Pratt & Whitney completes additively manufactured TJ150 engine tests
Pratt & Whitney, an RTX business, headquartered in East Hartford, Connecticut, USA, has announced the successful completion of demonstration testing for its additively manufactured TJ150 engine. The testing focused on validating material behaviour in an operational environment and demonstrating durability that aligned with mission requirements.
Nearly 60% of the TJ150 engine, by volume, was produced using Additive Manufacturing, including major static and rotating hardware.
“For expendable engines like the TJ150, where missions can last minutes or hours, simplifying the design and scaling production quickly is essential to meeting rising demand,” said Jill Albertelli, president of Military Engines at Pratt & Whitney. “Additive Manufacturing helps us move designs from concept to capability faster, and we are leveraging what we learned on the TJ150 to benefit other programs, including the Pratt & Whitney Valox™ engine family.”
Pratt & Whitney has made targeted investments to advance Additive Manufacturing for the TJ150, strengthening its long-term producibility and scalability strategy. To date, Pratt & Whitney has consolidated more than fifty individual hot-section components into a small number of additively manufactured parts and has successfully tested an additively manufactured rotating turbine wheel. Together, these efforts led to the recently tested TJ150 configuration.
