The axial force coefficient (CA) is a dimensionless quantity used in aerodynamics to describe the axial force acting on a body, such as an airfoil or wing, due to the fluid flow. It is one of the force coefficients used to understand the aerodynamic behavior of bodies in fluid flows.
- CA = Axial force coefficient
- A = Actual axial force acting on the body
- q∞ = Freestream dynamic pressure (a measure of the kinetic energy of the fluid flow)
- S = Reference area of the body
