Pratt & Whitney, a subsidiary of RTX, has introduced new advancements in the maintenance of its PW1000G aircraft engine family. The company announced a novel additive repair process using 3D printing, which will significantly cut maintenance processing time by over 60%. The technology, developed by Pratt & Whitney’s North American Technology Accelerator in Jupiter, Florida, utilizes a method called 'Directed Energy Disposition.' This innovation is expected to help recover $100 million worth of parts in the next five years once fully scaled and applied globally.
Kevin Kirkpatrick, the Vice President of Aftermarket Operations at Pratt & Whitney, commented on the benefits: “By eliminating several steps in the current repair method, this new technology reduces overall process time by more than 60%, with the greatest benefits via minimization of machine changeover and reduced heat treat cycles.” He further noted its potential impact on reducing supply dependency and exploring more repair opportunities.
In related developments, Pratt & Whitney has signed an agreement with Delta TechOps to expand the GTF engines' overhaul capacity at facilities near Hartsfield-Jackson Atlanta International Airport. This step will allow Delta Air Lines’ maintenance arm to overhaul up to 450 engines annually, reinforcing its status within the GTF MRO network.
