Description

The invention relates to a means of detecting and destroying mobile underwater targets of the enemy.

Known radio-hydroacoustic buoy (RSL), as a means of detecting underwater objects. It is a radio-technical device, deployed at sea by ships or dropped from aircraft (LA), and is designed to obtain data on the underwater situation by acoustic methods, followed by their transmission over a radio channel to an aircraft, a ship or a coastal post. RSL is used to search for submarines (submarines), determine their coordinates and movement parameters, as well as to obtain data on the spectrum, intensity of underwater noise and acoustic fields of ships, ships and other objects. RSL is classified by carriers (aviation and ship), by the method of holding a place (anchor and floating), by the frequencies used (audio and low frequency), by the mode of operation (passive, active and passive-active, non-directional and directional), by the method of transmission information (continuously operating and on demand). The most widespread are passive, active, undirected and directed RSL. Structurally, they consist of a housing with electronic units, an information transmitter, power supplies and supporting devices, as well as a hydrophone (acoustic system) buried on a cable. RSL are usually equipped with braking devices to reduce the rate of descent, which are separated after splashdown. Passive omnidirectional RSLs make it possible to determine the presence of noise (their spectral composition and intensity) and to reveal the presence of PL. These RSL are used autonomously or in conjunction with explosive sound sources (VIZ) dropped from aircraft. Passive directional RSLs determine the bearing to the noise source. Active omnidirectional RSLs determine the range to the submarine by the echo signal (its place is determined by processing data from several RSLs, and the speed is determined by the Doppler frequency shift); active directional RSL give bearing and range to the object; passive-active directional RSLs operate in two modes. The information received by the RSL can be pre-processed directly on the buoy, and finally on the aircraft (ship) by the operator and the onboard digital computer. The detection range of submarines using the RSL reaches 10-12 km or more, the range of information reception over the radio channel is 60-80 km. [1]. The main disadvantage of the RSL is the limited functioning only as an information source and the impossibility of using it for physical impact on the detected underwater object with the aim of its destruction (destruction or incapacitation). At the same time, the time for hitting the detected target by other means is very limited, since the high maneuverability and secrecy of modern submarines significantly complicate its repeated detection.

It is known such a means of detecting and destroying mobile underwater targets of the enemy, as an anti-submarine bomb with an adjustable gravitational projectile [2], taken as a prototype of the invention. The corrected gravitational projectile is the striking element of the bomb and is equipped with a warhead, an explosive device and a trajectory correction system. The bomb has a system for launching and separating a projectile, as well as a parachute, a float with a non-return valve and a flexible connection with them. After splashdown, the bomb is held by a float and flexible coupling at a predetermined depth.

The projectile trajectory correction system is made in the form of a series-connected hydroacoustic receiving-emitting antenna, an electronic signal processing unit and a steering device. It has two hydroacoustic channels:

- underwater target detection channel and

- a channel for confirming that the target is in the zone of its catch-up by the projectile. The action of an anti-submarine bomb with an adjustable gravity

the projectile is carried out as follows (Fig. 1). A bomb with a corrected gravitational projectile (1) is dropped from an aircraft carrier (2) at the design point (3). In flight, it separates the parachute (4) and the float (5), inflated during the flight by the oncoming air flow through the non-return valve. The parachute (4) slows down the movement of the bomb after separation from the carrier (2), and the float (5) with the help of a flexible connection (6) keeps the bomb at a given depth from the water surface (7). The underwater target (8) is detected by the corrected gravity projectile (1) of the bomb after it enters the target detection channel (9) of the projectile trajectory correction system. The separation of the corrected gravitational projectile (1) is carried out immediately after the target (8) enters the zone of the channel, confirming its location in the zone (10) catching up with the target by the projectile (1), while the projectile is launched, its guidance (11) at the target (8 ) by the commands of the trajectory correction system, hitting it, triggering an explosive device and hitting a target. The driving force of the gravitational projectile in the area of immersion and targeting is the force of its negative buoyancy. Commands to separate the projectile and the operation of its rudders are generated in the electronic unit of the projectile, taking into account the data of its hydrodynamic characteristics, which determine the target catch-up zone and the necessary trajectory correction angles.

The disadvantage of an anti-submarine bomb with an adjustable gravitational projectile is the impossibility of its use to illuminate the underwater situation, since it does not have a communication channel with the control point and the target detection range is too small to solve this problem. Therefore, the bomb is used only according to target designation data from other sources of information.

The aim of the invention is to develop a universal search and strike means in the form of an aviation floating underwater projectile, capable of detecting a moving enemy underwater object at ranges corresponding to the range of search means, transmitting information about target detection to the control point and attacking the detected object when entering the affected area of the underwater projectile ...

This goal is achieved due to the fact that an aviation floating underwater projectile is proposed, including an underwater projectile having a warhead, an explosive device and a trajectory correction system with a hydroacoustic receiving and receiving antenna, an electronic signal processing unit and a steering device, a detachable tail compartment with a separation device located in it, a parachute, a float with a non-return valve and a flexible connection between the float and the projectile, characterized in that, in addition, the underwater projectile has a transceiver radio device with a current source, a cable and a transceiver antenna and a detachable bow compartment with a coil, a cable with hydrophones and a node for attaching the compartment to the projectile body.

