METHOD FOR DETECTING UNDERWATER OBJECTS UNDER ICE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC B63G5/00 B63G6/00 

FIELD: machine building.

SUBSTANCE: invention relates to the field of marine engineering and can be used to search for underwater objects under ice. Device for searching underwater objects under the ice, comprising a body with a parachute fixed therein, intended for gliding the device, a battery, a transmitter, a receiver, memory device, antenna, autotrack mechanism, control unit, clock mechanism, cable-cable with hydrophones and/or hydroacoustic emitters fixed on it. Massive cone-shaped nozzle is installed in the head part of the body, connected to the vessels by flow channels, having openings for discharge of their contents to the outside, as well as the attachment of the nozzle to the body and separation from it. In order to search for underwater objects under ice, an apparatus for searching underwater objects under ice is delivered to the search area of an underwater facility using an aircraft. Provide the device for searching underwater objects under the ice a positive stabilizing aerodynamic moment due to the installation of the stabilizer and the massive head part. Head part is made with a pointed conical shape and is equipped with a metal rod, which pierces the upper layer of ice. Hole is melted in the ice, into which, as the ice melts, the body of the device is dipped to search underwater objects under the ice, until it is fixed by the stabilizer tail of the stabilizer about the edge of the hole. Detach the head part with the cable-cable attached to it and, using it as a sinker, deepen the hydrophones and / or hydroacoustic emitters to a given depression.

EFFECT: it is possible to observe the underwater environment and to ensure the stealthiness of observation during operation of the device in the mode of noise guidance.
