Embodiment Construction

[0110] Embodiments described herein include a wind turbine that includes at least one rotor blade having an airfoil shape along the entire length of the rotor blade to facilitate increasing the annual power generation of the wind turbine. More specifically, the rotor blades described herein include a structural support assembly positioned within the rotor blade cavity, the structural support assembly being coupled to the wind turbine pitch bearing to facilitate having an airfoil shape at or near the hub of the wind turbine The root part of the rotor blade.

[0111] As used herein, the term "vane" is intended to represent any device that provides a reaction force when in motion relative to a surrounding fluid. As used herein, the term "wind turbine" is intended to represent any device that generates electrical power from rotational energy, and more specifically, converts kinetic energy of wind into mechanical energy and vice versa. As used herein, the term "annual production" ...

Abstract

The present invention relates to a rotor blade for use with a wind turbine and a method for assembling the same. A rotor blade (22,100,200,300) for use with a wind turbine (10) is provided. The rotor blade includes a blade sidewall (110,304) at least partially defining a cavity (114,147,160,210,312) extending from a blade root (24,102,218) towards a blade tip (26,104,220) of the rotor blade, the blade sidewall having a leading edge (120) and a trailing edge (122), a structural support assembly (124,324) at least partially positioned within the cavity and extending from the blade root towards the blade tip, the structural support assembly having a root end (126,204) and an opposing tip end (128,206), and at least one support member (134,148,150,172,174,212,326,328) coupled between the blade sidewall and the structural support assembly.

Description

technical field [0001] The subject matter described herein relates generally to wind turbines, and, more specifically, to rotor blades for use with wind turbines. Background technique [0002] At least some known wind turbine rotor blades include two blade shell sections made of fiber-reinforced polymer. The blade shell parts are molded and then joined together along cooperating edges using a suitable bonding material. The blade shell part typically comprises a panel wall made using suitable, evenly distributed fibers, fiber bundles or fiber mats laminated in a mold part. However, the panels are relatively light and have only low stiffness. Consequently, the toughness and stiffness and the bending strength of the plate walls cannot withstand the loads and forces exerted on the rotor blades during operation. To increase the strength of the rotor blade, the blade shell part is reinforced with spar caps laminated to the inner surface of the blade shell part. At least some k...
