It is known that the primary means to break the ice cover is the icebreaker fleet. However, large energy consumption for the destruction of the ice, the inability to perform icebreaking operations in shallow waters because of the high rainfall of icebreakers and other forces to search for fundamentally new ways razruneniya ice. One is developed by the author issledovaniyrezonansny method of destruction of ice cover.

 

It is known that the motion of a load of ice cover in ice and water in developing a system of flexural-gravity waves (IIV), ie combination of flexural vibrations of the ice plate and associated gravitational waves of water. When the velocity of the load close to the minimum phase velocity of IIV, the water ceases to maintain the ice sheet, the balance is achieved only by the elastic properties of ice, the amplitude of IIV increase sharply and with a sufficient quantity of ice loads destruction begins with the power consumption by several times (depending on thickness ) compared with icebreakers and ice-breaking attachments. This rate is called resonance, and the method itself is such a destruction of the ice has been called a resonance.

 

Resonance method of destruction of ice cover can be any vehicle capable of traveling on ice cover with sufficient speed and creating sufficient load. There have been cases of destruction of ice from IIV moving cars, trains on the railway crossings, during takeoff and landing aircraft, etc. However, at present the most appropriate means for implementation of the method are amphibious hovercraft (AEP)

 

The advantages of MRA are the lack of exposure their korpusaso ice, cross over the snow-ice cover, traffic safety over the broken ice and open water. The virtual absence of rainfall in AEP can break the ice in pools of any depth.

 

Using the SVP for destruction ice desirable because this type of vehicle possible combination of transport and ice, we'll get functions, and their all-terrain qualities that make them possible year-round operation.

 

The high speed of ice breaking SVP allows efficient produ-dit early opening of individual sections of rivers and reservoirs. This may not only increase the period of navigation, but also prevent the phenomenon of mash. Work SVP in the resonant regime effectively affects not only the surface but deep ice that can prevent disasters occurring during freeze-up and break-up.

 

The work of scientists obtained experimental and theoretical dependence of disclosing all the possibility of his method.
