Rolls-Royce (Booth X98) reports that its Pearl 10X engine is on track to begin flight trials on the company’s Tucson-based Boeing 747 testbed later this year. The engine—which is destined for Dassault’s forthcoming Falcon 10X—delivers more than 18,000 pounds of thrust and is compatible with 100 percent sustainable aviation fuel operation. It is the first time a Rolls-Royce product has been selected to power a Falcon business jet.

At the heart of the Pearl 10X is Rolls-Royce’s Advance2 core, which combines with technology developed for the current-generation Pearl engines to create a highly efficient powerplant that will push the Falcon 10X to near-sonic speeds. The powerplant incorporates a high-efficiency blisk fan, compressor with six blisk stages offering a market-leading pressure ratio, two-stage shroudless high-pressure turbine, and four-stage low-pressure turbine.
