  • Wind turbine design method
    Patent number: 11566598
    Abstract: A radiating component of the wind turbine is modelled as a plurality of elements, wherein each element represents a physical portion of the radiating component and at least a portion of each of the elements are acoustically coupled to one or more of the other elements. A simulation of a vibrational source located within the wind turbine is applied at an interface of the modelled radiating component. A transfer function is used to determine the transmission of vibrations from an interface with the vibrational source to the elements. Tonal noise radiated from the elements to an environment external to the wind turbine is determined based upon the transmission of vibrations from the interface through the elements. The design of the radiating component, or of a component between the radiating component and the vibrational source, is modified to reduce the tonal noise radiated from the radiating component.
