In flight mechanics, the coefficient of the moment of the center of gravity (CG) is a parameter that helps to describe the rotational behavior or stability of an aircraft. It’s often denoted as Cmcgp and represents the moment (torque) created around a specific axis due to the displacement of the aircraft’s center of gravity from a reference point.
Cmcgp = Mcgp / (0.5 * ρ * V^2 * S * c)
- Mcgp: Moment around the center of gravity due to the displacement of the CG.
- ρ (rho): Density of the fluid (e.g., air) through which the aircraft is flying.
- V: Velocity of the aircraft relative to the fluid.
- S: Reference area, often related to the wing area.
- c: Chord length of the wing or another relevant geometric parameter.
