Embodiment Construction

[0032] refer to figure 2 , the wind turbine 40 includes a tower 42 , a nacelle 14 disposed at the top of the tower 42 , and a rotor 46 operatively coupled to a generator (not shown) housed within the nacelle 44 . In addition to the generator, the nacelle 44 houses various components required to convert wind energy into electrical energy and various components required to operate, control, and optimize the performance of the wind turbine 40 . The tower 42 supports the loads provided by the nacelle 44, the rotor 46, and other components of the wind turbine 40 contained within the nacelle 44, and also operates to lift the nacelle 44 and rotor 46 to a height above ground or sea level, at Faster moving airflow with low turbulence may often be found at this height.

[0033] The rotor 46 of the wind turbine 40 (shown as a horizontal axis wind turbine) serves as a prime mover for the electromechanical system. Winds above the minimum level will activate the rotor 46, causing rotation...

Abstract

A connecting joint for attaching a wind turbine blade to a rotor hub includes an insert configured to be coupled to the wind turbine blade. The insert includes a main body having an outer surface configured to interface with the blade; a first tubular extension extending from the main body and having inner and outer surfaces configured to interface with the blade; and a second tubular extension extending away from the main body and having inner and outer surfaces configured to interface with the blade. A wind turbine blade having such a connecting joint is also disclosed. Additionally, a method of making a wind turbine blade including the connecting joint is disclosed.

Description

technical field [0001] The present invention relates generally to wind turbines, and more particularly to an improved joint for connecting a wind turbine rotor blade to a rotor hub, and a method of forming a wind turbine rotor blade having an improved joint connecting the wind turbine blade to the rotor hub. Background technique [0002] Wind turbines are used to generate electricity from renewable resources and without burning fossil fuels. Typically, wind turbines convert kinetic energy from the wind into electricity. A horizontal axis wind turbine includes a tower, a nacelle at the top of the tower, and a rotor having a central hub and a plurality of blades connected to and extending outwardly from the hub. The rotor is supported on a shaft extending from the nacelle, the shaft being operatively coupled, directly or indirectly, with a generator housed within the nacelle. Thus, the generator produces electricity when the wind forces the blades to rotate. [0003] In rec...
