Ice impact loads on blades of cycloidal propellers
Abstract Cycloidal propellers, also known as vertical axis propellers, have so far seen limited use in ice-covered waters. However, as these kind of propulsors are becoming more common with new manufactures emerging, the ice loads on propeller blades also becomes an important topic.
