Rgarding AoA- different wnd sped-along same section in blade

Hi all
I have run NREL Phase VI for 7, 10 and 15 m/s. I have compared the pressure cofficients at 30%, 63% and 95%.
When I presented the relative velocity magnitude. I got following doubt.
At 30% or 63% or anyother sections along the blade span at different speeds, AoA will remain the same or it will change as the inlet velocity is changed.

Dear Ijaz,

The AoA varies with wind speed, induction, rotor speed, and flexible blade motion.
