The moment coefficient about the leading edge (c) is a dimensionless parameter used in aerodynamics to describe the aerodynamic moment or torque acting on an airfoil or wing about its leading edge. It provides a normalized measure of the rotational force that causes the airfoil to pitch or rotate around its leading edge due to aerodynamic forces.
- is the moment coefficient about the leading edge.
- is the moment about the leading edge (in N·m).
- is the dynamic pressure of the freestream flow (in N/m^2).
- is the chord length of the airfoil (in m)
