RING INSERT FOR A WIND TURBINE ROTOR BLADE

摘要

The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having a blade root section and a rigid ring insert. The rotor blade has pressure and suction sides extending between leading and trailing edges. The blade root section includes an end face configured to attach the rotor blade assembly to a hub. Further, the blade root section includes a span-wise end portion defined by inner and outer circumferential components separated by a radial gap. The radial gap includes a first laminate material embedded between the inner and outer circumferential components at a first span-wise depth and a second laminate material embedded between the inner and outer circumferential components at a second span-wise depth. Thus, the rigid ring insert is disposed in the radial gap and embedded between the first and second laminate materials.
