UNDERWATER VEHICLE OF GLIDING TYPE Russian patent published in 2021 - IPC B63G8/24 

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding, namely to autonomous uninhabited underwater self-propelled vehicles for the study of water areas. The underwater vehicle of the gliding type contains a body made in the form of an ellipsoid of rotation. In this case, the body is made in the form of an ellipsoid of rotation with the formation of a permeable part, equipped with a strong body and a buoyancy control system located in it, consisting of hydraulic cylinders, controlled valves, variable volume receivers, pistons with rods, and hydraulic pumps of the working fluid. Moreover, the buoyancy control system is divided into independently operating executive paths located symmetrically relatively to the vertical axis of the underwater vehicle of the gliding type. The piston rods can have a different length in the permeable part and, accordingly, a different volume for the displacement of the point of application of the resultant force of excessive buoyancy relatively to the vertical axis of the underwater vehicle of the gliding type with the possibility of rolling and, accordingly, maneuvering the underwater vehicle of the gliding type in depth and course.

EFFECT: increased maneuverability characteristics of the underwater vehicle is achieved when changing the depth and course, and increase in its reliability and survivability.
