Rolls-Royce Trent 700

The Rolls-Royce Trent 700 is a high-bypass turbofan aircraft engine produced by Rolls-Royce plc to power the Airbus A330. Rolls-Royce was studying a RB211 development for the A330 at its launch in June 1987. It was first selected by Cathay Pacific in April 1989, first ran in summer 1992, was certified in January 1994 and was put into service on 24 March 1995. Keeping the characteristic three-shaft architecture of the RB211, it is the first variant of the Trent family. With its 97.4 in (247 cm) fan for a 5:1 bypass ratio, it produces 300.3–316.3 kN (67,500–71,100 lbf) of thrust and reaches an overall pressure ratio of 36:1. It competes with the General Electric CF6-80E1 and the PW4000 to power the A330.
