Rolls-Royce conducted flight trials of its Pearl 10X on the company's 747-200 flying testbed in Tucson, Arizona.

Celebrating the 9,000th engine produced at its Dahlewitz site, Rolls-Royce continued to progress on its newest engine model, the Pearl 10X, accruing 3,400 test hours in the program.

Slated for Dassault Aviation’s ultra-long-range Falcon 10X, the Pearl namesake has successfully completed all but one major engine certification test, Rolls-Royce reported. These have included initial maintenance interval, type test, medium bird strike, outdoor crosswind, and emissions. Remaining trials are scheduled in the coming months in support of Dassault's upcoming Falcon 10X flight-test campaign.
