The Rolls-Royce large civil aero engine Trent XWB-97, the latest variant of the Trent XWB, received formal flight certification, leading the way to the engine entering into service later this year. The news comes only a week after another Rolls-Royce Trent engine – Trent 1000 TEN received full flight certification.

Certification of the 97,000lb thrust engine, which will exclusively power the Airbus A350-1000, builds on the 84,000lb thrust version of the Trent XWB which entered passenger service in 2015, powering the Airbus A350-900.

“We are very proud of the success of the Trent XWB programme and look forward to the newest variant of the engine entering into service later this year,” said Andrew Gwynne, Rolls-Royce, Chief Engineer – Trent XWB. “We have worked closely with the teams at Airbus and EASA to achieve this certification and would like to thank them for their support.”

Certification was granted by EASA (European Aviation Safety Agency. Over 1,600 wide body jet engines are already ordered by more than 40 customers worldwide. It comes less than a week after the Trent 1000 TEN engine, upgraded model for the troubled Trent 1000, which will power all variants of the Boeing 787 Dreamliner, received a similar level of certification from EASA.

The Trent XWB-97’s increased level of thrust relative to the Trent XWB-84 is achieved through a combination of new high-temperature turbine technology, a larger engine core and advanced fan aerodynamics.
