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 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'' 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 organizations relevant to the field at issue. For e ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Executive Aircraft
Business aircraft are aircraft typically used by companies and corporations to transport people or goods related to the needs of said businesses. Most business aircraft are general aviation aircraft variants of piston or turboprop or business jets. General aviation Piston With the growth of general aviation in the 1930s companies started to purchase single and twin-engined aircraft for business use. A need to move goods and equipment made use of different general aviation aircraft and surplus military transports. In 1963 in the United Kingdom the Maidenhead Organ Studios purchased a twin-engined Beagle B.206 to allow them to delivery electronic organs.Jackson 1974, p. 199 Turboprop For the first half of 2018, while business jets deliveries were relatively flat, new turboprops were up 10%, pressurized ones were up 12%, and King Airs were up 30%.

Hot And High
In aviation, hot and high is a condition of low air density due to high ambient temperature and high airport elevation. Air density decreases with increasing temperature and altitude. The lower air density reduces the power output from the aircraft's engine and also requires a higher true airspeed before the aircraft can become airborne. Aviators gauge air density by calculating the density altitude. An airport may be especially hot ''or'' high, without the other condition being present. Temperature and pressure altitude can change from one hour to the next. The fact that temperature decreases as altitude increases mitigates the "hot and high" effect to a small extent. Negative effects of reduced engine power due to hot and high conditions * Airplanes require a longer takeoff run, potentially exceeding the amount of available runway. * Reduced take-off power hampers an aircraft's ability to climb. In some cases, an aircraft may be unable to climb rapidly enough to clear terrain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi MRJ90
The Mitsubishi SpaceJet (, originally named ''Mitsubishi Regional Jet'') is a regional jet developed by Japanese company Mitsubishi Aircraft Corporation (MAC), a Mitsubishi Heavy Industries (MHI) subsidiary. The airframe is made mainly in aluminium with a carbon fibre composites empennage. The low-wing twinjet is powered by underwing Pratt & Whitney PW1000Gs, and was the first program to select the geared turbofan. The M90 (originally named MRJ90) should seat 86 to 96, while the smaller MRJ70 was to accommodate 70 to 80 passengers. The MRJ70 was replaced by the SpaceJet M100, stretched by 1.1 m (3 ft 7 in) to better meet US scope clauses at 76 seats with premium seating. It is comparable with the Embraer E-Jet E2. MHI first announced the concept in June 2007, then targeting certification for 2012, as the first Japanese airliner since the 1962 NAMC YS-11. After a delayed development, the maiden flight of the MRJ90 took place on 11 November 2015. In June 2019, Mitsubishi rebran ...

Embraer E-Jet E2 Family
The Embraer E-Jet E2 family are medium-range jet airliners developed by Embraer, succeeding the original E-Jet. The program was launched at the Paris Air Show in 2013. The first variant, the E190-E2, took its first flight on 23 May 2016 and was certified on 28 February 2018 before entering service with Widerøe on 24 April. The three twinjet variants share the same four-abreast narrow-body fuselage with different lengths and three different new wings, Pratt & Whitney PW1000G turbofans in two sizes, fly-by-wire controls with new avionics, and an updated cabin. Development Background In 2010, it appeared possible Embraer could directly challenge the Bombardier CSeries (now A220) with a clean-sheet five-abreast design for 100 to 150 passengers. When that market segment grew more competitive with the announcement of the Airbus A320neo and the Boeing 737 MAX, Embraer had instead committed to producing new variants of its E-Jet family of regional jets by the time of the November ...

Bombardier CRJ900
The Bombardier CRJ700, CRJ900, and CRJ1000 are a family of regional jet airliners that were designed and manufactured by Canadian transportation conglomerate Bombardier (formerly Canadair) between 1999 and 2020. Their design was derived from the smaller CRJ100 and 200 airliners, the other members of the Bombardier CRJ aircraft family. The CRJ program was acquired by Japanese corporation Mitsubishi Heavy Industries in 2020, which ended production of the aircraft. During the 1990s, Bombardier initiated development on the ''CRJ-X'', a program to produce enlarged derivatives of its popular CRJ100/200 family. Officially launched in 1997, the CRJ700's maiden flight took place on 27 May 1999; it was soon followed by the stretched CRJ900 variant. Several additional variants of the type were subsequently introduced, including the elongated CRJ1000 and the CRJ550 and CRJ705 which were modified to comply with scope clauses. Competitors included the British Aerospace 146, the Embraer E-Je ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Stretch
The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft. Similar to, but more exacting than, the usual engineering design process, the technique is highly iterative, involving high level configuration tradeoffs, a mixture of analysis and testing and the detailed examination of the adequacy of every part of the structure. For some types of aircraft, the design process is regulated by civil airworthiness authorities. This article deals with powered aircraft such as airplanes and helicopter designs. Design constraints Purpose The design process starts with the aircraft's intended purpose. Commercial airliners are designed for carrying a passenger or cargo payload, long range and greater fuel efficiency where as fighter jets are designed to perform ...
