Rolls-Royce has completed ground testing for its Pearl 10X engine and commenced production at its Dahlewitz, Germany facility. The new engine, designed for the Dassault Falcon 10X, marks a significant milestone for manufacturers and operators within the business aviation supply chain.
Why it matters
By leveraging 90% commonality with existing Pearl engines, the Pearl 10X is engineered to streamline maintenance and reduce the complexity of managing mixed-model aircraft fleets for business operators. The integration of 3D-printed components aims to improve turbine durability and operational efficiency through better thermal management.
The Pearl 10X engine produces over 18,000 lb. of thrust and has achieved 250 flight hours through mid-October 2026. This development follows a rigorous program of 5,000 hours of ground testing.
The players
Rolls-Royce
A global aerospace manufacturer specializing in high-performance power systems for civil and defense aviation.
Dassault
An aircraft manufacturer that produces business jets, including the Falcon 10X line.
The details
Rolls-Royce integrates 3D-printed tiles into the engine combustor to maintain uniform temperatures, which decreases nitrous oxide emissions and extends turbine blade life. The company maintains a dedicated support site near the Dassault final assembly line in Bordeaux-Merignac to facilitate flight testing. The engine is designed for high commonality, sharing 90% of its architecture with the broader Pearl engine family, which facilitates parts inventory and technician training.
Timeline
June 2026: Falcon 10X flight-test campaign began.
Mid-October 2026: Pearl 10X engine reached 250 total flight hours.
Market Landscape
The Pearl 10X follows the design and reliability precedents established by the Pearl engine family currently in service. This program continues the industry trend of increasing component commonality to reduce the operational burden for fleet operators.
Fleet operators should evaluate how the 90% commonality of the Pearl 10X aligns with their current inventory of parts and maintenance protocols for other Pearl-powered aircraft. Monitoring this engine's performance benchmarks against the established service life of existing models is advised for long-term fleet planning.
The takeaway
The transition to 3D-printed combustor tiles offers a tangible improvement in turbine maintenance intervals that operators should watch for in future fleet upgrades. Asset managers should track the upcoming certification milestone as a key signal for final procurement and service entry planning.
