Experimental Study of Possibility of Submarine Vessels Emerging in the Compact Ice at a Limited Depth of Water Area

摘要

Traditionally submarine vessels (SV) emerging from under ice cover performing by static loading of ice from below through the creation of positive buoyancy by main ballast tanks. However thickness of ice (approximately 1 meter) from under which modern submarine vessel can emerge essentially limits the use of traditional method, particularly during submarine vessels motion in the severe ice conditions of Arctic region. For breaking the ice cover of greater thickness can be used flexural gravity waves (FGW) caused by the submarine vessel motion with certain critical speed near the bottom ice. It is known that in the coastal areas water depth is often less than 100 meters. This paper presents experimental study of influence of water depth on the deflection and the length of flexural gravity waves.
