.ppg file

Hi,

A .ppg file of a model scale windturbine was provided to me. I am trying to convert this into a .trb type of file, without any success. An airfoil database has been delivered along with it, with lift, drag and moment coefficients. Any inputs on this would be highly appreciated.

 

kind regards,

Emiel Navis

Hi Emiel,

I am not familiar with the .ppg format. That said, there is no built-in functionality to automatically convert turbines from this format.

If you have all the necessary aerodynamic and rotor geometry data, you have two options:

  1. Manually generate a .bld file – This file defines the aerodynamic properties of the rotor. You can create it by directly modifying the ASCII file.
  2. Use QBlade’s GUI – You can import airfoil geometries and polar data into QBlade and then generate the rotor object in the Rotor Design module.

Once you have created the rotor definition, you can proceed with generating the turbine definition (.trb file) using the same approach, either via ASCII modification or the GUI.

Best regards,

David
