Problems solved by technology

However, the fasteners used in such bolted or pinned joint designs are typically heavy, adding significantly to the overall weight of the rotor blade
Also, mechanical fasteners are often metal components, which increases the likelihood of lightning strikes

Abstract

A rotor blade assembly for a wind turbine may include a first blade segment having a first joint end and a second blade segment having a second joint end, with the blade segments being coupled together such that the first and second joint ends are located at or adjacent to a joint interface between the blade segments. The blade assembly may also include a pre-loaded beam extending outwardly from the second blade segment across the joint interface such that the pre-loaded beam is received within the first blade segment. The pre-loaded beam may be compressed between the opposed internal structural components of the first blade segment such that a first engagement interface is defined between a first side of the pre-loaded beam and the first internal structural component and a second engagement interface is defined between an opposed second side of the pre-loaded beam and the second internal structural component.

Description

technical field [0001] The present subject matter relates generally to rotor blades for wind turbines, and more particularly to improved joint configurations for segmented wind turbine rotor blades that include contact or engagement positioned between portions defined in blade segments One or more preloaded joint components at the interface. Background technique [0002] Wind power is considered to be one of the cleanest and most environmentally friendly energy sources currently available, and as such, wind turbines are receiving increasing attention. A modern wind turbine typically includes a tower, generator, gearbox, nacelle and a rotor having a rotatable hub with one or more rotor blades. The rotor blades capture the kinetic energy of the wind using known airfoil principles. The rotor blades transmit kinetic energy in the form of rotational energy to turn a shaft that couples the rotor blades to a gearbox (or directly to a generator if a gearbox is not used). The gene...
