The Rolls-Royce Trent 800 is a high-bypass turbofan produced by Rolls-Royce plc, one of the engine options for the first-generation Boeing 777 variants, also known as 777 Classics. Launched in September 1991, it first ran in September 1993, was granted EASA certification on 27 January 1995, and entered service in 1996. It reached a 40% market share, ahead of the competing PW4000 and GE90, and the last Trent 800-powered 777 was delivered in 2010. The Trent 800 has the Trent family three shaft architecture, with a 280 cm (110 in) fan. With a 6.4:1 bypass ratio and an overall pressure ratio reaching 40.7:1, it generates up to 413.4 kN (92,900 lbf) of thrust.
