Rolls-Royce Trent 900
The Rolls-Royce Trent 900 is a high-bypass turbofan produced by Rolls-Royce plc to power the Airbus A380, competing with the Engine Alliance GP7000. Initially proposed for the Boeing 747-500/600X in July 1996, this first application was later abandoned but it was offered for the A3XX, launched as the A380 in December 2000. It first ran on 18 March 2003, made its maiden flight on 17 May 2004 on an A340 testbed, and was certified by the EASA on 29 October 2004. Producing up to 374 kN (84,000 lbf), the Trent 900 has the three shaft architecture of the Rolls-Royce Trent family with a fan. It has a 8.5-8.7:1 bypass ratio and a 37–39:1 overall pressure ratio. Development In July 1996, Rolls-Royce offered the Trent 900 for the proposed Boeing 747-500/600X, targeting a 2000 service entry and competing with the General Electric/Pratt & Whitney Engine Alliance. With a scaled-down Trent 800 core and a similar fan, increasing bypass ratio from 6.5 to 8.5, the engine c ... [...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 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 ...

Axial Flow
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CFM56
The CFM International CFM56 (U.S. military designation F108) series is a Franco-American family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of . CFMI is a 50–50 joint-owned company of Safran Aircraft Engines (formerly known as Snecma) of France, and GE Aviation (GE) of the United States. Both companies are responsible for producing components and each has its own final assembly line. GE produces the high-pressure compressor, combustor, and high-pressure turbine, Safran manufactures the fan, gearbox, exhaust and the low-pressure turbine, and some components are made by Avio of Italy and Honeywell from the US. The engines are assembled by GE in Evendale, Ohio, and by Safran in Villaroche, France. The completed engines are marketed by CFMI. Despite initial export restrictions, it is the most used turbofan aircraft engine in the world, in four major variants. The CFM56 first ran in 1974.Bilien, J. and Matta, R. (1989). ''The CFM5 ...

Contra-rotating
Contra-rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque. Examples include some aircraft propellers, resulting in the maximum power of a single piston or turboprop engine to drive two propellers in opposite rotation. Contra-rotating propellers are also common in some marine transmission systems, in particular for large speed boats with planing hulls. Two propellers are arranged one behind the other, and power is transferred from the engine via planetary gear transmission. The configuration can also be used in helicopter designs termed coaxial rotors, where similar issues and principles of torque apply. Contra-rotating propellers should not be confused with counter-rotating propellers, a term which describes non-coaxial propellers on separate shafts; one turning clockwise and the other counter-clockwise. Tandem-rotor helicopters such as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trent 8104
The Rolls-Royce Trent is a family of high-bypass turbofans produced by Rolls-Royce. It continues the three spool architecture of the RB211 with a maximum thrust ranging from . Launched as the RB-211-524L in June 1988, the prototype first ran in August 1990. Its first variant is the Trent 700 introduced on the Airbus A330 in March 1995, then the Trent 800 for the Boeing 777 (1996), the Trent 500 for the A340 (2002), the Trent 900 for the A380 (2007), the Trent 1000 for the Boeing 787 (2011), the Trent XWB for the A350 (2015), and the Trent 7000 for the A330neo (2018). It has also marine and industrial variants. Development Despite the RB211 success, the large civil turbofan market was dominated by General Electric and Pratt & Whitney, and Rolls-Royce share was only 8% when it was privatised in April 1987. In June, Rolls-Royce was studying whether to launch a RB211-700, a development for the Airbus A330 twin-jet, the long-range Boeing 767 and the MD-11, derived from ...

GP7200
The Engine Alliance GP7000 is a turbofan jet engine manufactured by Engine Alliance, a joint venture between General Electric and Pratt & Whitney. It is one of the powerplant options available for the Airbus A380, along with the Rolls-Royce Trent 900. Design and development Originally intended to power Boeing Commercial Airplanes' cancelled 747-500X/-600X, the engine has since been pushed for Airbus' A380-800 superjumbo. It is built around an 0.72 scale of the GE90-110B/115B core and contains a Pratt & Whitney fan and low-pressure system design. The competing Rolls-Royce Trent 900 was named as the lead engine for the then-named A3XX in 1996 and was initially selected by almost all A380 customers. However, the GE/PW engine increased its share of the A380 engine market to the point where, as of September 2007, it will power 47% of the super-jumbo fleet. This disparity in sales was resolved in a single transaction, with Emirates' order of 55 GP7000-powered A380-800s, compri ...

Virgin Atlantic
Virgin Atlantic, a trading name of Virgin Atlantic Airways Limited and Virgin Atlantic International Limited, is a British airline with its head office in Crawley, England. The airline was established in 1984 as British Atlantic Airways, and was originally planned by its co-founders Randolph Fields and Alan Hellary to fly between London and the Falkland Islands. Soon after changing the name to Virgin Atlantic Airways, Fields sold his shares in the company after disagreements with Richard Branson over the management of the company. The maiden flight from Gatwick Airport to Newark International Airport took place on 22 June 1984. The airline along with Virgin Holidays is controlled by a holding company, Virgin Atlantic Limited, which is 51% owned by the Virgin Group and 49% by Delta Air Lines. It is administratively separate from other Virgin-branded airlines. Virgin Atlantic Airways Limited and Virgin Atlantic International Limited both hold Civil Aviation Authority (CAA) Type ...
