Comac C919

CFM International is confident Comac’s C919 program is progressing on a sound basis, but the engine manufacturer does have contingency plans for the Leap-1C turbofan it has designed for the narrowbody to mitigate program risks in case further delays arise.

Leap-1A, destined to power the Airbus A320neo, began running on GE’s Peebles, Ohio testbed last September. Next in line is the Leap-1B, which will power the Boeing 737.

Engine manufacturer CFM International (Stand G23) plans to test 15 Leap engines this year as part of a development program leading to certification of the Leap-1A for the Airbus A320neo next year. Also part of the program, the Leap 1B and -1C versions are to power the upgraded Boeing 737 Max and the new Comac C919 narrowbodies, respectively. The engine’s designers promise a 15-percent fuel burn advantage over the current CFM56.

What turned out to be a big week for Boeing with the formal launch of its new 777X widebody also promises to be a big week for the engine that will power it, the GE9X. Dubai Airshow visitors can get a sneak preview of the 102,000-pound thrust turbofan through a new 3-D representation of the equipment at the GE Aviation exhibit (Chalet A9).

In May this year the French-U.S. joint venture CFM International delivered the 25,000th example of its CFM56 turbofan, which powers Boeing Next-Generation 737s and the Airbus single-aisle family. Last month the 10,000th CFM56-7B for the 737 family was delivered, while next month deliveries of CFM56-5s for Airbus will pass 8,500. As well as these two influential single-aisle aircraft lines, the CFM56 also powers the Airbus A340-200/300.
