TSS Boeing 777 Rolls-Royce Trent 895 Pilot Edition Sound Package

The Rolls-Royce Trent is a British family of three-spool, high-bypass turbofan aircraft engines manufactured by Rolls-Royce plc. All are developments of the RB211 with thrust ratings of 53,000 to 97,000 pounds-force (240 to 430 kN).

Versions of the Trent are in service on the Airbus A330, A340, A350, A380, Boeing 777, and 787. The Trent has also been adapted for marine and industrial applications.

At the same time, Boeing was investigating an enlarged development of its 767 model dubbed the 767X, for which Rolls-Royce proposed the Trent 760. By 1990 Boeing abandoned its planned 767X and instead decided to launch a new, larger aircraft family designated 777 with a thrust requirement of 80,000 lbf (360 kN) or more. The Trent 700's 2.47 m (97 in) diameter fan would not be big enough to meet this requirement, so Rolls proposed a new version with a 2.80 m (110 in) fan diameter, designated Trent 800.

Testing of the Trent 800 began in September 1993, and certification was achieved in January 1995. The first Boeing 777 with Trent 800 engines flew in May 1995, and entered service with Cathay Pacific in April 1996.

Initially Rolls-Royce had difficulty selling the engine; British Airways, traditionally a Rolls-Royce customer, submitted a large order for the competing General Electric GE90 engine. The breakthrough came when it won orders from Singapore Airlines, previously a staunch Pratt & Whitney customer, for its 34 Boeing 777s. The Trent 800 has a 41% share of the engine market on the 777 variants for which it is available.
