The cross-sectional area of the jet engine’s inlet in aircraft design represents the area through which air enters the engine. It’s a critical parameter for engine performance analysis. The formula to calculate the cross-sectional area (A_inlet) is as follows:
- A = Cross-sectional area of the jet engine’s inlet (in square meters, m²)
- ṁ = Mass flow rate of the jet engine (in kilograms per second, kg/s)
- ρ = Density of the air ingested by the engine (in kilograms per cubic meter, kg/m³
- V = Inlet velocity of the air (in meters per second, m/s)
