초록

A rotor blade for a horizontal axis wind turbine wherein a multiplicity of sucker rods are utilized internally of the blade root for securing the blade to the rotating hub of the turbine including the method of attaching the blade root to the hub and the method of making the blade root.

대표청구항 ▼

A rotor blade for a wind turbine having a formed blade portion and a blade root, said root being formed for attachment to the hub of the rotational shaft of the turbine, said blade root including at least one sucker rod secured internally thereof and disposed for securement to said hub, said sucker rod being unbonded to said blade root for a substantial portion of the length thereof forming a free end of said sucker rod of the root end and a secured end at the formed blade portion end, said sucker rod being formed shorter in length at the root end than said rotor blade root whereby the free end of the sucker rod is recessed in the surrounding structure of the root of said rotor blade so that it can be placed in tension when it is secured to said hub. A method for making a wind turbine rotor blade having a blade root which is secured to the hub of the rotational shaft of the turbine comprising embedding a multiplicity of sucker rods internally around the periphery of said blade root generally parallel the axis of said blade, coating a substantial length of the sucker rod from the root end with a releasing agent, and bonding the remaining length of the sucker rod internally to said blade root whereby the root ends of said sucker rods are approximately equal length free ends floating in the root of said blade.
