bladex.blade.Blade.export_ppg

Blade.export_ppg(filename='data_out.ppg', D_prop=0.25, D_hub=0.075, n_blades=5, params_normalized=False)

Export the generated blade parameters and sectional profiles into .ppg format.

Parameters:

• filename (string) – name of the exported file. Default is ‘data/data_out.ppg’
• D_prop (float) – propeller diameter
• D_hub (float) – hub diameter
• n_blades (float) – number of blades
• params_normalized (bool) – since the standard .ppg format contains the blade parameters in the normalized form, therefore the user needs to inform whether the provided parameters (from the class Blade) are normalized or not. By default the argument is set to False, which assumes the user provides the blade parameters in their actual values, i.e. not normalized, hence a normalization operation needs to be applied so as to follow the .ppg standard format.
