Rolls-Royce Trent

The Rolls-Royce Trent is a family of high-bypass turbofans for large airliners, produced by Rolls-Royce and continuing the three-spool architecture of the RB211 of 1972. Thrust across the family ranges from 61,900 to 97,000 pounds-force (275 to 431 kilonewtons). It was launched in June 1988 as the RB211-524L, and the prototype first ran in August 1990. Rolls-Royce chose to offer an engine for almost every large civil airliner from a common core to lower development cost, and the three-shaft layout lets each spool be scaled separately. The first variant, the Trent 700, entered service on the Airbus A330 in March 1995, followed by the Trent 800 for the Boeing 777, the Trent 500 for the A340, the Trent 900 for the A380, the Trent 1000 for the Boeing 787, the Trent XWB for the A350 and the Trent 7000 for the A330neo. Marine and industrial derivatives such as the MT30 also exist. The family is named after the River Trent in the English Midlands.
