Trent XWB
The Rolls-Royce Trent XWB is a high-bypass turbofan produced by Rolls-Royce Holdings. In July 2006, the Trent XWB was selected to exclusively power the Airbus A350. The first engine was run on 14 June 2010, it first flew on an A380 testbed on 18 February 2012, was certified in early 2013, and first flew on an A350 on 14 June 2013.

Airbus A340
The Airbus A340 is a long-haul, long-range, wide-body passenger airliner that was developed and produced by Airbus. In the mid-1970s, Airbus conceived several derivatives of the Airbus A300, A300, its first airliner, and developed the A340 quadjet in parallel with the Airbus A330, A330 twinjet. In June 1987, Airbus launched both designs with their first orders and the A340-300 took its maiden flight on 25 October 1991. It was certified along with the A340-200 on 22 December 1992 and both versions entered service in March 1993 with launch customers Lufthansa and Air France. The larger A340-500/600 were launched on 8 December 1997; the A340-600 flew for the first time on 23 April 2001 and entered service on 1 August 2002. Keeping the eight-abreast economy cross-section of the A300, the early A340-200/300 has a similar airframe to the A330-200/300. Differences include four CFM56s instead of two high-thrust turbofans to bypass ETOPS restrictions on trans-oceanic routes, and a th ...

Trent 500
The Rolls-Royce Trent 500 is a high-bypass turbofan produced by Rolls-Royce to power the larger A340-500/600 variants. It was selected in June 1997, first ran in May 1999, first flew in June 2000, and achieved certification on 15 December 2000. It entered service in July 2002 and 524 engines were delivered on-wing until the A340 production ended in 2012. Keeping the three spool architecture of the Trent family, it has the Trent 700's 2.47 m (97.5 in) fan and a Trent 800 core scaled down. It produces up to of thrust at take-off and has a bypass ratio up to 8.5:1 in cruise. Development In 1995, Airbus began considering an engine for two new long-range derivatives of its four-engined A340, the A340-500/600. The existing A340-200/300 was powered by CFM International CFM56 engines. However, the CFM56 was at the limit of its development capability, and would be unable to power the new A340-500/-600. In April 1996, Airbus signed an agreement with GE Aviation to develop a suitab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trent 700
The Rolls-Royce Trent 700 is a high-bypass turbofan aircraft engine produced by Rolls-Royce plc to power the Airbus A330. Rolls-Royce was studying a RB211 development for the A330 at its launch in June 1987. It was first selected by Cathay Pacific in April 1989, first ran in summer 1992, was certified in January 1994 and was put into service on 24 March 1995. Keeping the characteristic three-shaft architecture of the RB211, it is the first variant of the Trent family. With its fan for a 5:1 bypass ratio, it produces of thrust and reaches an overall pressure ratio of 36:1. It competes with the General Electric CF6-80E1 and the PW4000 to power the A330. Development When Airbus launched its A330 twin-jet in June 1987, its only engine options included the General Electric CF6-80C2 and the Pratt & Whitney PW4000. Rolls-Royce was studying whether to launch a RB211-700, development of the RB211 for the A330, the long-range Boeing 767 and McDonnell Douglas MD-11, derived f ...

High-bypass Turbofan
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together. Engines that use more jet thrust relative t ...
