The Rolls-Royce Trent XWB is a high-bypass turbofan produced by Rolls-Royce Holdings. In July 2006, the Trent XWB was selected to power exclusively the Airbus A350. The first engine was run on 14 June 2010, it first flew on an A380 testbed on 18 February 2012, it was certified in early 2013, and it first flew on an A350 on 14 June 2013. It had its first in-flight shutdown on 11 September 2018 as the fleet accumulated 2.2 million flight hours. It keeps the characteristic three-shaft layout of the Rolls-Royce Trent, with a 3.00 m (118 in) fan, an IP and HP spool. The 84,200–97,000 lbf (375–431 kN) engine has a 9.6:1 bypass ratio and a 50:1 pressure ratio. It is the most powerful member of the Trent family.
