0

Rolls-Royce’s Pearl 15 engine has received its official certification by the Federal Aviation Administration.

The engine, which was developed at the Rolls-Royce Centre of Excellence for Business Aviation engines in Dahlewitz, Germany, has previously been certified by the European Union Aviation Safety Agency and Transport Canada Civil Aviation.

The Pearl 15 was custom-designed to power Bombardier’s Global 5500 and Global 6500 aircraft. Dirk Geisinger, director of business aviation, Rolls-Royce, said, “We have worked closely with the teams at the Federal Aviation Administration and Bombardier to achieve this certification and would like to thank them for their support.

“Our production and services teams are fully focussed on delivering a smooth entry into service and the planned production ramp up.”

The Pearl engine uses technologies derived from the Rolls-Royce Advance2 technology demonstrator programmes and from the BR700, the company’s legacy engine for business aviation.  It also uses Rolls-Royce’s Engine Health Monitoring System that detects advanced vibration detection, remote engine diagnostics and bi-directional communications.

The Pearl 15 has the same nacelle envelope as the BR700 but is more powerful, with a maximum certified thrust of 15,250 lbs, 7% better specific fuel consumption,  2dB cumulative quieter and a 20%  improvement in NOx emissions margin.
