Airbus A340
The Airbus A340 is a long-range, wide-body passenger airliner that was developed and produced by Airbus. In the mid-1970s, Airbus conceived several derivatives of the A300, its first airliner, and developed the A340 quadjet in parallel with the 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. Differences include four CFM56s instead of two high-thrust turbofans to bypass ETOPS restrictions on trans-oceanic routes, and a three-leg main landing gear instead of two ...

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 GEnx engine. The fan has flexible blades manufactured by a 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 materials, a blisk fan in the compressor, a second-generatio ...

General Electric Affinity
The General Electric Affinity was a turbofan developed by GE Aviation for supersonic transports. Launched in May 2017 to power the Aerion AS2 supersonic business jet, its initial design was completed in 2018 before its detailed design in 2020 for the first prototype production. GE Aviation discontinued development of the engine in May 2021. Its high-pressure core is derived from the CFM56, matched to a new twin fan low-pressure section for a reduced bypass ratio better suited to supersonic flight. Development At the May 2017 EBACE, Aerion announced its selection of GE Aviation to power the Aerion AS2 supersonic business jet. GE then launched the Affinity program. The final engine configuration is a core with billions of operational hours – suggesting the CFM56 – and a new low-pressure section optimised for supersonic speed. The Affinity high-pressure core is adapted from the CFM56 and the GE F101/ F110 military engines. In February 2018, Aerion released the GE engi ...
