Visão geral

The Rolls-Royce Trent 1000 é um motor turbofan de alto bypass desenvolvido especificamente como motor de lançamento para o Boeing 787 Dreamliner. With a razão de bypass 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 arquitetura de três carretéis 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 fuselagem estreita and fuselagem larga aircraft alike.

Variantes

The Trent 1000 family has evolved significativamente 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 turbina de pressão intermediária blades and introduced new fan blades. It became the standard production variant across the entire 787 family.

História do desenvolvimento

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 turbina de pressão intermediária 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.
