British engineering giant Rolls-Royce marked a significant milestone on April 3rd, 2024, with the successful inaugural flight test of its latest creation, the Pearl 10X engine. This powerful engine, designed specifically for business jets, took to the skies mounted on a Boeing 747 flying testbed in Tucson, Arizona.

The Pearl 10X represents the newest member of Rolls-Royce's renowned Pearl engine family. Significantly, it also marks the first time a Rolls-Royce engine will power a Dassault business jet. Dassault Aviation, the esteemed French aircraft manufacturer, has chosen the Pearl 10X to exclusively power its brand-new flagship aircraft, the Falcon 10X.
This inaugural flight test signifies a critical stage in the Pearl 10X program's development. The engine has already undergone extensive ground testing, accumulating over 2,300 hours on both the Advance 2 demonstrator and the Pearl 10X configuration itself. The positive outcome of the flight test paves the way for further in-air evaluations in the coming months. The Pearl 10X boasts impressive specifications. Its efficient core and low-pressure system combine to generate over 18,000 pounds of thrust. Furthermore, the engine promises a 5% improvement in efficiency compared to previous Rolls-Royce business aviation engines, while also achieving superior noise and emission performance. This translates to a powerful engine that prioritizes both performance and environmental responsibility.
This successful flight test is a major win for Rolls-Royce as it solidifies its position as a leader in the business jet engine market. The Pearl 10X's combination of power, efficiency, and environmental consciousness positions it as a compelling option for Dassault's Falcon 10X and potentially other future business jets. The coming months of flight testing will provide valuable data to further refine the engine and ensure its seamless integration with the Falcon 10X airframe.
