Overview
The Rolls-Royce Trent 1000 is a high-bypass turbofan engine developed specifically as the launch engine for the Boeing 787 Dreamliner. With a bypass ratio of 10:1 and a fan diameter of 2.85 metres, it was among the most fuel-efficient large commercial turbofans at its introduction. The engine shares the characteristic three-spool architecture found across the entire Trent family, allowing each spool to operate at its optimal rotational speed.
The Trent 1000 entered service in 2011 alongside the 787-8 and competes directly with the General Electric GEnx on the 787 platform. Both engines are offered as alternatives, giving airlines a choice between suppliers — a relatively rare arrangement on modern narrowbody and widebody aircraft alike.

Variants
The Trent 1000 family has evolved significantly since its introduction:
- Trent 1000-A/B/C: Initial production variants for the 787-8, certified at thrust ratings between 64,000 and 74,000 lbf.
- Trent 1000-D/E/G: Variants for the stretched 787-9, with refined aerodynamics and updated materials.
- Trent 1000-TEN: Introduced in 2017 for the 787-10, TEN stands for Thrust, Efficiency, and New technology. This variant addressed durability problems found in earlier intermediate-pressure turbine blades and introduced new fan blades. It became the standard production variant across the entire 787 family.
Aircraft Applications
- Boeing 787-8 — launch application
- Boeing 787-9
- Boeing 787-10
Development History
Rolls-Royce launched the Trent 1000 programme in 2004 after winning a share of the 787 engine competition. The first engine ran in 2006, and FAA certification was achieved in 2007. Early service experience revealed unexpected wear on the intermediate-pressure turbine blades, leading to mandatory inspection intervals and some groundings of affected aircraft between 2018 and 2020. Rolls-Royce invested heavily in blade redesign and fleet remediation, ultimately completing the fix with the Trent 1000-TEN configuration. By 2023 the blade durability issues were largely resolved, and the programme returned to normal operating tempos.
