The cross-sectional area of a turboshaft engine inlet in aircraft design is a fundamental parameter that determines the amount of air entering the engine, which is crucial for engine performance. The formula for cross-sectional area (A) can be defined as:
– A is the cross-sectional area (in square meters, m²).
– ṁ is the mass flow rate of air entering the engine (in kilograms per second, kg/s).
– ρ is the density of the air entering the engine (in kilograms per cubic meter, kg/m³).
– Vi is the velocity of the air entering the engine (in meters per second, m/s).
