Analysis on the particularity of propulsor of ice-going ships
[Objectives] The propulsor is the source of propulsion during the ship's navigation, and its design is also a key part of the ship's design process. Due to the different working conditions, propulsors of ice-going ships differ greatly from propulsors of open water vessels in terms of load...
