Preliminary Results of DD-963 Model Tests in Broken Ice Fields
1990
Thomas, III, William L. | Bishop, Richard C. | Devine, Edward A.
This report presents the preliminary results of tow basin tests conducted with a model of the DD963 in fields of simulated broken ice cover representing conditions found in the Marginal Ice Zone (MIZ). Model tests were also performed in conditions representing broken ice in a confined ice channel which has been prepared for passage by an icebreaker. The test program was directed toward the definition of speed limits as a function of ice concentration for non-interference of ice floes with the sonar dome, bilge keels, propellers, and rudders. Recommendations for future model tests are discussed.
