Aerospace



Neutral Point Location of Airplane In order to Calculate the Neutral Point Location of Airplane Model 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 we have the Neutral Point Location hn of the Airplane. The following formula for Neutral Point Location hn is used in the calculation,
hn = hac(wb) + Vh(at/a)(1depsilon/dalpha)
