The cross-sectional area (A) in the context of a CFM LEAP (Leading Edge Aviation Propulsion) engine or any gas turbine engine in aircraft design typically refers to the area of the engine’s inlet or the section through which air enters the engine. The specific formula for calculating this area may vary depending on the engine’s design and geometry.
- A is the cross-sectional area (in square meters, m²).
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the air density in kilograms per cubic meter (kg/m³).
- V is the velocity of the engine (in meters per second, m/s).
