Rolls-Royce Pearl 10X engine reaches 1,000 test hours

The newest member of the Pearl engine family, the Pearl 10X, has continued making development progress, accumulating more than 1,000 testing hours. The first Pearl 10X test engine ran earlier this year, surpassing target thrust levels on the first test run. Powering Dassault Aviation's flagship Falcon 10X business jet, the Pearl 10X marks the first Rolls-Royce engine to power an aircraft of the French aircraft manufacturer. RELATED: Dassault Falcon 10X is one step closer to entering serviceSo far, the development program has included the testing of the new ultra-low emissions ALM combustor, which is compatible with 100% sustainable aviation fuel (SAF) and the new accessory gearbox, which allows for higher additional power extraction. One of the next milestones will be the first full powerplant, including its Spirit nacelle, EBU and mount system, entering the test program later this year. "Our Pearl 10X team is extremely focused on the development of the engine and it makes me proud to see the continuous progress of the program," said Dr. Dirk Geisinger, Director of Business Aviation at Rolls-Royce. "The combination of a highly-efficient power and outstanding environmental performance of the Pearl 10X is in a class of its own and will support Dassault's Falcon 10X in setting new standards in the ultra-long-range corporate jet market." The Pearl 10X engine features the Advance2 engine core, combining it with a high-performance low-pressure system, resulting in a thrust of more than 18,000 lbf. Compared to the last generation of Rolls-Royce engines, the Pearl 10X is 5% more efficient while still offering low noise and emissions performance.
