The mass flow rate of an afterburner Turbofan in aircraft design is related to the additional fuel injected into the exhaust stream to increase thrust. The mass flow rate of the afterburner (ṁ_ab) can be calculated using the following formula:
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the air density in kilograms per cubic meter (kg/m³).
- A is the cross-sectional area Afterburner Turbofan (in square meters, m²).
- V is the velocity of the Afterburner Turbofan (in meters per second, m/s
