Rolls-Royce improves XWB-84 engine for A350-900.

Rolls-Royce is set to flight-test an improved fan for the XWB-84 engine which will run in early 2015.

The revised design “is over 100 lb. lighter than the current version” said XWB program director Simon Burr.

“There is a weight advantage but it also helps with the industrial process. That was part of the learning from the early stages and it also helps in terms of the production system.”

The new fan will be cut into the production line in the 3Q/2015, following the completion of flight tests that will check for relevant changes related to the power management algorithms in the electronic engine control system.
