The Rolls-Royce Trent 1000 is a turbofan engine, developed from earlier Trent series engines. The Trent 1000 powered the Boeing 787 Dreamliner on its maiden flight, and on its first commercial flight.The Trent 1000 family makes extensive use of technology derived from the Trent 8104 demonstrator. In order to fulfill Boeing's requirement for a "more-electric" engine, 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. A 2.8 m (110 in) diameter swept-back fan, 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, and the use of more monolithic parts reduces the parts count to minimise maintenance costs. A tiled combustor is featured.
