Visão geral

The Rolls-Royce Trent 800 foi o primeiro motor Trent instalado em uma aeronave Boeing, representing a significant commercial milestone for the British manufacturer. Developed for the Boeing 777, it offered the arquitetura de três carretéis that distinguishes all Trent engines — a design choice that provides better part-speed efficiency than the dois carretéis configuration used by competitors. The Trent 800's high-pressure core spins at its optimal speed independently of the fan and intermediate-pressure spool.

With a maximum thrust of 416 kN (93,400 lbf), the Trent 800 is one of the most powerful engines in the Trent family at the time of its introduction, 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.

História do desenvolvimento

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 fuselagem larga, 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.
