Rolls-Royce Pearl 15 Marks Launch of New Engine Family

The Pearl 15 brings improved efficiency, reduced emissions and noise, and better performance within the same nacelle package as for the BR700 family.

The new Pearl 15 engines endured testing at the Rolls-Royce Center of Excellence for Business Aviation Engines. Testing included lighting strikes and water ingestion.

Rolls-Royce unveiled a new engine family for the large and very-long-range class of business aircraft with its first applications—the Bombardier Globals 5500 and 6500, in hand. Quietly in development for years, the Pearl builds on the venerable BR700 family that has powered the Global 5000 and 6000 as well as the Gulfstream G550 and G650.
