Description

The invention relates to means for detecting and destroying enemy moving underwater objects.

Known sonar buoy (RSL) as a means of detecting underwater objects. It is a radio engineering device placed at sea by ships or dropped from aircraft, and is designed to receive data on the underwater situation by acoustic methods with their subsequent transmission via radio to an aircraft, ship or coastal post. The 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 are classified by carriers (aviation and ship), by the method of holding the place (anchor and floating), by the frequencies used (sound range and low-frequency), by the mode of operation (passive, active and passive-active, omnidirectional and directional), by the method of transmission information (continuous and on request). The most widely used passive, active, non-directional and directional 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. RSLs 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 detect the presence of submarines. These RSLs are used autonomously or in conjunction with explosive sound sources dropped from an aircraft. Passive directional RSL determine the bearing to the noise source. Active non-directional RSLs determine the distance to the submarine by an 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 preliminary processed directly on the buoy, and finally on the aircraft (ship) by the operator and the onboard computer. The detection range of submarines with the help of the RSL reaches 10-12 km or more, the range of receiving information via a radio channel is 60-80 km [1].

Known sonar buoy jet (RGBR), which is a combination of RSL and missiles, adopted as a prototype of the invention. It includes elements of the RSL (hull, battery, parachute system, transmitter, receiver with hydrophones, memory device, cable-rope, antenna, automatic release mechanism, control unit, clockwork), rocket elements (rocket engine and stabilizer), as well as other devices - separation mechanism, data input device, splashdown sensor, float and gas generator [2].

The separation mechanism is used to separate the rocket engine at a given point in the trajectory, the data input device is used to enter the flight task into the RSL, the splashdown sensor is to fix the moment of splashdown of the RSL, the float is to hold the antenna and ensure the RSL is immersed to a given depth, and the gas generator is for filling float with compressed gas.

Before the shot, the RGBR is loaded into the launcher, the trajectory is calculated, the flight task is entered into the data input device, the launcher is directed, and the launch is carried out. At a given point in the trajectory, the rocket engine is separated and the parachute system is activated, which provides braking of the RSL before entering the water. After splashdown, the gas generator is activated and inflates the float. The hydrophone (acoustic system) is buried on a cable-cable, comes into working position and begins to survey the underwater environment. When a target is detected, information about it is transmitted to the control point via a radio channel.

Instead of a gas generator, the float can be inflated during the flight of the RSL in the air by using a non-return valve, as is implemented in an aviation anti-submarine bomb [3].

The disadvantage of the RSL and RBR is their functional limitation, which consists in working only as a source of information. They do not have the means of physical influence on the underwater object they have discovered. The use of means of destruction against a detected target is limited by the time of their possible use after the target is detected due to its high maneuverability and secrecy inherent in modern submarines.

Known rocket anti-submarine projectile (RPS), considered as an analogue of the invention [4]. It has a rocket engine (RD), a stabilizer and a warhead, which is used as a homing underwater projectile (PS), a RD separation mechanism, a remote device, a parachute, a buoy with a buoy, a gas generator, a PS penetration mechanism and a self-destruction device.

PS is a damaging agent. It is equipped with an explosive charge and a non-contact target detection system operating in two modes: passive - for primary target detection and active - for homing to the target and hitting it.

The separation mechanism and the remote device are used to separate the missile and warhead before splashdown, the parachute - to ensure stabilization and braking of the PS in the air section of the trajectory until it splashes down, the buoy with a buoy and a deepening mechanism - to install the PS on a given recess, the self-destruction mechanism - for liquidation of the PS after a specified time.

The possibility of salvo firing of RPS from the launcher allows several PS to be delivered to the target detection site within a short time. If the target is not detected, it is possible to select them for reuse. To aim at a target, an underwater projectile uses the force of negative buoyancy or is equipped with a propulsion unit.

Before firing, the RPS is loaded into the launcher, its trajectory is calculated, the launcher is aimed and firing is performed. At a given point in the trajectory, the rocket engine is separated, the parachute is activated, and the PS is slowed down before entering the water. After splashdown, the PS turns on the gas generator and fills the buoy with compressed gas, the buoy is unwound, and the PS sinks to a given recess, where its non-contact target detection system is switched on in the passive mode and the target is searched. After the target is detected by the passive channel, the non-contact detection system turns on the active channel, and after the target is captured by it, the PS is separated from the buoyrep and, controlled by the rudders, aims at the target and hits it.

RPS can additionally be equipped with a signaling system that serves to indicate the location of the target detection by a signal rocket or a radio signal.

The disadvantage of RPS is the impossibility of using it to illuminate the underwater situation, since it does not have a communication channel with the control point. Therefore, RPS is used only according to the target designation of the ship or other sources of information.

The aim of the invention is to develop a single search and strike tool capable of detecting a moving enemy underwater object at ranges corresponding to the range of the search tools, transmit information about this to a control point, and attack it when the target approaches the range of the strike tool.

This goal is achieved due to the fact that a reactive floating underwater projectile is proposed, which is a rocket having a rocket engine with a device for its separation and a stabilizer, and an underwater projectile placed in the head of the rocket, having a search acoustic system for detecting underwater targets with a control device and a current source , a cable with hydrophones, a coil, a cable attachment point to the body of an underwater projectile, a radio transceiver and an antenna, as well as a parachute, a float with a flexible connection with an underwater projectile.

