SOFT STEPPED FLOAT Russian patent published in 2012 - IPC B60V1/08 B64C35/00 

FIELD: airfoil boat engineering, aircraft engineering and shipbuilding.

SUBSTANCE: invention refers to airfoil boat engineering, aircraft engineering and shipbuilding, it deals with shaping of soft stepped floats designed predominantly for airfloat boats. The soft stepped float has a pneumoshell equipped with connecting elements to attach it to the vehicle body, predominantly an airfloat boat, and at least three pneumocylinders placed in the pneumoshell. Each of the pneumocylinders is equipped with a gas filler. At least one of the pneumocylinders is situated lower than the others and is made with a smaller length. Each of the pneymocylinders is placed in the pneumoshell. The pneumoshells are connected to each other, and at the head they are connected to each other with the help of a cowl. The cowl that connects the pneumoshells to each other at their heads contains a bed element for the heads of the pneumoshells.

EFFECT: increase in the aerodynamic lift due to the fact that the hull angle is expanding in the course of gliding.
