compute_alpha_zero_lift(alpha_deg: ndarray, Cl: ndarray, linear_eps: float = 0.001) → float

Computes the zero-lift angle of attack for an input set of angles of attack and lift coefficients. If no linear regime is detected, None is returned.

Parameters:

• alpha_deg (numpy.ndarray) – One-dimensional array of angle of attack in degrees.

• Cl (numpy.ndarray) – One-dimensional array of lift coefficients, one-to-one mapping with alpha_deg

• linear_eps (float) – Tolerance used to determine whether a linear regime is present in the range of angles of attack provided as input. Default: 0.001

Returns:

The zero-lift angle of attack in degrees if the linear regime is detected, otherwise None

Return type:

float or None
