Synthetic Ice with various compressive strength for Propeller-Ice interaction test has been studied. Compressive strength, about 1.0∼20kg/cm^2 of synthetic ice prepared from NaCl+CMC aqueous solution was required. The production process of synthetic saline ice with large thickness in short time has been carriedout. The synthetic ice were availably used for Propeller-Ice interaction test and satisfactory experimental results has been obtained. This report mainly describes details of production process and mechanical properties of the synthetic saline ice to be used in the model ice load test for arctic marine propeller.
