Rolls-Royce yesterday launched an enhanced performance version of the Trent XWB to fly with Singapore Airlines A350s. The Trent XWB-84 EP offers a fuel performance improvement of one percent over the original Trent XWB-84, according to the UK aero engine manufacturer. It incorporates technologies from the higher-thrust Trent XWB-97, the company’s Advance engine program and “other future technology research.”

Rolls-Royce (Stand N23) expects to deliver the first A350-900 powered with the enhanced performance engines to Singapore Airlines in the fourth quarter of 2019. The company said it will make the version available to other customers for later delivery.

Technology improvements on the XWB-84 EP include improved turbine cooling and aerodynamics, improved secondary air system and interstage sealing, and further optimization of the XWB-84’s tip clearance control system.
