The Mass Flow Rate of Bypass Air in aircraft design refers to the rate at which air bypasses the engine core in a turbofan engine.
It is typically calculated using the following formula:
- The Bypass Ratio is the ratio of the mass of air that bypasses the engine core to the mass of air that passes through the engine core. It is a dimensionless value.
- The Mass Flow Rate of Core Air is the rate at which air passes through the engine core and undergoes combustion, typically measured in kilograms per second (kg/s).
