Summary

 
Object and purpose of research. This paper discusses laboratory measurements of cavitation-induced noise of propeller models in uniform flow, as well as extrapolation of the model test data to the full scale
Subject matter and methodsThe study is based on the model test data obtained in the cavitation tunnel for the models in uniform flow, as well as on extrapolation of these data to the non-uniform flow behind the hull, taking into account the laws of cavitation-induced noise simulation.
Main results. This study made it possible to develop a prediction method for spectral levels of cavitation-induced noise radiated by the propeller, based on the model test data obtained in the cavitation tunnel, as well as to develop the method of model test data extrapolation to the non-uniform flow behind the hull.
Conclusion. results could be used to predict cavitation-induced noise of marine propellers at detailed design stage.
