Aero-structural dynamics of a flexible hub connection for load reduction on two-bladed wind turbines
Publikováno v:
Wind Energy. 20:521-535
In this study, an innovative concept for load reduction on the two-bladed Skywind 3.4 MW prototype is presented. The load reduction system consists of a flexible coupling between the hub mount, carrying the drive train components including the hub as
