Trent 800

Descripción general

The Rolls-Royce Trent 800 fue el primer motor Trent instalado en una aeronave Boeing, representando un hito comercial significativo para el fabricante británico. Developed for the Boeing 777, it ofrecía la arquitectura de tres carretes que distingue a todos los motores Trent — una elección de diseño que proporciona mejor eficiencia a velocidades parciales que la configuración de dos carretes utilizada por los competidores. The Trent 800's high-pressure core gira a su velocidad óptima independientemente del fan y el carrete de presión intermedia.

With a maximum thrust of 416 kN (93,400 lbf), the Trent 800 es uno de los motores más potentes de la familia Trent en el momento de su introducción, competing against the Pratt & Whitney PW4090 and General Electric GE90 on the 777. Operators including British Airways, Cathay Pacific, and Thai Airways International selected the Trent 800 for their 777 fleets.

Historia del desarrollo

The Trent 800 programme launched in the early 1990s as Rolls-Royce sought a share of the lucrative 777 engine market. First engine run occurred in 1993, with FAA certification following in 1995. Entry into service came in 1996 with Thai Airways International. The programme was notable for being Rolls-Royce's first opportunity to supply engines to Boeing's flagship new wide-body, reversing a historical pattern where Pratt & Whitney and General Electric dominated Boeing programmes. The Trent 800 lineage fed directly into subsequent Trent developments, establishing the core and compression architecture used in the Trent 1000 and Trent XWB.
