Selection and Analysis of Parameters in Model Test of Ice Breaking by Air Cushion Vehicle

In order to validate the theory and select effective operational parameters in practical ice-breaking by air cushion vehicle (ACV), experimental study should be carried on firstly. The relationships of corresponding parameters between ACV model and prototype and between the ice-like material and the real ice are established on the basis of the similarity theory and the differential equation of thin elastic vibrating plate under static or moving load. According to geometric and dynamic similarity between model and prototype, for the conditions of different water depth, ice thickness, mass and velocity of ACV in actual operating mode, the pressure and velocity of ACV model, the elastic modulus and density of ice-like material in model test can be determined, the method of extending the model test results to prototype is proposed.
