The concept of using wind turbine propellers in the construction of acoustic screens as an example of a circular economy model

This paper aims to conceptualise the construction of noise barrier panels from components recovered from used wind turbine propellers. At present, they are mainly waste, but many ideas for their reuse are emerging. Based on previously conducted material tests, the strength of the panels was calculated in accordance with EN 14388. The finite element method and the ANSYS space-claim programme were used to analyse the strength and generate a 3D numerical model of the cracked wind turbine propeller panels. The permissible values given in the standard were compared with those obtained for the deflection of the component.
