Abstract

With the increase in popularity of podded propulsors and arctic navigation, understanding
the interaction between a podded propulsor and ice has become more important.
Propeller-ice interaction itself is a complicated process with a high level of uncertainty
resulting from the uncertainties associated with the properties of the ice and with the
propeller-ice interaction conditions. Model tests provide relatively well-controlled ice
properties and interaction conditions to reduce the uncertainties. In order to improve the
understanding of this interaction and to develop numerical models of it, a model podded
propulsor was used in “Puller” mode, and ice loads were measured on its instrumented
blade and propeller shaft. The results of the experiments conducted to simulate the
interactions (milling) of the instrumented blade with ice in different operating conditions
are reported in this paper. Loads measured during the milling consist of ice milling loads,
“inseparable” hydrodynamic loads, and “separable” hydrodynamic loads. The sample
results presented here include ice milling and inseparable hydrodynamic loads for various
advance coefficients and depths of cut (amount of blade penetration into ice). Some
results are compared with existing ice load models.
