Rolls-Royce has withdrawn its ultrafan from the design of Boeing's new 7K7 medium-flight aircraft, reflecting the aircraft manufacturer's development schedule in 2025 and the engine manufacturer's recent painful lessons on product reliability.
"We do not want to promise to support Boeing's new platform if we are not sure we can meet their schedule," said Chris Cholerton, president of Rolls-Royce Civil Aerospace. "We started its development before the Boeing opportunity presented itself and it must be subjected to a rigorous testing regime before offering it to customers, which, in our opinion, can not be achieved in a timely manner. the NMA. "
This decision leaves the remaining competitors, CFM International and Pratt & Whitney, in a shootout for what may be the only place to propel the plane that will eventually become the 797 of Boeing. Boeing never said he favored a single-engine or dual-engine option for the new one. jet. CFM and Pratt have long wondered about the size of the aircraft market they want to propel.
The end result promises to be a photo-finish. Neither customers nor engine builders are aware of Boeing's preference, but suppose one or both companies could win a seat under sail.

Unlike its competitors, Rolls had developed the most aggressive technology and commercial strategy of the three engine manufacturers to win a place in the power of the new small two-aisle aircraft. According to a former business leader and industry leaders, Boeing combined its brand new advanced technology Ultrafan architecture with a commercial proposition that would give Boeing shared access to its after-sales revenue, which is are rich.
