A320s to get new engine, but Rolls-Royce not in the frame

These are the LEAP-X powerplant from the Franco-American CFM International consortium that makes all the current series 737 engines, and the Pratt & Whitney PurePower PW110OG. This move will reduce fuel consumption and C02 emissions by around 15%, it is said. Rolls-Royce, which supplies the existing engine for the A320 family, in partnership with Pratt & Whitney, has decided not to take part in the 're-engining' exercise, raising the prospect that it will miss out on sales worth billions of dollars. But Rolls-Royce is, say experts, pinning its hopes on a radical engine design for when Boeing and Airbus introduce entirely new versions of their single-aisle aircraft, probably in the 2020s. According to Flightglobal, the company has said: "We have been unable to construct an acceptable business case for re-engining and have elected not to participate in the A320neo [new engine option]. "We are confident that we will have competitive product and service offerings available when our customers launch new aircraft programmes in the future." Such new aircraft with new engines will deliver fuel savings of between 25 and 30%, it is suggested. The Airbus move now puts pressure on Boeing, which has also been considering re-engining its 737 competitor aircraft.
