### Stability and Control Estimating Aerodynamic Properties

1 Estimate measure is better the trailing edge angle where is the thickness to chord ratio of the airfoil Note that this estimate can be off by 300 2 Then calculate the theoretical 2D liftcurve slope 3 Modify the value in 2 to account for Reynolds number Re106 Re107 4 Calculate the final 2D liftcurve slope
