Japanese firm Mitsubishi Heavy Industries is to develop and manufacture structures for the Pratt & Whitney PW1200G geared turbofan, to be used on the Mitsubishi Regional Jet.
MHI states that it will build combustors, high-pressure turbine discs and diffuser cases for the powerplant.
Under the agreement signed with Pratt & Whitney it will also perform final engine assembly and operational testing at its Nagoya Guidance & Propulsion Systems facility in Komaki City.
MHI says P&W has already delivered development examples of the diffuser cases and combustors for the PW1200G to this facility.
"Arrangements for the tooling and equipment for the final assembly and operational testing procedures have been completed, and the engine test cell has been modified as necessary," it adds.
"Because final assembly must conform with P&W's technical demands, pertaining to the forms of all engine parts, the Nagoya plant is currently co-ordinating with P&W to develop the required final assembly management system."
MHI has previously taken part in work for the PW1100G powerplant, a sister engine designed for the Airbus A320neo.
