EBACE 2018: Rolls-Royce launches Pearl engine

The new engine family will power Bombardier’s latest ultra-long-range business jets, the Global 5500 and Global 6500.

Rolls-Royce has launched the Pearl, a new engine family that will be the sole powerplant for Bombardier’s latest ultra-long-range business jets, the Global 5500 and Global 6500.

The Pearl engine will integrate technologies derived from the company's Advance2 technology demonstrator programmes, along with proven features from the Rolls-Royce BR700.

First to market will be the Pearl 15 which will deliver up to 15,125lb of thrust (ISA +15), thanks to a new, highly efficient engine core. Despite delivering up to 9% more thrust during take-off than the BR700, the engine will be 2 decibels quieter and operators will benefit from a 7% improvement in specific fuel consumption (SFC).

According to Rolls-Royce, the engine will also be designed to deliver world-leading emissions performance, including best in class NOx emissions.

The new engine, which has been developed at Rolls-Royce’s Centre of Excellence for Business Aviation engines in Dahlewitz, Germany, has undergone a comprehensive test programme and received EASA certification on 28th February. The engine is currently undergoing flight tests at Bombardier’s Flight Test Centre in Wichita, Kansas, supporting the planned entry into service at the end of 2019.

The UK engine maker says the Pearl 15 will exemplify the company's IntelligentEngine vision of a future where product and service become indistinguishable thanks to advancements in digital capability. As well as a new-generation Engine Health Monitoring System that introduces advanced vibration detection, the engine benefits from the incorporation of advanced remote engine diagnostics and bi-directional communications that allow for easy remote reconfiguration of engine-monitoring features from the ground.
