Rolls-Royce has confirmed that Phase 3 of its multi-phase enhancement programme for the Trent XWB-97 engine is now underway, focusing on extending engine durability while maintaining fuel efficiency and reliability. The initiative builds on earlier upgrade phases already in service and follows seven years of operational data from global airlines.

The Trent XWB-97, powering the Airbus A350-1000, is currently the world’s most widely used large aero engine, delivering high utilisation rates for leading airlines. However, operations in extreme conditions – particularly hot and dusty environments such as the Middle East – have highlighted specific durability challenges.

Phase 3 introduces redesigned turbine blades, new seal segments and enhanced combustor cooling, aiming to increase engine resilience under high temperatures and abrasive conditions without compromising performance. A test programme at the company’s Derby facility simulates real-world desert environments to validate the upgrades before entry into service, scheduled for 2028.

Ben Williams, Vice President of Programmes at Rolls-Royce, stated: “This phase represents a significant investment in the long-term reliability of the Trent XWB-97. Our goal is to deliver longer time on wing and greater operational confidence for airlines operating in demanding climates.”

The enhancements form part of Rolls-Royce’s broader £1 billion investment into its Trent engine family, which powers more than 50% of modern widebody aircraft worldwide.
