A MODEL STUDY OF ICEBREAKER OPERATIONS

Describes a study using an icebreaker made of wood in a modified Wind-Class design, secured to a constant-thrust dynamometer and toward an ice simulator (brass cylinder). Upon impact, the resulting loads were recorded by a force-measuring dynamometer. Although the brass cylinder does not behave dynamically or statically like an ice sheet and the vertical force measurements cannot be related to ice thickness, the measurements can be related to icebreaker performance if the model behaves in a manner similar to its prototype. Dimensional analysis for similitude is presented. A simple mathematical model of I.V. Vinogradov, No. 18724, is used and provides useful information on the vertical component of force.
