Warm Model Ice and Propeller Interaction, Capturing the Driving Mechanics
In the drive to design robust and more efficient propellers, the need to understand propeller-ice interaction is increasing. Traditionally MARIN has built up this kind of propeller design knowledge by developing and testing large systematic propeller series, such as the classic Wageningen B-series and the recent C- and D-series. With systematic variations of blade number, area, pitch and profiles it can be investigated how these parameters influence the design and how the most efficient designs for operation in open water and in ice can be reached. This is becoming especially important for the lower ice class propellers, which are rarely sailing in ice covered areas. Apart from this, these designs should be optimized for low noise emission as well, to ensure application in the sensitive Arctic environment. When both milling and crushing loads can be captured using a warm model ice, the testing of such a large systematic propeller series becomes possible without the use of an ice basin.
