Rolls-Royce Pearl 15 is a business-aviation turbofan developed exclusively for the Bombardier Global 5500 and Global 6500. It combines established BR700 features with technologies from the Advance2 demonstrator programmes. Its new core includes a ten-stage high-pressure compressor and a two-stage high-pressure turbine, while an enhanced three-stage low-pressure turbine supplies fan power. Engine vibration health monitoring supports maintenance planning. Rolls-Royce lists a 15,125 lbf thrust rating, a 43:1 overall pressure ratio and a 4.8:1 bypass ratio.
