UNDERWATER SITUATION ILLUMINATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC B63C11/48 B63G5/00 B63G6/00 

FIELD: marine equipment.

SUBSTANCE: group of inventions relates to marine engineering and is intended to illuminate underwater environment. Underwater environment lighting device is an underwater vehicle having an on-board guidance and heading guidance system, a flexible extended towed antenna for detecting underwater objects, device for determination of ice thickness and at least one subglacial radio buoys separated from underwater vehicle with ice melting device and storage device connected with onboard underwater vehicle control system. Underwater vehicle is additionally equipped with power compartment, engine and propulsor to provide necessary maneuverability, device for extending from the body of a flexible extended towed antenna and active means for searching and classifying detected underwater objects, including a front-view sonar and side-scan sonars and at least one detachable blast sound sources. To illuminate underwater environment as self-contained unmanned underwater vehicle self-propelled underwater vehicle is used, having energy compartment, engine, propulsor and device for extension of flexible extended towed antenna, if necessary for classification and search of underwater objects, its side sonar and detachable explosive sound sources are used. After performing the task and / or for transition to another region, the flexible extended towed antenna is withdrawn into the submarine vessel housing and is transferred to the assigned area at a predetermined rate, if lifting of underwater vehicle to board of carrier for various reasons is not possible, then submarine buoy is separated from submarine with flexible link connecting it with underwater vehicle. Buoy is lifted to the water surface or frozen to the lower edge of the ice and the hole is melted in the ice, the antenna is projected to the surface and coordinates of the underwater vehicle are transmitted to the control station. Underwater vehicle is withdrawn from water or from under ice by vehicle designed for this purpose and delivered to designated place.

EFFECT: enabling observation of the underwater environment at given depth horizons in ice-covered areas with the FETA, detecting maneuvering underwater objects therein and transmitting information thereon to a control station.
