FIELD: transportation.
SUBSTANCE: method for destructing the ice cover by a vessel in a compressed air flow is proposed and done by excitation of resonant bending-gravity waves in the ice when the vessel moves. Simultaneously with the translational movement of the vessel an additional load is applied to ice, which is directed downwards and forming a gas-dynamic jet from the high pressure impeller, the nozzle of which is located below the bottom of the hull at an angle in a vertical plane to the longitudinal axis of the vessel and perpendicular to the horizontal, from fastened movable horizontal partitions on the axis of rotation, located in the forebody and after body of the vessel through the simultaneous fore-and-aft balance of the vessel by the stern. The high-pressure jet is sufficient to create maximum fore-and-aft balance of the vessel by the stern, resulting from the pressure of the gas-dynamic jet at a given height of opening of movable horizontal partitions that create aerodynamic lift capacity on the forebody of the vessel.
EFFECT: invention helps to increase the efficiency of ice cover destruction.
