Observing and testing device for icing process of marine air propeller

The invention belongs to the field of ship and ocean engineering, and particularly relates to an observing and testing device for icing process of a marine air propeller. The device provided by the invention is simple in structural design and operation method, and can obtain the influence of main environmental factors of icing on the icing rate of the blade through the icing simulation test of theair propeller rotating under specific air and snow conditions, and the relevant test data can verify the accuracy of numerical simulation to further optimize the numerical model. The device providedby the invention can explore the influence of the material, structural parameters and the like of the propeller on the amount of ice on the blade by changing the material, structural parameters and the like to provide reference for the material selection and structural design of the air propeller blade, and can also control the conditions such as a splash droplet diameter and a propeller rotationspeed to change the icing t
