Abstract
This paper demonstrates the application bined analytical/FEA coupled aero-structure
simulation in design of bend-twist adaptive blades. A ic algorithm based design tool, in which
the power curve is predicted through bined coupled aero-structure simulation, has been
developed. A bend-twist adaptive blade has been designed to be used on the rotor of a constant speed
stall regulated wind turbine. The bend-twist adaptive blade is assumed to be made out of anisotropic
composite materials. The designed blade has the same aerofoil and chord distribution as the original
blade used on the wind turbine, but with a different pre-twist distribution. The simulated results show
a significant improvement in the average power of the studied stall regulated wind turbine when
employing the designed adaptive blades.
