OverviewThe Rolls-Royce Trent XWB is a high-bypass turbofan engine designed and optimized for the Airbus A350 family. It is marketed as the most efficient large aero-engine in service, delivering reduced fuel burn and CO2 emissions compared with previous-generation widebody engines.
Key messagesThe Trent XWB family comprises variants tailored to different thrust and mission requirements, including the Trent XWB-84 and Trent XWB-97. Highlights include higher-thrust options, reported high dispatch reliability and extended time-on-wing targets that support lower operating costs.
Trent XWB-84- Optimized for the A350-900.
- Selected by a majority of the world’s most profitable airlines.
- Marketed for lowest fuel consumption among current widebody engines.
- Designed for high utilisation and revenue-generating operations.
Trent XWB-97- Highest-thrust variant in the Trent XWB family, developed for the A350-1000.
- Reported dispatch reliability up to 99.9% for high-thrust configurations.
- Deployed across passenger and freighter applications.
Performance & operational benefits- Lower fuel burn and CO2 emissions versus previous-generation widebody engines (manufacturer-cited figures).
- Reported multi-million dollar annual fuel savings per aircraft in typical operator scenarios.
- Extended time-on-wing targets and reduced removal frequency compared with prior-generation engines.
Aftermarket support and trainingRolls-Royce provides global aftermarket support, maintenance services and accredited training for the Trent XWB through its network of service centres and training facilities.
Available customer documents and guidanceOperators have access to product support documentation and training materials covering familiarisation, line and base maintenance and borescope inspection procedures.
