Summary

 
Propeller of the shallow-water icebreaker (wide blades, blade area ratio EAR = 0.87) is designed to ensure power efficiency and second step cavitation prevention at bollard pull. Modified sharp profile is applied to reduce ice loads acting on propeller and propulsion complex as well as to ensure main electric engine operability. Based on the updated CNIIMF procedure for structural design of ice-breaking propellers, this study determines global and local ice loads on propeller blades, calculates their stress-strain state and assigns the scantlings for wide-blade propeller so as to ensure fatigue and static strength (including edges and peripheric sections).
