Triumph Group's Geared Solutions business has been selected by Piasecki Aircraft Corporation (PiAC) to design and build a prototype main transmission for PiAC's hydrogen-powered PA-890 eVTOL compound helicopter. This project will begin this summer at Triumph Geared Solutions in Park City, Utah.

“Through innovative development of the main transmission for the next generation of sustainably fuelled aircraft, our team of experienced design engineers will collaborate with Piasecki to support the breakthrough PA-890 aircraft,” says Pete Gibson, president of Triumph Geared Solutions. “This prototype will incorporate additive technology advancements and Triumph's agile and flexible approach to the design process.”

“We selected the Triumph Geared Solutions team for this project based on its extensive experience in gearbox design, development, and its ability to implement innovative manufacturing approaches,” adds John Piasecki, president and CEO of PiAC. “Triumph's collaborative approach to development was a critical factor in our selection of it to jointly develop a main transmission prototype for the PA-890's hydrogen electric propulsion system.”
