Under the agreement GKN will be responsible for supplying the outer guide vane mount ring and rear fan case for the engine.
To minimise waste during the manufacturing process, GKN says it has developed a number of advanced fabrication and assembly techniques, including replacing traditional ring forgings with “near net shape” versions to significantly cut down machining.
GKN has also introduced electron beam and plasma welding, and reduced the weight of the rear fan case by more than 18kg through the use of chemical milling.
GKN is to manufacture Trent 1000 components at its plants in Newington, Connecticut, El Cajon, California and Mexicali, Mexico. GKN expects to supply up to 150 engine sets annually.
