CFM International, the General Electric/Snecma joint venture, expects to begin a second phase of ground testing for its 3-D woven resin transfer molding fan with its Moteur à Aubes de Soufflante en Composite Taille (Mascot) 2 fan-demonstrator engine. The fan is “foundational technology” for the CFM Leap engine that is scheduled to enter service in 2016.

The 10th China International Aviation and Aerospace Exhibition–popularly known as Airshow China–will be held in Zhuhai, Guandong from Nov. 11-16, 2014. Started in 1996 as the Zhuhai Airshow, it has since been held biennially. It is the only international aerospace trade show in China with a flying display that is endorsed by the State Council in Beijing.
On May 2, CFM International froze the design for the Leap-1B engine that is to power Boeing’s 737Max narrowbody and, eventually, the Boeing Business Jets derived from the airliner. The engine manufacturer, which is a joint venture between Snecma and GE, has said it on track to achieve the first full engine test in mid-2014, followed by initial flight testing in 2015 and powerplant certification in 2016. The 737Max is due to enter service in 2017.
CFM International last week froze the design of the Leap engine variant destined to power Boeing’s new 737 Max narrowbody. The Snecma-GE joint venture has said it expects to achieve the first full engine test of the Leap-1B in the middle of next year, followed by initial flight-testing in 2015 and powerplant certification in 2016. Boeing expects the 737 Max to enter service in 2017.
China’s Spring Airlines has ordered CFM56-5B engines to power a pair of new Airbus A320s that it is due to received in January and July 2014. Engine maker CFM International announced the $40 million deal on November 14 at Airshow China 2012.
CFM faces some uncertainties surrounding its Leap-1C turbofans for the Comac C919 narrowbody, although the engine program schedule calls for that variant of the three-member Leap family to go to test first.
CFM International has expanded its TruEngine program coverage to include content assurance guarantee (CAG) for subsequent buyers of qualified CFM56 engines. The engine maker launched the CAG in response to customer requests for more assurance of asset value upon the sale of a qualified CFM56. With this guarantee, customers who purchase a qualified CFM56 are entitled to a 50-percent credit on replacement parts if, at the first shop visit after transfer of ownership, any parts or repairs found in the engine are not original CFM parts or CFM-authorized repairs.
Boeing and China’s Comac opened a new joint-venture facility in Beijing last week to study biofuels refinement and improvements to air traffic management. Its first project is to study the prospects for refining used cooking oil, often described in China as “gutter oil,” into sustainable aviation biofuel.
Major orders for the new CFM International Leap-X turbofan engine are due to be announced during the first four days of the Paris show, intensifying the battle with Pratt & Whitney to power the Airbus A320neo. “We’re set for this to be one of our best shows ever,” said the company.
Engine maker CFM has chosen sides in the debate between proponents and opponents to composite materials on turbofan moving parts by introducing fibers woven in three dimensions for fan and even low-pressure turbine (LPT) blades. The bet on this next-generation composite manifests itself on the Snecma-General Electric venture's Leap-X “advanced turbofan” program.
