BOTTOM OF THE GLIDE AMPHIBIAN Russian patent published in 2021 - IPC B60F3/00 B63B1/18 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and is intended for use mainly in conditions of movement both on water and on land. The bottom of the glide amphibious vehicle contains an external elastic closed contour, the upper deck part of which is located above the static waterline, and the other part is sliding on water or land and is lined with a wear-resistant elastic material with the formation of sides, an internal cavity formed by an external elastic closed contour containing buoyancy-promoting air, along the height of which there are air-containing layers of different stiffness. The lining with an elastic wear-resistant material is made in the form of sheets, which have bends for the formation of the sides. The inner cavity is formed by an external elastic closed contour and is filled in height with layers of air-containing elastic porous material with closed pores glued together. Among them there are lower and upper layers, the density of which is higher, and the air content in which is less than in one or more layers of material located between them. The upper layer has a thrust against a lattice frame made of rolled metal, to which the bends of sheets of elastic wear-resistant material are fixed.

EFFECT: improvement in the operational properties of the amphibious vehicle is achieved.
