An exciting new chapter for the
Trent 1000

An exciting new chapter for the Trent 1000

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 achievement of a significant milestone in transforming our customers experience of operating their Trent 1000 powered 787s, with the certification of our Durability Enhancement package for the Trent 1000 TEN

So, what is new?...

A new Durability Enhancement package

Our new Durability Enhancement package for the TEN is focused on increasing engine time on-wing (TOW) whilst also reducing emissions. A key element of this Durability Enhancement package is a re-engineered high-pressure turbine blade (HPTB) to improve durability. By improving the cooling performance of the blade, we have more than doubled the blade life and therefore more than doubled the engine TOW.

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

Similar improvements in HPTB durability have already been made to earlier variants of the Trent 1000 and the Trent 7000 engines, and these are already delivering significant benefits in service. With certification achieved, we can now begin incorporating the Durability Enhancement package into existing Trent 1000 TEN customer engines as part of their TotalCare programme.

We are not stopping there; a second package of hot-section enhancements is already in development as Phase 2 of our Durability Enhancement activity and will deliver a further improvement in time on wing of up to 30%.

Already proven to deliver

Confidence in Phase 1 of our 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 partners in 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 two years of operation their condition is surpassing our original expectation and proven to more than double TOW. This real-life service experience gives us and our customers high confidence that we will realise similar benefits in time on wing improvements on the TEN. Our industrial plan is in place with new parts already available to support both in-service and new production engines, and we are excited to have this transformational package available to start going into service with all our Trent 1000 TEN customers.

Ready to enable rapid incorporation

Our focus now turns to enabling the rapid incorporation of this Durability Enhancement package through the fleet such that our customers can start to realise the benefits within their operation. To this end we have been investing in our MRO capacity to achieve both near term tactical and longer-term strategic goals.

Just over the past 6 months 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 incorporation of the Durability Enhancement package. All three of these facilities are already spooling up having reworked and despatched their first Trent 1000 engines.

With certification now achieved and parts on the shelf we can now launch incorporation across the overhaul network. Our plan is to have complete incorporation across the whole Trent 1000 TEN service fleet by the end of 2027.

We are now good to go!
