Design consideration of two candidate propellers for ice breaking vessel
The propellers for ships operating in the Antarctic and Arctic regions encounter fragments of ice and sometimes are damaged according to the severity of ice load. The design of propellers for such ships is quite different from that of conventional ships, since in designing the propeller geometry, no...