In a variant version, the underwater projectile is equipped with a power plant and a propeller.

The device of an aviation floating underwater projectile is illustrated by the drawings (Fig. 2 and 3), which show the general structure of an aviation floating underwater projectile (Fig. 2) as a means of detecting underwater objects, as well as the device of its striking element - an underwater projectile (Fig. 3) ... The numbers in FIG. 2 and 3 are designated: 4 - parachute; 12 - hydroacoustic receiving-emitting antenna; 13 - the body of the aircraft floating underwater projectile; 14 - warhead; 15 - explosive device; 16 - electronic unit; 17 - radio transceiver; 18 - steering wheel control mechanism (steering machines); 19 - rudders; 20 - unit for attaching the parachute slings to the cable-rope; 21 - tail compartment body; 22 - stabilizers; 23 - float with antenna; 24 - non-return valve; 25 - cable-cable (flexible connection with the cable) connecting the float and its transmitting-receiving antenna with a sealed cable-connector (28); 26 - parachute slings; 27 - unit for attaching the tail compartment and cable-cable (25) to the aviation floating underwater projectile with a device for separating them and breaking the cable-cable; 28 - sealed cable connector; 29 - cable connecting the sealed cable-connector (28) with the radio transceiver (17); 30 - cable channel; 31 - cable connecting hydrophones with electronic unit (16); 32 - unit for attaching the bow compartment to the body of the underwater projectile and separating from it; 33 - the body of the bow compartment; 34 - sealed cable connector with cable break device; 35 - hydrophone; 36 - coil with cable and hydrophones; 37 - coil bushing.

These structural elements of the aircraft floating underwater projectile perform the following functions.

The tail compartment (21) is used to accommodate and release the float with the antenna (23) and the parachute (4) (Fig. 2). As in the prototype, it stabilizes the underwater projectile on the trajectory after being dropped by the carrier (2) at the design point (3) (Fig. 4). The parachute provides deceleration of the aviation floating underwater projectile before it splashes down, and the float with the antenna (23) (Fig. 2) is inflated by the non-return valve (24) with the counterflow of air and ensures that the projectile splashed down afloat at a depth corresponding to the length of the flexible connection, which unlike the prototype, it has a cable (25) (Fig. 4).

The nasal compartment (33) is used to accommodate the means for detecting underwater objects - a cable (31) wound on a reel (36) and hydrophones (35). It ensures the operation of an aviation floating underwater projectile as a means of underwater observation and detection of underwater objects. After splashing down the projectile, immersing it to a depth and holding it by a float with an antenna (23), the bow compartment (33) is separated from the body of the underwater projectile (13) with the help of the attachment point (32) and, under the action of its negative buoyancy force, submerges to a depth corresponding to the length of the cable (31) wound on the reel (36) (Fig. 4). Hydrophones (35) connected to the electronic unit (16) (Fig. 2) are activated and monitor the underwater environment in order to detect moving underwater objects in their detection zone (38). With the detection of an underwater object, the electronic unit (16) transmits information about it to the control point via a communication line, which includes a radio transceiver device (17), a flexible communication cable (cable-cable) (25) and a transmitting antenna (39).

If the target (8) approaches the aeronautical floating underwater projectile (13) within the range of its hydroacoustic receiving and receiving antenna (12), on command from the control point, it begins to work and search for the target, forming a target detection zone (9), similar to the prototype (Fig. 1). After detecting the target by the hydroacoustic receiving-emitting antenna (12) and confirming the fact of its being in the zone (10), which ensures its catch-up by the underwater projectile when pointing (11), the cable (31) for giving the underwater projectile freedom of maneuver is cut off using the device for breaking the sealed cable-connector (34) and, together with the nose compartment (33), sinks, the tail compartment (21) is simultaneously separated, and the projectile, under the control of its trajectory correction system, is directed (11) to the target and strikes it.

Thus, the aircraft floating underwater projectile has two sonar target detection channels - one long-range detection channel, including hydrophones (35) and an electronic signal processing unit (16), and a second short-range detection channel, including a sonar receiving and emitting antenna (12) and an electronic processing unit. signals (16). In addition, within the limits of the action of the channel for short-range target detection, using the electronic signal processing unit, the space region (10) is calculated, at the entrance to which the target catch-up and its defeat is ensured (Fig. 1).

Equipping an underwater projectile with a power plant and a propeller can significantly increase the area (10) of hitting the target by an underwater projectile (Fig. 1).

The technical result of the invention is an aviation floating underwater projectile, which combines the properties of a positional means of illumination of the underwater environment and the properties of a mobile means of destruction of an underwater target detected by it. It provides observation of the underwater situation in a given sea area in order to detect mobile underwater objects, communication with a control point, as well as defeat a detected mobile underwater object on command from a control point or independently when it enters the affected area of an underwater projectile.
