UK-based aerostructures and components company GKN Aerospace has finalized a risk-and-revenue-sharing partnership (RRSP) with Pratt & Whitney over the engine manufacturer’s PurePower PW1900 Geared Turbofan (GTF) engine.
The agreement, which could be worth up to $2.5 billion over the life of the programme, covers the supply of key components for the engine, which will power the Embraer 190 and 195-E2 regional jets.
As part of the agreement, GKN Aerospace will take a 7% share in the engine programme.
Under the RRSP, GKN Aerospace Engine Systems will take on design and manufacturing responsibility for the turbine exhaust case and intermediate compressor case for the PW1900G, as well as the manufacture of the engine’s low pressure turbine shaft and fan case mount rings.
GKN Aerospace will also take responsibility for cross-programme production of the same set of structures for the PW1700G engine that will power the smaller Embraer 175-E2.
Manufacture of all the relevant components will be undertaken at GKN Aerospace’s facilities in Sweden, Norway and Connecticut. First delivery of development parts is scheduled to take place early in 2015.
