Abstract

Abstract: Polar propellers working in frozen waters would suffer the threaten of ice loads. However, the complex shape of the blade brings difficulties to the correlation analysis of the propeller-ice contacting phenomena and ice loads. This paper utilized a three-dimensional wing structure to simplify the propeller blade shape to a certain extent. The three-dimensional wing was constructed by selecting a foil profile at 0.75R of a certain PC3 level ice-class propeller (IACS, 2016) and extended the profile in the spanwise direction. Then a propeller-ice contacting model and a wing-ice contacting model were established based on the state-based peridynamics theory. The established models are verified by the model tests results. The hydrofoil shape-controlling parameters, including the attack angle, the thickness distribution, and the bow distribution of the hydrofoil were further studied in the research to investigate their effects on the propeller-ice contacting proceedings.
