The moment coefficient about the trailing edge (c) is a dimensionless parameter used in aerodynamics to quantify the aerodynamic moment or torque acting on an airfoil or wing about its trailing edge. This coefficient provides a normalized measure of the rotational force that causes the airfoil to pitch or rotate around the trailing edge due to aerodynamic forces.
- is the moment coefficient about the trailing edge.
- is the lift coefficient, which quantifies the lift generated by the airfoil.
- is the moment coefficient about the quarter-chord point.
