... technology Propulsion systems The trend of higher bypass ratios (BPRs) on civil turbofan engines is likely to continue, and it seems plausible that the future turbofan engines will have BPR values as high as 15 [ 1 ]. This implies that the future high BPR engines will employ a larger fan, hence...
