voila ce qui est publié sur la page Wiki (en anglais, rien en français comme d'hab) sur le Trent 1000

on reparle de la ''dominance électrique'' de la bête :
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 spool instead of the high-pressure 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.
