This term represents the total surface area of the airframe’s cross-section, which is perpendicular to the aircraft’s longitudinal axis. It includes the area encompassed by the aircraft’s fuselage, wings, tail, and other structural components. The cross-sectional area is a key parameter used in aerodynamic calculations, drag analysis, and structural design.
- 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 through which Airframe Design (in square meters, m²).
- V is the velocity of the Airframe Design (in meters per second, m/s).
