Calculate Cmcg of Airplane Method to Calculate the Moment Coefficient about the Center of Gravity Cm,cg of Airplane Model 

Aerospace



Moment Coefficient Cm,cg of Airplane In order to Calculate the Moment Coefficient about the Center of Gravity, Cm,cg of Airplane Model (wing body arrangement) being testing in a subsonic wind tunnel. 

We must first have the value at which the Lift is found to zero at geometric angle of attack, alpha
We must also have the Angle of Attack, AOA alpha value and the corresponding Lift Coefficient Cl at this AOA.
Furthermore, we must also have two additional alpha values and the corresponding Moment Coefficients about the center of gravity.
The center of gravity in terms of Mean aerodynamic chord c is then entered.


Now, the Aircraft design parameters are entered,
Performing the calculation, the following parameters are computed,