Additionally, the underwater projectile contains a braking and stabilization compartment connected to the rear part of the underwater projectile body and the possibility of separation from the projectile body, a rocket engine connected to the rear part of the braking and stabilization compartment and configured to be separated from the braking and stabilization compartment, the braking and stabilization compartment includes a parachute and a float, while the float has an antenna and a non-return valve with the possibility of filling the float with gas, the underwater projectile includes a warhead with an explosive device, the underwater projectile contains an electronic unit and a radio transmitter with the ability to transmit information to the control point, the underwater projectile in the head part has a search compartment acoustic system with the possibility of separation from the body of the projectile, the compartment of the search acoustic system includes a transceiver antenna and hydrophones mounted on a cable that is wound on a reel with the possibility of unwinding to a depth equal to the length of the cable, while the hydr The phones are connected to the electronic unit by a cable.

In a variant version, the underwater projectile is additionally equipped with a power plant and a propulsion unit.

The device of a reactive floating underwater projectile is illustrated by drawings (figure 1 and 2). Figure 1 shows the general device of a reactive floating underwater projectile assembly with a missile part and a search acoustic system for detecting underwater targets. Figure 2 shows the device underwater projectile. The numbers in figures 1 and 2 indicate: 1 - cable connecting the hydrophones of the search acoustic system for detecting underwater targets with the electronic unit (9); 2 - hydrophone; 3 - coil with cable and hydrophones; 4 - coil bushing; 5 - transceiver antenna of the acoustic system for short-range detection of an underwater target and homing to it; 6 - body of an underwater projectile; 7 - warhead; 8 - explosive device; 9 - electronic unit; 10 - radio transceiver; 11 - steering mechanism (steering machines); 12 - rudders; 13 - attachment point of the parachute lines to the cable-cable; 14 - body of the braking and stabilization compartment; 15 - parachute; 16 - stabilizers; 17 - rocket engine separation device; 18 - rocket engine; 19 - float with antenna; 20 - non-return valve; 21 - cable-cable (flexible connection), connecting the float and its transceiver antenna with a sealed cable-connector (24); 22 - parachute lines; 23 - attachment point for the deceleration and stabilization compartment to the underwater projectile with its separation device; 24 - sealed cable connector with a cable break device; 25 - cable-cable connecting the sealed cable-connector (24) with the radio transceiver device (10); 26 - cable channel; 27 - attachment point of the compartment of the search acoustic system for detecting underwater targets to the body of the underwater projectile and separation from it; 28 - case of the compartment of the search acoustic system for detecting underwater targets.

The action of a floating underwater projectile is shown in figures 1, 3 and 4. Figure 3 shows the surface of the sea (29) and the launch from a surface ship (30) of a floating underwater projectile (31) moving along an air trajectory (32). At a given point in the trajectory, the rocket engine (18) is separated and the parachute (15) and float (19) placed in the braking and stabilization compartment (14) (figure 1) are activated. The parachute provides braking of the reactive floating underwater projectile before it splashes down, and the float (19) with the antenna (33) and the non-return valve (20) is inflated by the oncoming air flow and ensures that the splashed projectile is kept at the appropriate length of the cable-rope (21) recess.

The compartment of the search acoustic system for detecting underwater targets (28) is used to accommodate means for detecting underwater objects - a cable (1) wound on a reel (3) and hydrophones (2), which provide underwater observation and detection of underwater objects. After splashdown of the projectile and its deepening, the case of the search acoustic system compartment (28) with the recoil of the fasteners (27) is separated from the body of the underwater projectile (6) and is immersed to a depth equal to the length of the cable (1) unwound from the reel (3). The hydrophones (2) connected to the electronic unit (9) acting as a control device are activated and monitor the underwater environment in the detection zone (34). With the detection of an underwater object (35), the electronic unit (9) transmits information about this to the control point through a radio transceiver (10), a cable (21) and a transmitting antenna (33).

When approaching the target (35) with a floating underwater projectile (6), its hydroacoustic receiving and emitting antenna (5) turns on in active mode and searches for a target in its detection zone (36) (figure 4). With the detection of the target at the command of the electronic unit (9), the cable (21) is cut off using the device for breaking the sealed cable connector (24), and the underwater projectile (6) is aimed (37) at the target (35) under the control of the electronic unit (9) and steering gear and hits her. To attack high-speed underwater targets, when the immersion speed of an underwater projectile is not enough to catch up with them [5], it is additionally equipped with a power plant and a propulsion unit.

Thus, a reactive floating underwater projectile has two independent hydroacoustic target detection channels - a long-range detection channel with hydrophones (2) and a short-range detection and targeting channel with a hydroacoustic receiving and emitting antenna (5), controlled by an electronic unit (9) for signal processing and command generation aiming the projectile at the target.

The technical result of the invention is a reactive floating underwater projectile, which is both a positional means of observing the underwater environment in a given area, and a homing strike tool that serves to destroy an underwater target it has detected. It provides control of the underwater situation in a given sea area, communication with a command post and defeat of a detected mobile underwater object on command from a command post or independently when it enters the kill zone.
