SYSTEM FOR CHANGING BUOYANCY AND TRIM OF UNMANNED UNDERWATER VEHICLE WITH AUTOMATIC CONTROL Russian patent published in 2020 - IPC B63G8/26 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of underwater shipbuilding, in particular to the buoyancy control and submarine differentiation systems. System for changing buoyancy and trimming of underwater technical means comprises two independent equalizing trim tanks for intake of outboard water, high-pressure electric pumps, pipelines with shutoff valves, automatic control unit with remote control. Equalizing trim tanks function as equalizing and trim tanks. Equalizing trim tanks are not connected with compartments in which are located, and are made with allowance for pressure increase due to compression of air inside and placement in compressed air space of other system elements. Pressure in cisterns varies in proportion to their degree of filling, which makes it possible to determine, to what extent tank is filled, through determination of pressure taking into account corrections for change of temperature and humidity of air.

EFFECT: change of trimming trim and expansion of its functionality is achieved.
