Problems solved by technology

However, it is difficult or time-consuming to fabricate certain parts of the rotor blade shell, such as the spar flange, core and / or root support, so that they can adequately support the rotor blade shell and be made into the intended aerodynamic due to, for example, local variations in the dimensions of the individual layers, in the composition of the resin, in the curvature of the individual layers, and / or in the tension exerted on the shell during its manufacture

Embodiment Construction

[0013] As applied herein, the term "vane" is used to denote any device that provides a reaction force when moved relative to the surrounding fluid. As applied herein, the term "wind turbine" is used to denote any device capable of generating rotational energy (quantity) from wind energy, more precisely converting the kinetic energy of wind into mechanical energy. As applied herein, the term "wind generator" is used to refer to any wind turbine that generates electrical energy from rotational energy generated by wind, and more precisely converts mechanical energy converted from kinetic energy of wind into electrical energy. As applied herein, the term "windmill" is used to denote any wind turbine that utilizes the rotational energy produced by the wind, but more precisely converts the kinetic energy of the wind into mechanical energy for an intended purpose other than electricity generation, such as, But not limited to: pumping fluids and / or grinding objects.

Abstract

A method for fabricating a blade using a mold having a shape corresponding to a predetermined finished shape of at least a portion of the blade. The method includes stacking a plurality of layers of a material in the mold, stacking at least one component with the stack of the plurality of layers, wherein the component is a composite comprising a cured resin and at least one layer of fiber, and laminating the stack of the plurality of layers and the component.

Description

technical field [0001] The present invention relates generally to blades useful as wind turbine rotor blades, and more particularly to methods and apparatus for making blades. Background technique [0002] Typically, wind turbines contain a rotor with a plurality of blades. The rotor is mounted on a frame or within the engine nacelle, which is arranged on top of a truss or tubular tower. Utility grade wind turbines (ie, wind turbines designed to provide electrical power to a utility grid) have large rotors (eg, 30 meters in diameter or larger). Blades on these rotors convert wind energy into torque or force that drives one or more electrical generators, which are usually, but not always, rotationally coupled to the rotor through a gearbox. The gearbox boosts the inherently low rotational speed of the turbine rotor to efficiently convert mechanical energy into electrical energy, which is fed into the utility grid. Gearless direct drive turbines also exist. [0003] At lea...
