Ice Floe Trajectory Under the Action of Propeller Pumping

In order to study the influence of propeller pumping action on ice trajectory during the process of ice propeller interference, this paper built a motion trajectory measurement platform based on circulating water tank, combining high-speed camera and the Photron FASTCAM Analysis (PFA) method, and tested and analyzed the trajectory of ice at different propeller rotation speeds. After systematic analysis of the test results, it is found that when the propeller rotates at a high speed and the flow velocity is small, the pumping action effect is obvious, which apparently changes the model ice trajectory and even makes the ice and propeller collide. When the model ice volume is large and the water flow velocity is fast, the propeller pumping action effect is small, and it is difficult for the pumping action effect to change the ice trajectory because of the influence of the water flow velocity, which has little effect on the model ice motion trajectory.
