The cross-sectional area of core air in an aircraft engine, denoted as “A_core,” represents the area through which air flows in the core components of the engine. It is a crucial parameter for understanding the airflow and performance of the engine’s core section.
The formula for calculating the cross-sectional area of core air is:
– A is the cross-sectional area of core air (in square meters, m²).
– ṁ is the mass flow rate of core air (in kilograms per second, kg/s).
– ρ is the density of core air (in kilograms per cubic meter, kg/m³).
– V is the velocity of core air (in meters per second, m/s).
