Rolls-Royce is making further performance improvements to its Trent 700 engine, which powers the Airbus A330. Technologies from the Trent 1000, Trent XWB and BR725 engines are being incorporated into this latest Trent 700 variant, increasing efficiency by at least 1 percent.

The improvement program, which will also focus on engine service support, is expected to be finalized this year, with enhanced engines set to enter service in 2015. Improvements will also be available for retrofit to the current engine fleet.

The program, announced here at the Farnborough show, is in addition to enhancements introduced in 2009 that incorporated Trent 900 and Trent 1000 technology, delivering a 1-percent reduction in fuel consumption.
