An Italian manufacturer, which houses a facility in Farmington, will supply airfoil products for commercial and military engines to East Hartford aeroparts manufacturer Pratt & Whitney over the next decade, the company announced Monday. Pietro Rosa TBM, which makes parts and components for gas-turbine engines, said it signed a 10-year agreement with Pratt & Whitney, a division of Farmington conglomerate United Technologies Corp., to support its F135, PW2000 and geared turbofan (GTF) engines. Peitro Rosa said the long-term agreement could extend to its facilities throughout the U.S. and Europe. The companies said the agreement allows Pietro Rosa to further its advanced engineering capabilities, hot forming, and machining and surface finishing technologies. “We have tremendous growth ahead, and suppliers like Pietro Rosa that sign up to our contractual governance, commitment to cost competitiveness and continuous improvement will continue to have opportunities to grow with us,” said Art Erikson, Pratt & Whitney’s executive director of strategic sourcing. In 2016, Pietro Rosa acquired Farmington-based New England Airfoil Products and invested more than $10 million in the facility. Meanwhile, the state Department of Economic and Community Development (DECD) provided a $3 million low-interest loan. Founded in 1887, Pietro Rosa has developed more than 1,500 products in 30 different materials, including special steels, titanium alloys and aluminum, among others.
