Summary

 
Object and purpose of research.This paper studies icebreaker propellers. The purpose of this work is to develop the procedure for determination of intense-cavitation margin for icebreaker propellers.
Subject matter and methodsThe procedure for determination of second-stage cavitation margin for icebreaker propellers is developed by means of physical experiment in the cavitation tunnel and in the cavitation tank.
Main results.The paper suggests a numerical parameter characterizing propeller resistance to second-stage cavitation, and also suggests a technique for uniting the test data obtained in the cavitation tunnel and in the cavitation tank. It was demonstrated that propellers are practicable to design for operation at the initial phase of second-stage cavitation
Conclusion.The paper concludes that model tests of icebreaker propellers in the cavitation tunnel and in the cavitation test tank are necessary to obtain a reliable estimate for their second-stage cavitation margin.
