MATHEMATICAL MODELING OF THE ACOUSTIC FIELD OF A WIND TURBINE PROPELLER

A method for calculating the acoustic propeller of a wind turbine has been created based on the mathematical model proposed by L.Ya.Gutin for calculating the noise of an aircraft propeller.In the calculation, the main source of noise is the propeller, therefore other noise sources are not taken into account.All calculations were made in the Mathcad 15 program and acoustic field directivity graphs were constructed.A graph of the dependence of sound pressure in the far acoustic field was constructed.
