Abstract
This paper deals with effects of geometric non-linearities on the aeroelastic stability of a steady-state defl ected blade.
Today, wind turbine blades are long and slender structures that can have a considerable steady-state defl ection which
affects the dynamic behaviour of the blade. The fl apwise blade defl ection causes the edgewise blade motion to couple
to torsional blade motion and thereby to the aerodynamics through the angle of attack. The analysis shows that in the
worst case for this particular blade, the edgewise damping can be decreased by half. Copyright © 2010 John Wiley &
