ATK announced the award of a contract valued at more than $50m from Rolls-Royce, to produce aft fan composite cases for the new Trent XWB-97 engine. The contract has the potential to grow to more than $200m. This Rolls-Royce engine is the sole engine now available to power the Airbus A350-1000 aircraft variant. The life-of-type contract with Rolls-Royce further highlights ATK’s key role as a provider of large-scale composite components for commercial aircraft and engines. ATK has been producing aft fan cases for the Rolls-Royce Trent XWB-84 engines since 2009.
