| Description: | CRREL Report Abstract: Results of propulsion tests in level ice on a model of the WTGB 140-ft Great Lakes icebreaker are presented and compared to available full-scale data. In spite of the difficulties in exactly modeling full-scale conditions, the predictions based on the model test results of the ship performance compared reasonably well to those measured during full-scale trials. Several possible sources of errors are identified. In particular, duplication at the model scale of the ship hull's ice friction coefficient is considered to be critical in determining the ice resistance and the corresponding propulsion characteristics, namely propeller speed, thrust and torque. |
