moment coefficient

moment coefficient

[′mō·mənt ‚kō·i′fish·ənt]
(aerospace engineering)
The coefficients used for moment are similar to coefficients of lift, drag, and thrust, and are likewise dimensionless; however, these must include a characteristic length, in addition to the area; the span is used for rolling or yawing moment, and the chord is used for pitching moment.
