the Trent 1000 is a bleedless design, with power take-off from the intermediate-pressure (IP) spool instead of the high-pressure (HP) spool found in other members of the Trent family. with a smaller diameter hub to help maximize airflow, was specified. The bypass ratio has been increased over previous variants by suitable adjustments to the core flow. A high pressure ratio along with contra-rotating the IP and HP spools improves efficiency,[6] and the use of more legacy components reduces the parts count to minimise maintenance costs. A tiled combustor is featured.
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
