Rolls-Royce’s Pearl 10X engine—selected by Dassault for the forthcoming Falcon 10X—has now passed the 2,000-hour milestone in ground-testing. Rated at more than 18,000 pounds of thrust, the engine met its thrust objectives on its first run and testing has run smoothly to date.

The first flight trials engine has been delivered from Rolls-Royce's Dahlewitz factory near Berlin to L3Harris in Waco, Texas, for installation on the company’s Boeing 747 testbed, with a first flight expected before the end of the year. Flight trials will be conducted at Rolls-Royce's test site in Tucson, Arizona.
