LONDON— Rolls-Royce has completed all certification testing for its latest business jet engine, the Pearl 10X, marking a major step toward approval from the European Union Aviation Safety Agency (EASA).
The company is now preparing to submit final reports to the regulator as it continues to support Dassault Aviation’s Falcon 10X development program. The Pearl 10X, the newest and most powerful member of Rolls-Royce’s Pearl family, has been designed exclusively for the Falcon 10X.
Rolls-Royce Pearl 10X Test Campaign
The Pearl 10X underwent an extensive testing program that included both ground-based and airborne evaluations aboard Rolls-Royce’s retired Boeing 747-200 testbed.
These trials covered endurance, performance, and environmental assessments under a variety of operating conditions.
According to Rolls-Royce, the testing phase confirmed the maturity and reliability of the engine’s design. The company says the results demonstrate that the Pearl 10X meets all technical and safety requirements ahead of certification.
With testing now finished, Rolls-Royce’s engineering teams are focused on compiling and submitting detailed performance data for regulatory review.
Focus Shifts to Certification
The next stage involves EASA’s thorough evaluation of Rolls-Royce’s data package. Certification review ensures that the Pearl 10X complies with all applicable airworthiness, emissions, and safety standards.
Rolls-Royce has not specified when approval will be granted, but maintains that the program remains on track to support Dassault’s flight-test timeline for the Falcon 10X.
Dassault has not yet announced a first-flight date for the Falcon 10X, but its first prototype is already in final assembly.
The French manufacturer aims to enter the large-cabin jet segment with an aircraft capable of rivaling Gulfstream’s G700 and Bombardier’s Global 8000, with the Pearl 10X providing the power needed for long-range performance.
Engine Power and Support Network
While Rolls-Royce has not disclosed the Pearl 10X’s exact thrust rating, it will exceed the 18,250 pounds of thrust produced by the Pearl 700 that powers the Gulfstream G700 and G800.
To support the program, Rolls-Royce has opened a customer service center in Mérignac, near Bordeaux, close to Dassault’s final assembly site. The facility will provide maintenance and technical support for the Pearl 10X once operational service begins.
The Pearl engine family has become central to Rolls-Royce’s business aviation success. The Pearl 15, which powers Bombardier’s Global 5500 and 6500, has logged over 280,000 flight hours with a 99.95% reliability rate.
The newer Pearl 700 is in active service, with over 70 engines already powering aircraft worldwide.
Bottom Line
The completion of certification testing for the Rolls-Royce Pearl 10X represents a key milestone for both Rolls-Royce and Dassault Aviation.
With final validation now underway, the Pearl 10X moves closer to powering the Falcon 10X’s first flight.
Once certified, it will become the most advanced and powerful engine in the Pearl series, further strengthening Rolls-Royce’s position in the competitive business jet engine market.
