Abstract
The application of shallow-angled skins with off-axis fiber angle less than 45 degrees, increases the bending stiffness and strength of the large-Scale wind turbine blade but reduces its torsional stiffnesses, making it susceptible to the classical flutter instability problem. Single-blade quasi-steady eigenvalue analyses using HAWCStab2 were performed to evaluate the flutter performance of a 5 MW pitch-regulated wind turbine blade with shallow-angled skins configurations. The results showed that the application of shallow-angled skin design concept to the 5 MW blade model does not pose the flutter instability problem. (C) 2015 Elsevier Ltd. All rights reserved.
