Deflection of the blade

Hello everyone,

I am looking forward to understand the methodology used by FAST_AD to calculate the deflection of the blade.

As far as I understand the inputs are the stiffnesses of different sections of the blade and the mode shapes (two for flatwise and one for edgewise).

But what are the actual equations used to calculate the deflection of the tip?

Thank you,

Best regards.

Dear Ohiana,

Please see the forum topic found here for a description of the blade model in FAST and links to where you can find more information: Coupled blade modes in FAST.
