Introducing the
Trent 1000 XE

Introducing the Trent 1000 XE

Our Trent 1000 engine fleet has surpassed 21 million in service flying hours on the Boeing 787 Dreamliner aircraft family, carrying more than 350 million passengers around the globe since its entry into service in 2011. During this time, we have continuously improved the fuel efficiency, capability and durability of the Trent 1000 and our engineers continue to explore opportunities to improve the engine and in-service support, to ensure we are always delivering the maximum value to our customers.

We are therefore excited to announce the introduction of the Trent 1000 XE which incorporates a suite of durability enhancements, transforming our customers’ experience of operating their Trent 1000 powered 787s.

So, what is new?...

Enhanced durability

At the heart of the Trent 1000 XE is a new Durability Enhancement package focused on increasing engine time on-wing (TOW) whilst also reducing emissions when compared to the Trent 1000 TEN. A key element of this Durability Enhancement package is a new high-pressure turbine blade (HPTB). We have introduced a comprehensive re-design of the HPTB cooling system to enable a 40% increase in the cooling flow and matched this with a re-design of the HPTB cooling hole configuration.

This delivers a reduction in core blade temperature, and a greater uniformity in blade aerofoil surface cooling which enables the bade to survive significantly longer in the high temperature environment within which it operates.

The package also includes improvements to reduce the emissions, which together with the exceptionally low fuel burn of the engine, is future proofing the Trent 1000 XE for a more sustainable world.

This new HPTB package will be complemented by a further package of hot-section enhancements which have already completed development testing and planned for availability in 2026. The combined result of all these durability enhancements is the Trent 1000 XE delivering a time on wing for our customers that is three times that of the Trent 1000 TEN they have been operating to date.

Already proven to deliver

Confidence in Trent 1000 XE Durability Enhancement package has been demonstrated through a rigorous engine ground test programme where we have pushed the engine beyond the certification requirements for this new HPTB.

Certification of this package is the culmination of years of rigorous design, development and validation work involving thousands of people across our organisation and beyond, including our airframe partner Boeing. To inform this design change we have utilised in-service data from our advanced engine health monitoring system and sophisticated thermal modelling to identify improvements to the efficiency of the HPTB cooling system.

This same new blade design is already in service on the Trent 7000 and after over three years of operation their condition is surpassing our original expectation and proven to near tripling time on wing in service for some customers. This real-life service experience gives us and our customers high confidence that we will realise similar benefits in time on wing improvements with the Trent 1000 XE. Our industrial plan is in place with new parts available, and so we are excited to have this transformational package available not only for new 787 Dreamliner customers but also for incorporation in service to enable existing Trent 1000 TEN customers to upgrade to the Trent 1000 XE.

Rapid incorporation and upgrade

Our focus now turns to enabling the rapid incorporation of this Durability Enhancement package through the fleet. We are upgrading all Trent 1000 TEN engines to the Trent 1000 XE so that our customers can start to realise the benefits within their operation as soon as possible. To this end we have been investing in our MRO capacity to achieve both near term tactical and longer-term strategic goals.

We have brought online additional new MRO capacity at three separate locations in the UK, Germany and Singapore. These facilities have been commissioned to perform Trent 1000 repair and overhaul and more specifically to support the rapid upgrade of the Trent 1000 TEN to the Trent 1000 XE. All three of these facilities are already spooling up having reworked and despatched their first Trent 1000 engines.

With certification of the Phase one Durability Enhancement package now achieved and our second phase of hot-section enhancements available in 2026, the upgrade of the entire fleet from Trent 1000 TEN to Trent 1000 XE is already well underway and our plan is to have this complete by the end of 2027.

We are now good to go!
