Experimental Study on the Influence of Water and Cavitation on Propeller Load during Ice-Propeller Milling

When the ice-class propeller sails in an icy sea, it is affected by external factors such as water, ice, and cavitation, process of mutual interference extremely complicated. In order to study influence water cavitation on load during ice-propeller milling process, a test platform for ice–water action was constructed. The single blade were measured air (atmospheric pressure decompression conditions). Simultaneously, changes bearing force studied at different working conditions. results show that, milling, direction thrust generated opposite that axial ice; combined two causes loss, whereas ice increases torque. presence thrust, torque, fluctuating amplitude blade. occurrence reduces torque amplitudes while decreasing tangential
