Object and purpose of research. The purpose of this study is to review the developments and present new results obtained by Krylov State Research Centre (KSRC) in design of propellers for carrier ships with high ice classes. Materials and methods. The results were obtained by means of experiments and calculations. Main results. The study presents main results of KSRC developments intended to obtain more accurate strength parameters and increase propulsion performance of ice-class propellers (including ice operation at bollard pull in the vicinity of cavitation condition), as well as to combat partial cavitation on propeller blades in open-water transit conditions. Conclusion. The progress in large Arctic carrier ships aroused new requirements to their propulsor, and the results and technologies available with KSRC make it possible to satisfy these requirements and, at the same time, keep KSRC-developed propellers of high ice classes competitive and commercially attractive.
