METHOD OF OPTIMIZING A ROTOR BLADE, ROTOR BLADE AND WIND TURBINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240011463 titled 'METHOD OF OPTIMIZING A ROTOR BLADE, ROTOR BLADE AND WIND TURBINE

Simplified Explanation

The patent application describes a method for optimizing the design of a rotor blade for a wind turbine. The rotor blade extends from a coupling to a tip in a longitudinal direction and has an aerodynamic profile between a leading edge and a trailing edge. The method involves designing the rotor blade for specific environmental conditions, including air density, and incorporating a sound-protection means in the external region of the blade. The air density at the installation site is compared to the design air density, and if the air density is lower, the induction factor is increased by upsizing the sound-protection means.

  • The method optimizes the design of a rotor blade for a wind turbine.
  • The design includes a sound-protection means in the external region of the blade.
  • The air density at the installation site is compared to the design air density.
  • If the air density is lower, the induction factor is increased by upsizing the sound-protection means.

Potential applications of this technology:

  • Wind turbine industry: This method can be applied to optimize the design of rotor blades for wind turbines, improving their efficiency and performance in different environmental conditions.

Problems solved by this technology:

  • Inconsistent environmental conditions: By designing the rotor blade for specific environmental conditions and adjusting the sound-protection means based on the actual air density at the installation site, the method ensures optimal performance of the wind turbine.

Benefits of this technology:

  • Improved efficiency: Optimizing the rotor blade design based on environmental conditions allows for better utilization of wind energy, resulting in increased energy production.
  • Enhanced durability: Incorporating a sound-protection means in the external region of the blade helps protect the rotor blade from potential damage caused by environmental factors, such as noise and vibrations.


Original Abstract Submitted

a method of optimizing a rotor blade of a wind turbine as well as to an associated rotor blade, and to a wind turbine, wherein the rotor blade extends from a rotor-blade coupling to a rotor-blade tip in a rotor-blade longitudinal direction with a rotor-blade length, having an aerodynamical profile extending between a leading edge and a trailing edge, wherein the method comprises the following steps: designing the rotor blade for design environmental conditions including at least one design air density, with the designing comprising providing a sound-protection means within a blade external region of the rotor blade, the latter being defined as the 50% of the rotor-blade length abutting the rotor-blade tip; providing an air density at the installation site of the wind turbine; comparing the air density with the design air density; and increasing the induction factor by upsizing the sound-protection means in case the air density is lower than the design air density.
