Abstract:

The aim of the present study was to predict propeller performance during propeller-ice interaction. Total loads acting on a propeller blade during propeller-ice interaction were assumed to consist of three major components: separable hydrodynamic loads, inseparable hydrodynamic loads, and ice milling loads. A panel method and an empirical formula were used for the hydrodynamic load calculations and the ice contact load calculations, respectively. This empirical model was implemented into a numerical panel code. The numerical prediction model for the ice loads including the detailed implementation is described, and the results are compared with experimental results.
