Rolls-Royce has commenced groundbreaking work at NASA's Stennis Space Center in Mississippi to test a hydrogen-fuelled aircraft engine in partnership with UK airline easyJet and Tata Consultancy Services. The test stand at the space center will facilitate the demonstration of a Pearl 15 engine operating solely on hydrogen fuel. This initiative follows a successful jet engine test run on hydrogen conducted by Rolls-Royce and easyJet in 2022. The Pearl 15 engine, renowned for its cutting-edge technologies and utilized in the Bombardier Global 5500 and 6500 aircraft, can propel the planes to speeds of Mach 0.9 (690 mph). Rolls-Royce had previously tested a Pearl annular combustor using 100% hydrogen to confirm the viability of the fuel under conditions akin to maximum take-off thrust. Deborah Robinson, Director of Test & Experimental Engineering at Rolls-Royce, expressed enthusiasm for collaborating with easyJet and NASA to explore the potential of decarbonizing aviation through hydrogen. David Morgan, easyJet's Chief Operating Officer, hailed the rapid progress from design to full engine testing with 100% hydrogen, emphasizing the move towards their vision of deploying zero-carbon hydrogen-powered aircraft technology. John Bailey, Director of NASA Stennis, welcomed the partnership with Rolls-Royce for the groundbreaking test project, indicating a positive outlook towards the hydrogen advancements in the aerospace industry.
