Preliminary results of a series of model scale propeller experiments are presented. A large (0270mm) model of a highly skewed controllable pitch propeller was tested in both open water and ice covered water in the ice tank at the Institute for Marine Dynamics. Both the open water and ice experiments were done at four different pitch settings, each over a range of advance coefficient. The ice strength and the depth cut into the ice by the propeller were varied in the ice tests. The main aims of the experiments were to measure the effects of these variables on blade loads, in addition to their effects on shaft loads. Shaft loads were measured using conventional dynamometry. Loads on one blade were measured using a hubmounted blade dynamometer designed and built for these tests. The blade dynamometer is described and some preliminary shaft and blade load measurements are presented and discussed.
