Аннотация: In the Research Institute of Mechanics of MSU proposed new type of wave propellers, which use the energy of breaking waves to propel vessel. As a model of such propeller we consider interaction of the incoming waves with immersed inclined rigid plate, which can move in horizontal direction perpendicular to the inclination axis and fixed in all other degrees of freedom. By lab and numerical tests there is shown presence of the effect of plate motion against waves. Average velocity of such motion for given wave properties is non-monotonically dependent on the plate immersion depth, inclination and the plate length. Two-dimensional non-stationary calculations were performed in XFlowTM package to simulate lab conditions. It was shown that with channel depth increase mean velocity is decreased. Glissade effect is discovered and studied: the plate when partially taken out of the water is speed up to definite constant velocity and moves in the direction of the waves above physically non-disturbed water surface. Numerically was shown independence of the average plate velocity on the plate mass. Lab and numerical test are in good agreement with each other.
