Abstract
Presented herein are the results of an exploratory study on the applicability of chaos theory to continuous-mode icebreaking by a model-scale POLAR-class icebreaker hull towed in a laboratory ice tank. Chaos theory pertains to chaoticdynamic systems. Such systems are nonlinear and deterministic, and are very sensitive to initial conditions such that they give outputs which standard frequency analysis techniques indicate to be indistinguishable from a stochastic process. Further, their phase-space trajectories are characterizable as being contained in a strange attractor of fractal dimension. Temporal records of resistance and hull motions of the towed hull, under several test conditions, were analyzed to show that continuous-mode icebreaking by a model-scale hull, in fact, comprises a chaotic-dynamic system with a strange attractor having a dimension (in phase-space) between 4 to 5, for the conditions tested. The implications of this result for modeling and understanding of continuous-mode icebreaking are discussed.
