The pitching moment coefficient (cm) is a dimensionless parameter used in aerodynamics to describe the pitching moment experienced by an object, such as an airfoil or aircraft, as it moves through a fluid (usually air). It is a measure of the aerodynamic force that tends to cause the object to rotate about its center of gravity.
Â
- mm is the pitching moment coefficient.
- M’ is the pitching moment acting on the object.
- q∞ is the freestream dynamic pressure of the fluid flow.Â
- c is the reference area for two-dimensional body
