The Rolls-Royce Trent 1000 is a turbofan family developed to power the Boeing 787 Dreamliner. Its development includes the Trent 1000 TEN, whose name means Thrust, Efficiency and New Technology. EASA certified TEN in July 2016 and described its use of technology from the Trent XWB and Advance programmes to improve thrust and efficiency. The family encompasses multiple approved configurations; TEN and earlier engine standards have configuration-specific ratings and limitations.
