Blade's structure

Hello, I just started using FAST to find the aerodynamic loads, then I will do a dynamic analysis in SAP2000. However, I am trying to find any details of the structure thickness of the airfoil and how it is changing along the blade. Could you provide me any data? Thank you in advance.

Best regards,
George Panagiotou

Hi George,

I think the following links could be useful to you.

I don’t believe that the NREL 5 MW turbine blade properties are based on manufactured blades, but are representative of a typical blade that length. The Sandia report presents a blade structure that was created to match the existing blade properties. The forum topic covers a similar discussion.

Hope this help,
Kieran

Thank you very much Kieran for your quick response!
