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.
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.
