Turbine Export

Turbine objects can be exported as a QBlade project file (.qpr) or into the text based .trb format. When a turbine object is exported into the .trb format, the associated blade (.bld) file is automatically created. Furthermore, the structural definition files (if the turbine has a structural model) and the controller parameters are also auomatically placed into the folder structure See an exemplary .trb file below:
