Airbus A320neo engine supplier Pratt & Whitney is confident in competing against the CFM Leap engine in supply competitions, and continues to trumpet the PW1100G geared fan technology is superior to the conventional Leap design.

Just prior to and during the Paris air show in June CFM's order momentum strengthened, giving the manufacturer some traction against P&W, which until that time had virtually dominated A320neo family orders since the programme launch late last year.

But P&W seems undeterred by CFM's recent order rebound. Speaking at the International Aviation Forecast Summit hosted by the Boyd Group, P&W vice-president of marketing Paul Finklestein stated CFM with the conventional design of the Leap is doing everything it can to approach the benefits of the geared turbofan. "But at the end of the day we think we have a significant advantage."

With the 12:1 bypass ratio Finklestein said the geared turbofan offers the largest step in bypass ratio ever seen. The fan diameter of the PW1100G is on the A320neo is 205.7cm (81in).

The fan diameter of the Leap engines powering the A320neo is 198cm (78in), with a bypass ratio of 11. Airbus confirmed the bypass ratio of the Leap to Air Transport Intelligence.

CFM is the exclusive engine provider for the re-engined Boeing 737 Max family, and Boeing has said it would narrow fan size choices from 168cm or 173cm (66in or 68in) during the next several weeks.
