Rolls-Royce recently announced the launch of a new engine family for business aviation with the introduction of the Pearl, a purpose-built unit that will be the sole engine for Bombardier’s latest business jets — the Global 5500 and the Global 6500.
The Pearl engine combines technologies derived from Rolls-Royce’s Advance
2 technology demonstrator programmes with proven features from its BR700, a leading engine family in business aviation.
The Pearl 15 will deliver up to 15,125lb of thrust; and despite delivering up to 9% more thrust during take-off than the BR700, the engine will be 2dB quieter — and operators will benefit from a 7% improvement in specific fuel consumption.
The engine will also deliver the lowest NOx emissions for engines in this class, despite being able to power aircraft at speeds approaching the speed of sound (Mach 0.90).
Chris Cholerton, president of Civil Aerospace at Rolls-Royce, said: “Our teams have worked hard behind the scenes to develop this new engine, which is a pioneering product, bringing together the most eco-friendly and efficient technologies available today.”
The Pearl 15 also features a new-generation Engine Health Monitoring System that introduces advanced vibration detection; it also 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.
