MODEL ICEBREAKING EXPERIMENTS AND THEIR CORRELATION WITH FULL SCALE DATA

The mechanism of icebreaking is discussed and in particular the part played by broken pieces of ice sliding along the hull sides is mentioned. The techniques involved in producing an analog of the situation by means of models are described and it is shown how an appreciation of the deficiencies of the use of modified wax to represent the icefield, has led to the development of a new material which provided an encouraging degree of correlation with the results of full scale trials. The full scale trials are described in some detail. Methods of representing icebreaker performance data are discussed and a simple theory is derived to link model data with the full scale results.
