Descripción general
The Rolls-Royce Trent 1000 es un motor turbofán de alto bypass desarrollado específicamente como motor de lanzamiento para el Boeing 787 Dreamliner. With a bypass ratio of 10:1 and a fan diameter of 2.85 metres, estaba entre los turbofanes comerciales de gran tamaño más eficientes en combustible en su introducción. The engine comparte la característica arquitectura de tres carretes presente en toda la familia Trent, permitiendo que cada carrete opere a su velocidad de rotación óptima.
The Trent 1000 entered service in 2011 junto con the 787-8 and compite directamente con el General Electric GEnx on the 787 platform. Ambos motores se ofrecen como alternativas, dando a las aerolíneas la opción de elegir entre proveedores — un arreglo relativamente raro en los modernos narrowbody and widebody aircraft alike.

Variantes
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.

Historia del desarrollo
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.
