Tupolev Tu-244
The Tupolev Tu-244 was a proposed supersonic transport (SST) aircraft, developed from the Tu-144. It implemented novel features such as cryogenic fuel to enable flight distances of up to and would have carried up to 300 passengers. The project was cancelled in 1993. History The draft work began in 1979, and when the project ended in 1993 substantial progress had already been made during the interpretation. Specifically, the air resistance in the range of Mach 2 was only 50% higher than a conventional passenger airliner traveling at a speed of Mach 0,9. The nearly-circular fuselage ( width, height) and the wing unit would have consisted to a large extent of titanium-composite materials. The engines were to be higher performance hydrogen-fuelled versions of the Kuznetsov NK-321 turbofan, used also with the Tu-160. Adjustable air intake ramps from the Tu-160 might have been included. Projected passenger capacity was 311. Fly-by-wire Fly-by-wire (FBW) is a system that repl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
