A Trent 1000 powered 787 is 20% more fuel efficient than the 767 it replaces

1

IP power offtake efficiently drives the aircraft electrical systems while improving engine handling and operability at low power

2

Heated Engine Section Stators (ESS) deliver advanced ice protection, reducing operational burden

3

Advanced proactive Engine Health Systems monitor performance real time in-flight

4

New HP compressor with more efficiency. Proven on the NEWAC demonstrator programme and Trent XWB

5

Blisks are lighter and more efficient. Proven on the Trent XWB

6

New HP turbine with advanced cooling system to enable more thrust and more efficiency

7

10:1 bypass ratio makes it the most efficient Trent engine in service and the quietest engine on the Boeing 787

8

Low hub-tip ratio maximises airflow and improves FOD protection to deliver superior retention performance

9

Adaptive HP cooling system lowers fuel burn and delivers better engine performance retention

Optimised for the Boeing 787 Dreamliner Family

Part of the Trent family, the three-shaft architecture of the Trent 1000, tailored to the Boeing 787 Dreamliner, adds value to operators and owners. Advanced technologies such as soluble core high pressure turbine blades provide life-cycle cost benefits. Smart design features such as the 3D aero design compressor and low hub:tip ratio fan ensure the engine is efficient and reliable across a wide range of operations. These attributes result in the best engine for the Boeing 787, both commercially and technically

Capitalising on the architecture and technologies of previous generations of Trent engine, the Trent 1000 has been designed and optimised to power the Boeing 787 Dreamliner. The Trent 1000 powered Boeing 787 Dreamliner is 20% more efficient than the Boeing 767 aircraft it replaces.

The Trent family's unique 3 shaft design makes every Trent engine shorter, stiffer, lighter and more FOD (Foreign Object Damage) resistant than its equivalent 2 shaft engine. This results in significantly less performance deterioration and delivers an additional fuel burn benefit of 1% through life.

The following technologies have been introduced on the Trent 1000 to optimise the engine for the all-electric 787 aircraft:

IP power offtake
The IP power offtake efficiently drives the aircraft electrical systems while improving engine handling and operability at low power. The all-electric architecture of the Boeing 787 aircraft requires that no bleed air is taken from the engine, but up to 500kW of power is extracted from each engine to drive the aircraft systems.

10:1 bypass ratio 
The highest bypass ratio of any Trent makes it the most efficient Trent engine in service and the quietest engine on the Boeing 787 aircraft today. Over 85% of the engine’s thrust is generated by the 2.8m diameter fan.

Low hub:tip ratio
The Trent 1000 fan has a very low hub:tip ratio. This maximises airflow at a given fan diameter and improves FOD protection to deliver superior performance retention.

Anti-icing features 
The Trent 1000 engine has a number of features to safeguard against core icing including extra strengthening of IP compressor blades and a heated ESS (Engine Section Stator) system which delivers advanced ice protection, reducing operational burden in cold or high-moisture environments.
