LV14948B - Flying sonar-buoy device - Google Patents

Abstract

The purpose of invention is to increase the determination efficiency of object coordinates under water that is achieved by location of searching sonar (5) in unmanned aerial vehicle (1) equipped with a winch (4) for lowering or lifting sonar antennas, system (2) for flight and sonar operation control, as well as with communication system including the radio transmitter (3) for data transmission from sonar buoy. The unmanned aerial vehicle (1) is launched from ships, aircraft or shore with its task to reflect rapidly the underwater situation.

Description

Description of the Invention

The invention relates to physics, in particular to the determination of object coordinates.

Sonorus is used to determine the coordinates and motion parameters of an underwater object. Sonorus are installed on ships and can be mounted in the hull, be retractable or towed [1, 2, 4], and mounted on helicopters, and can be retractable, towed [2] and / or stationary on the ground [4 ], Aircraft and helicopters use disposable acoustic buoys. In recent years, unmanned aerial vehicles [5, 6] have been extensively developed, providing various tasks in various sectors from observation to delivery [7].

Due to the specificity of the acoustic signal and the limited propagation distances in the marine environment, non-sonor platforms need to overcome long distances to provide detection of the underwater object, as well as its coordinates and motion elements. For vessels operating at relatively low speeds, this requires significant investment in energy, financial and time. Using aircraft to search for underwater objects makes the operation much quicker, but therefore more expensive. The cost of disposable acoustic buoys is significantly higher, as the cost of one buoy is between $ 50,000 and $ 150,000.

The object of the invention is to increase the efficiency of the process of determining the coordinates of an underwater object, to speed up its operation, to reduce the cost of the process and to reduce environmental pollution. This is achieved by placing the underwater object search sonor on an unmanned flying machine. The proposed flying sonorboy (Fig. 1), located on an unmanned flying apparatus with a coaxial propeller (1), includes a control system for flight and sonor control (2), a transmitter data transmission (3), a winch sonor antenna lowering / lifting (4). ) and sonora (5).

The proposed flying sonorboy device works as follows: When it arrives at a specific location, the device lowers the sonor to the depth set and inspects the water layers. After the inspection, depending on the result or tactical task, the device continues the survey at the given location or flies to the new location and repeats the operation.

The device of the present invention enhances the efficiency of the underwater object coordinate determination process because sonor deployed on an unmanned aerial vehicle has much less time to operate, is much more economical than an airplane, helicopter or ship, is faster than a ship, pollutes nature less other sonora carriers and unlike single use sonorphs can be used multiple times. Occasionally, a flying sonoroy may be launched from the shore, thereby avoiding the use of a ship or manned aircraft at all as sonor carrier platforms.

Sonorboy is launched, according to the invention for industrial use, from the shore, ships or aircraft for a rapid reflection of the underwater situation. It can be used by naval forces to search for submarines, divers or mines, fishermen or fishery control officers for fish search or fish population control, hydrographic service specialists for seabed survey and other organizations with an interest in the underwater situation.
