Recently, British multinational manufacturer GKN Aerospace Engine Systems announced the expansion of its risk and revenue sharing partnership (RRSP) with American aerospace manufacturer Pratt & Whitney.3D printingTo strengthen cooperation.

Deepen cooperation and leverage strength
GKN Aerospace Engine System will utilize3D printing-Additive manufacturing technology develops and manufactures fan housing mounting rings and fan gaskets for the Pratt & Whitney PW1500G and PW1900G engines of the GTF series.According to GKN Aerospace Engine System,3D printingIt can greatly reduce the use of raw materials, reduce product life cycle energy costs, and help reduce carbon emissions.The Pratt & Whitney GTF engine series was put into use in 2016. Since then, the engine has achieved its promised fuel consumption reduction of 16% to 20%, and a significant reduction in carbon emissions and noise footprint.

As part of the GTF series, the PW1900G engine that powers Embraer’s E190-E2 aircraft and the PW1500G engine that powers the Airbus A220 aircraft will be included in the RRSP plan. In the plan, GKN Aerospace Engine Systems is responsible for the design and manufacture of turbine exhaust casing (TEC) and intermediate compressor casing (IMC), as well as the manufacture of the engine’s low pressure turbine (LPT) shaft.The deepening of cooperation has also strengthened GKN Aerospace Engine Systems’ investment level in these engine projects and its role as a long-term supplier of Pratt & Whitney engine components. In addition, GKN also provides Pratt & Whitney with components for Airbus A320neo series aircraft and Mitsubishi Regional Jet (MRJ).
In the RRSP plan, an additive manufacturing process used by GKN is to combine raw metal wire with a laser mounted on a robotic arm, and use metal wire laser metal deposition (LMD-w) to achieve metal3D printingprocess.Just this month, GKN also continued to strengthen its cooperation with the Oak Ridge National Laboratory (ORNL), and reached a $17.8 million agreement to commission ORNL to build a new additive manufacturing production unit for it
