Pratt & Whitney to Use Additive Manufacturing for PurePower Engine Components

For the first time in the industry, additive manufacturing will be used to produce jet engine parts. Pratt & Whitney has been working with additive manufacturing since the 1980s. More than 100,000 prototype parts have already been produced using additive manufacturing over the past 25 years. Pratt & Whitney will use additive manufacturing to produce compressor stators and synch ring brackets for its production engines. Also called three-dimensional printing, additive manufacturing builds parts one layer at a time. Successive layers of material are laid down under computer control. The objects produced can be almost any size, shape or geometry.

Pratt & Whitney has been collaborating with the University of Connecticut to advance its additive manufacturing research and development. During testing, nearly 15 months in lead-time has been saved compared to conventional manufacturing. In addition, up to 50 percent weight reduction in a single part has been achieved. More than $4.5 million has been invested into Pratt & Whitney’s Additive Manufacturing Innovation Center. It is the first of its kind in the Northeast region.  Components on the PurePower engines will also be made using metal injection molding, electron beam melt, and laser powder bed fusion.

Pratt & Whitney’s PurePower engines are the next generation of jet engines. They offer double-digit improvements in fuel consumption, noise, environmental emission, and operating costs. There are currently two families of engines. There are the PW1000G, or geared turbofan, engines and the PW800 engine series which will be power large business jets.  It is the first ultrahigh-bypass-ratio turbofan engine. The PurePower engine core is a high-performance core built for the demand of high-cycle, short-haul operations.  Thrust capabilities in the series range from 10,000 to 40,000 pounds. Pratt & Whitney predict that operators could save $2 million per aircraft per year versus today’s best airplanes.
