AbstractPropeller/ice interaction experiments were conducted at the Institute for Marine Dynamics as part of a Joint Research Project Arrangement(JRPA #6) with Finland. Contact loads as well as non-contact interaction loads were measured. Non-contact loads are defined as the loads on the propeller blades due to interruption of the hydrodynamic flow by an ice block which is in the proximity position to the propeller. During the non-contact experiments two pressure sensors which were mounted in the propeller blade at radius 0.8R were used to determine the hydrodynamic pressures on the back of the blade. These experimental measurements were compared to results from a two-dimensional theoretical evaluation of the pressure distribution for the same propeller and ice conditions. The direct boundary element method was used to solve the theoretical problem.
