Comac Arj21
The Comac C909, originally known as the ARJ21 Xiangfeng (), is a 78–90 seat regional jet manufactured by the Chinese state-owned aerospace company Comac. Development of the ARJ21 began in March 2002, led by the state-owned ACAC consortium. The first prototype was rolled out on 21 December 2007, and made its maiden flight on 28 November 2008 from Shanghai. It received its CAAC Type Certification on 30 December 2014 and was introduced on 28 June 2016 by Chengdu Airlines. The ACAC consortium was reorganized in 2009 as part of Comac and the jet was rebranded as the C909 in November 2024. It features a 25° swept, supercritical wing designed by Antonov and twin rear-mounted General Electric CF34 engines. By 2025, 172 airframes had been delivered. Development In 1985, Shanghai Aircraft Manufacturing Company, now a part of Comac, launched a "troubled" partnership with McDonnell Douglas to co-produce the MD-80, a similar-looking small jet aircraft. After producing 20 MD- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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".

Supercritical Airfoil
A supercritical airfoil (supercritical aerofoil in British English) is an airfoil designed primarily to delay the onset of wave drag in the transonic speed range. Supercritical airfoils are characterized by their flattened upper surface, highly cambered ("downward-curved") aft section, and larger leading-edge radius compared with NACA 6-series laminar airfoil shapes. Standard wing shapes are designed to create lower pressure over the top of the wing. Both the thickness distribution and the camber of the wing determine how much the air accelerates around the wing. As the speed of the aircraft approaches the speed of sound, the air accelerating around the wing reaches Mach 1 and shockwaves begin to form. The formation of these shockwaves causes wave drag. Supercritical airfoils are designed to minimize this effect by flattening the upper surface of the wing. The origins of the supercritical airfoil can be traced back to the German aerodynamicist K. A. Kawalki, who designed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tenth Five-Year Plan (People's Republic Of China)
The Five-Year Plans () are a series of social and economic development initiatives issued by the Chinese Communist Party (CCP) since 1953 in the People's Republic of China. Since 1949, the CCP has shaped the Chinese economy through the plenums of its Central Committee and national party congresses. The plenums follow a customary pattern of themes; since the 14th Party Congress (1992–1997), the fifth plenum has evaluated the current five-year plan and outlined the next five-year plan. Planning is a key characteristic of the nominally socialist economies, and one plan established for the entire country normally contains detailed economic development guidelines for all its regions. In order to more accurately reflect China's transition from a Soviet-style command economy to a socialist market economy (socialism with Chinese characteristics), the plans since the 11th Five-Year Plan for 2006 to 2010 have been referred to in Chinese as "guidelines" () instead of as "plans" (). ...
