What Does BPR Stand For?

BPR stands for Bypass Ratio

Bypass Ratio (BPR) is a key performance metric in aerospace engineering, particularly for turbofan engines. It is defined as the ratio of the mass of air that bypasses the engine core to the mass of air that passes through the core. A higher BPR indicates more efficient engines, as it typically results in greater thrust generated at lower fuel consumption, enhancing overall performance and reducing environmental impact. BPR is an essential factor in the design and optimization of modern aircraft propulsion systems.
