Capability of Aerodyn in considering balde flap

Postby Mahdi.Hatamzadeh » Mon Jun 10, 2019 8:41 am

Hi

I want to know if the Aerodyn have the capability of adding any flap to the blades?
I want to investigate the effects of adding flap to the blades in wind turbines. So please help me in this case.

thanks.

Dear Mahdi,

Are you referring to the flapwise bending of the blade or a trailing edge flap for aerodynamic control?

Hi
I'm studying on the effects of adding a trailing edge flap to wind turbine blades on reduction of induced dynamic loads.

Dear Mahdi,

The ability to actively control trailing-edge flaps has never been a fully supported feature of FAST / OpenFAST. There has been discussion on this forum regarding using existing features of FAST plus customized enhancements to model actively controlled trailing-edge flaps, e.g. see: viewtopic.php?f=2&t=1014&p=7268. Moreover, a recent pull request into OpenFAST (not yet merged into OpenFAST dev) should allow this capability to be fully supported in a future version, see: https://github.com/OpenFAST/openfast/pull/213.
