Rolls-Royce reported it delivered the first sets of Pearl® 15 production standard engines to Bombardier, which has fitted the power units into its new Global 6500 business jet.
The Pearl series of twin-shaft turbofan engines based on the previous BR700 series co-developed by Rolls Royce with BMW through their past joint venture. The Pearl 15 is the exclusive engine choice for Bombardier’s Global 5500 and 6500 aircraft, and was designed and optimized in partnership with Bombardier. The aircraft and engine were introduced in May 2018.
Rolls-Royce began developing the Pearl engine earlier, applying for EU Air Safety Administration certification in 2015. It made its first ground run that year, type tests in 2016 and flight tests in 2017.
According to Rolls-Royce, the Pearl combines technologies derived from its Advance2 technology demonstrator programs with features from the BR700 family. The Pearl 15 has the same nacelle envelope as the BR710, but is more powerful (maximum certified thrust of 15,250 lbs.); offers up to 7% lower specific fuel consumption; is 2 dB quieter; and shows a 20% improvement in NOx emissions margin.
“We are now looking forward to supporting Bombardier as they prepare for the aircraft to enter into service later this year,” according to Dr. Dirk Geisinger, Rolls-Royce director – Business Aviation.
The Bombardier Global 6500 will debut later this year. It’s a 17-passenger jet with a maximum range of 6,600 nautical miles and a top speed of 0.90 Mach.
