The cross-sectional area of ribs in aircraft design refers to the area of the rib structure when viewed from a specific direction. In the context of an aircraft wing, for example, it is the area of the rib exposed when looking at the wing’s cross-section. This measurement is essential for determining structural integrity and aerodynamic characteristics. The SI unit for cross-sectional area is typically 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).
- A is the cross-sectional area of Ribs (in square meters, m²).
- V is the velocity of the Ribs (in meters per second, m/s).
