CJ-1000A
The AECC CJ-1000A ( Chang Jiang-1000A/长江-1000A) is a Chinese high-bypass turbofan jet engine currently in development. Design The CJ-1000A is developed for the Comac C919 narrow-body airliner with a thrust of . It has a diameter of and a length of , to be compared with the CFM LEAP-1C diameter and length. It uses a similar two-spool configuration, with a one-stage fan, three-stage booster, 10-stage high-pressure compressor, two-stage high-pressure turbine and six-stage low pressure turbine, compared to the Leap-1C seven stages. Its 18 wide-chord fan blades are made of hollow titanium like those of Rolls-Royce Plc., and its single annular combustor uses 3D printed fuel nozzles. Development A model of the CJ-1000Al was exhibited at the AVIC booth of the September 2011 Beijing Air Show, and was expected to be completed in 2016. At the time, entry into service was targeted for 2020 and a possible cooperation with MTU Aero Engines was studied. In 2013, Avic Engine subs ...

Comac C919
The Comac C919 is a narrow-body airliner developed by Chinese aircraft manufacturer Comac. The development program was launched in 2008. Production of the prototype began in December 2011, with the first prototype being ready on 2 November 2015 and having its maiden flight on 5 May 2017. The aircraft received its airworthiness certification from the Civil Aviation Administration of China on 29 September 2022 and the first operational airframe intended for commercial service was delivered to launch customer China Eastern Airlines on 9 December 2022 in Shanghai. The aircraft, primarily constructed with aluminium alloys, is to be powered by either CFM International LEAP or ACAE CJ-1000A turbofan engines, and be able to carry 156 to 168 passengers in a normal operating configuration up to 5,555 km (3000 nmi). Naming In the model number, the ''C'' stands for "Comac". The ''C'' also has the implication that forms an "ABC" parallel situation with Airbus and Boeing. Developmen ...

CFM International LEAP
The CFM International LEAP ("Leading Edge Aviation Propulsion") is a high-bypass turbofan engine produced by CFM International, a 50–50 joint venture between American GE Aviation and French Safran Aircraft Engines (formerly Snecma). It is the successor of the successful CFM56 and competes with the Pratt & Whitney PW1000G to power narrow-body aircraft. Design The LEAP's basic architecture includes a scaled-down version of Safran's low pressure turbine used on the General Electric GEnx, GEnx engine. The fan has flexible blades manufactured by a Out of autoclave composite manufacturing, resin transfer molding process, which are designed to untwist as the fan's rotational speed increases. While the LEAP is designed to operate at a higher pressure than the CFM56 (which is partly why it is more efficient), CFM plans to set the operating pressure lower than the maximum to maximize the engine's service life and reliability. Currently proposed for the LEAP is a greater use of composite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aviadvigatel PD-35
The Aviadvigatel PD-14 (previously known as PS-12) is a high-bypass turbofan being developed by Aviadvigatel to power the Irkut MC-21 twin-jet airliner. It is a 14 tf (30,865 lbf) thrust powerplant. Development In December 2009, the PD-14 was developed to be 15% more efficient than its PS-90A2 predecessor to be installed on the MS-21 and the Ilyushin Il-276. The PD-14 was announced in early 2010 with its development cost estimated at RUB 35 billion (US$1.1 billion). In April 2010, Aviadvigatel was expecting to start its certification procedure in 2012. Its core was first tested on 26 November 2010. It was displayed for the first time at the 2013 MAKS air show. Flight tests began in 2015 on an Ilyushin Il-76. Between December 2016 and May 2017, the PD-14 operational performance and working efficiency at all altitudes and speeds were assessed on the Il-76 testbed aircraft at Gromov Flight Research Institute near Moscow.

WS-10
The Shenyang WS-10 (), codename Taihang, is a turbofan engine designed and built by the People's Republic of China. Chinese media reported 266 engines were manufactured from 2010 to 2012 for the J-11 program. Unofficial estimates placed production at more than 300 units by May 2015. Description The WS-10A is advertised as an engine with thrust. It has full authority digital engine control (FADEC). Development The WS-10 is derived from the CFM56 with the experience gained from the Woshan WS-6 turbofan project, which was abandoned at the start of the 1980s. The WS-10 project was reportedly started by Deng Xiaoping in 1986 to produce an engine comparable to the Saturn AL-31. The work was given to the Shenyang Aeroengine Research Institute (606 Institute) of the Aviation Industry Corporation of China (AVIC). Initial production models suffered quality issues from the early direct use of AL-31 control systems. Furthermore, Salyut refused to sell source code of the full authorit ...

Shanghai
Shanghai (; , , Standard Mandarin pronunciation: ) is one of the four direct-administered municipalities of the People's Republic of China (PRC). The city is located on the southern estuary of the Yangtze River, with the Huangpu River flowing through it. With a population of 24.89 million as of 2021, Shanghai is the most populous urban area in China with 39,300,000 inhabitants living in the Shanghai metropolitan area, the second most populous city proper in the world (after Chongqing) and the only city in East Asia with a GDP greater than its corresponding capital. Shanghai ranks second among the administrative divisions of Mainland China in human development index (after Beijing). As of 2018, the Greater Shanghai metropolitan area was estimated to produce a gross metropolitan product (nominal) of nearly 9.1 trillion RMB ($1.33 trillion), exceeding that of Mexico with GDP of $1.22 trillion, the 15th largest in the world.

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".

Thrust Specific Fuel Consumption
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence ''thrust-specific''. This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit fuel consumed. TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton). Mass of fuel is used, rather than volume (gallons or litres) for the fuel measure, since it is independent of temperature. Specific fuel consumption of air-breathing jet engines at their maximum efficiency is more or less proportional to exhaust speed. The fuel consumption ''per mile'' or ''per kilometre'' is a more appropriate comparison for aircraft that travel a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
