly de ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister 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 outside organization ...
