The Rolls-Royce Trent is a family of high-bypass turbofans produced by Rolls-Royce.
It continues the three spool architecture of the RB211 with a maximum thrust ranging from 61,900 to 97,000 lbf .
Launched as the RB-211-524L in June 1988, the prototype first ran in August 1990.
Its first variant is the Trent 700 introduced on the Airbus A330 in March 1995,
then the Trent 800 for the Boeing 777 (1996),
the Trent 500 for the A340 (2002),
the Trent 900 for the A380 (2007),
the Trent 1000 for the Boeing 787 (2011),
the Trent XWB for the A350 (2015),
and the Trent 7000 for the A330neo (2018).
It has also marine and industrial variants like the RR MT30.

A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of the preceding generation engine technology of the turbojet, and a reference to the additional fan stage added. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust.
