airfoilprep.Polar.unsteadyparam

Polar.unsteadyparam(alpha_linear_min=-5, alpha_linear_max=5)

compute unsteady aero parameters used in AeroDyn input file

Parameters :

alpha_linear_min : float, optional (deg)

angle of attack where linear portion of lift curve slope begins

alpha_linear_max : float, optional (deg)

angle of attack where linear portion of lift curve slope ends

Returns :

aerodynParam : tuple of floats

(control setting, stall angle, alpha for 0 cn, cn slope, cn at stall+, cn at stall-, alpha for min CD, min(CD))
