Abstract

A rotor blade assembly for a wind turbine is disclosed. The rotor blade assembly includes a rotor blade having surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a tip and a root. The surfaces further define an interior, and the rotor blade further defines a span and a chord. The rotor blade assembly further includes a strut disposed in the interior and extending between the pressure side and the suction side. A length of the strut extends in a generally spanwise direction, and a width of the strut extends diagonally to the chord.

Description

technical field [0001] The present invention relates generally to rotor blade assemblies, and more particularly to rotor blade assemblies having internal structures designed to reduce buckling. Background technique [0002] Wind energy is considered to be one of the cleanest and most environmentally friendly energy sources available, and wind turbines have gained a lot of attention in this regard. A modern wind turbine typically consists of a tower, generator, gearbox, nacelle and one or more rotor blades. The rotor blades use known airfoil theory to capture the kinetic energy of the wind. The rotor blades transmit kinetic energy in the form of rotational energy to turn a shaft that connects the rotor blades to a gearbox or, if a gearbox is not used, directly to the generator. The generator then converts the mechanical energy into electrical energy, which is fed into the utility grid. [0003] The specific size of the fan rotor blades is an important factor affecting the ...
