The coefficient of moment, also known as the pitching moment coefficient, is a dimensionless quantity that measures the tendency of an aerodynamic force to cause a body to rotate about its center of gravity
- Cmcgwh: Coefficient of moment about the center of gravity due to the weight (gravity) force.
- Clw: Lift coefficient due to the weight (gravity) force.
- αw: Angle of attack at which the lift coefficient is calculated.
- iw: Angle of inclination (angle of the weight vector) relative to the aircraft’s longitudinal axis.
- Cdw: Coefficient of drag due to the weight (gravity) force.
- Zcgw: Vertical distance between the center of gravity and the reference point for moment calculations (often measured downward).
- c: Mean aerodynamic chord length.
