An exciting new chapter for the
Trent 1000

An exciting new chapter for the Trent 1000

Our Trent 1000 engine fleet has surpassed 19 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 pleased to announce an exciting new chapter for the Trent 1000.
So, what is new?

A new Durability Enhancement package

We are making great progress on a new Durability Enhancement package, which will increase 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.

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. 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 delivering significant benefits in service. Customers who have existing Trent 1000 TEN engines that pre-date the introduction of the durability enhancement package will also benefit. The package will be installed into the engines at their first scheduled full refurbishment under every customer’s 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%.

Progressing with certification and availability

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. This same new blade design is already in service on the Trent 7000 and after almost two years of operation their condition is proving to be aligned with our expectations of more than doubling TOW and giving further confidence that we will realise the expected time on wing improvements on the TEN. The certification programme is progressing and after recently securing engine certification with EASA, it is great to see the Boeing 787 Dreamliner used for flight testing take to the sky and begin the certification flight test programme. All our efforts are focused on continuing to support the aircraft-level certification in collaboration with Boeing, and enabling our industrial plan to have this package available for new production and service retrofit in early 2025. Watch this space for further progress updates.

More about the Trent 1000

Capitalising on the three-shaft architecture of the Trent engine family and incorporating the latest in materials, component and subsystem design and technology, the Trent 1000 was specifically designed and optimised to power the more-electric 787 Dreamliner. It has the highest bypass ratio of any engine in the Trent family and is recognised for being one of the quietest widebody engines in service today.

Since entry into service in 2011, we have been continuously improving both the fuel efficiency and the capability of the Trent 1000.

Did you know that the latest version of the Trent 1000 is the TEN? This is the current production standard and powers all three variants of the Boeing 787 family.

TEN stands for Thrust, Efficiency and New technology, reflecting the enhancements it delivers – more thrust and better fuel burn, enabled by new technology that has been matured through technology demonstrator programs and validated on the Trent XWB engine. All of this ensures that the Boeing 787 Dreamliner family continues to deliver opportunities and value for airlines and passengers around the world.
