calculate_performance_parameters_from_polar(aero_data: dict) → dict[source]#

Computes performance parameters, such as \(\alpha_{ZL}\), \((L/D)_\text{max}\), etc. from a set of MPOLAR data.

Parameters:

aero_data (dict) – Aerodynamic data output by run_mpolar or calculate_aero_data with alfa_array != None

Returns:

Dictionary containing a set of performance parameters for the airfoil system. The outputs vary depending on the input aerodynamic data, since the range of angles of attack covered may not allow for accurate estimates of some of the outputs. Outputs may include:

  • "alf_ZL": Zero-lift angle of attack (degrees)

  • "LD_max": Estimate of maximum lift-to-drag ratio

  • "alf_LD_max": Angle of attack (degrees) that gives the maximum lift-to-drag ratio

Return type:

dict
