Rolls-Royce is progressing towards the inaugural flight of its Pearl 10X engine aboard a Boeing 747-200 flying testbed, following the successful completion of rigorous ground tests. These tests have verified the engine’s reliability and performance metrics, aligning with the company’s predictions. Engineered for the Dassault Falcon 10X, the Pearl 10X is distinguished as the most potent engine in its family, delivering 18,250 lb. of thrust.
The comprehensive ground testing phase covered evaluations focusing on the turbofan’s reduced emissions, its innovatively manufactured combustor, and a novel accessory gearbox designed to facilitate enhanced power extraction. Notably, the engine achieved its maiden run earlier this year, equipped with a full powerplant setup including the Spirit AeroSystems nacelle and engine build-ups, where it exceeded expected thrust levels from the outset.
Dassault Aviation’s Falcon 10X, revealed in May 2021, is poised for a 2025 service debut, marking a significant milestone in aviation luxury and performance. The Pearl engine family, beyond its application in the Falcon 10X, is the chosen powerplant for ultra-long-range jets from Bombardier and Gulfstream. Currently, the Pearl 15 powers Bombardier’s Global 5500 and 6500 models, whereas the Pearl 700 is set to propel the upcoming Gulfstream G700 and G800 models, expected to enter service later this year.
Introduced in 2019, the Pearl 700 is part of Rolls-Royce’s strategic Advance2 demonstrator program. It boasts an 8% increase in take-off thrust and a 5% reduction in fuel consumption compared to its predecessor, the BR725, underscoring Rolls-Royce’s commitment to innovation and efficiency in the aerospace sector.
