Boeing X-66A
The Boeing X-66 is an experimental airliner that was under development by Boeing. It is part of the List of X-planes, X-plane series, that was being developed in collaboration with NASA and its Sustainable Flight Demonstrator program. It used an extra-long and thin wing design stabilized by diagonal bracing struts, which is known as a Boeing Truss-Braced Wing, Transonic Truss-Braced Wing. The aircraft configuration was based on research studies referred to as "Subsonic Ultra-Green Aircraft Reach (SUGAR)" which extensively studied truss-bracing and hybrid electric technologies. Development By early 2019, following extensive wind tunnel testing at NASA Ames Research Center, an optimized truss and more wing sweep, sweep for the span wing allowed flying higher and faster, up from Mach number, Mach 0.70–0.75 to Mach 0.80 like current jetliners. Compared to aircraft with cantilevered wings, fuel burn will be reduced by 8-10%, and the technology should be ready by 2030-2035. Aspect ...

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] |
