The antisubmarine bomb is provided with a float with a non-return valve connected to it by a flexible coupling, the valve is filled with the incoming flow of air during the bomb flight in the air trajectory. The separated corrected gravitational projectile is provided with an additional hydroacoustic channel of submerged target detection and confirmation of its presence in the guidance zone, during its retention at the preset depth. The parachute and float with the non-return valve are located in the brake compartment of the bomb.

Description

Field of Invention

The invention relates to ammunition, namely to anti-submarine bombs, incorporating a gravitational shell with an adjustable trajectory in the underwater section of its movement, and can be used in the development and manufacture of anti-submarine weapons used for bombing underwater targets from aircraft carriers and ship installations.

The current level of technology

There is a method of hitting submarines with a corrected anti-submarine bomb (see, for example, Russian Arms. Catalog. T.VII. High-precision weapons and ammunition. AOZT Military Parade. M. - 1997, pp. 337, 338) which includes targeted serial bombing at a given point on a water surface, for example, using an installation located on an aircraft carrier or ship, providing a given bomb speed on an air path, for example, using a parachute, separating the gravitational projectile from the anti-submarine bomb body after splashdown its immersion gravity of the projectile under the action of its own weight and, at the same time, the deviation of its trajectory towards the target motion via path correction system in the form of serially connected priemoizluchayuschey sonar antenna, an electronics unit and a steering device. There is also a bomb for the implementation of this method, for example, C3B, taken by the authors as a prototype, comprising a body, launch and separation system, a parachute, a brake compartment and an adjustable gravity underwater projectile with a warhead, an explosive device and a trajectory correction system in the form of a series-connected sonar receiving-emitting antenna , an electronic unit and a steering device, which begins to work after the separation of the gravitational projectile from the bomb body at the time of splashdown. During the immersion of the gravitational projectile when an underwater target is detected in the detection zone (in the radiation pattern of the receiving-emitting antenna), the electronic unit issues commands to the steering device and the gravitational projectile is aimed at the target within the guidance zone (path correction angle), determined by the hydrodynamic characteristics of the gravitational projectile. In the absence of a target in the detection zone, a gravitational projectile under the influence of its own weight continues free immersion until it meets the ground (Technical description and operating instructions SINM.771546.001 TO. FSUE GNPP "Region").

The disadvantage of both the method of aiming the corrected gravitational projectile on the underwater target and the anti-submarine bomb itself with the correctable gravitational projectile is their low efficiency of hitting the target with possible large targeting errors and a limited guidance zone (angle of trajectory correction) of the gravitational projectile.

SUMMARY OF THE INVENTION

Thus, the objective of this invention is to create a new way to increase the efficiency of pointing to an underwater target of a corrected gravitational projectile anti-submarine bomb and devices for its implementation, providing a technical result aimed at eliminating the disadvantages noted in the prototype.

To eliminate the drawbacks noted in the prototype, a new method is proposed for increasing the efficiency of pointing an anti-submarine gravitational projectile corrected gravitational projectile onto an underwater target, which includes targeted serial bombing at a given point on a water surface, for example, using an installation located on an aircraft carrier or ship, ensuring a given speed the flight of a bomb on an air trajectory, for example, using a parachute, the separation of the gravitational shell from the body of the anti-submarine bomb after it splashdown, immersion of a gravitational projectile under the influence of its weight and, at the same time, deviation of its trajectory towards the target using the trajectory correction system in the form of serially connected hydroacoustic receiving-emitting antenna, electronic unit and steering device, in which, unlike the prototype, temporary holding at a given depth of the anti-submarine bomb after its landing, and the separation of the corrected gravitational shell from the bomb body and its further immersion the water under the action of its weight is carried out after the discovery of his on-board sonar equipment underwater targets and confirm its location in the guidance area.

To implement the claimed method of increasing the efficiency of aiming a correctable gravitational shell on an underwater target, a new design of an anti-submarine bomb is proposed, comprising a hull, launch and separation system, a parachute, a brake compartment, a detachable correctable gravitational underwater shell with a warhead, an explosive device and a trajectory correction system connected sonar transceiver antenna, electronic unit and steering device, which, unlike rototype, equipped with a flexible connection connected to it with a float with a non-return valve, filled with the oncoming air stream during the flight of the bomb on an air trajectory, and its detachable corrected gravitational shell - with an additional sonar channel for detecting the underwater target and confirming its presence in the guidance zone while holding it on a given depth, while the parachute and the float with a non-return valve are placed in the brake compartment of the bomb.

The figure 3 shows a parachute 4 connected to the brake compartment 3 with slings 23, a float 5 with a non-return valve 20 and a flexible connection 19 connecting the float 5 with the brake compartment 3 of an anti-submarine bomb.

The implementation of the invention

The anti-submarine bomb 1 contains a housing 7, to the rear of which a launch and separation system 2 and a brake compartment 3 are attached. In the brake compartment 3 of the bomb 1, a parachute 4 and a float 5 are placed, while the parachute is attached by slings 23, and the float by means of a flexible connection 19 to the brake compartment 3. The float 5 contains a non-return valve 20, through which the incoming air flow in the air section 16 of the flight path of the bomb 1 fills its internal volume. Inside the housing 7 of bomb 1 is placed and held by means of a launch and separation system 2, an adjustable gravitational projectile 6. In turn, an adjustable gravitational projectile 6 contains a radiating antenna 12 of the path correction system located in its head part (12, 14, 8, 9), emitting antennas 13 of the additional sonar detection channel (13, 14, 8) of the underwater target 18 and confirmation of its location in the guidance zone 22, receiving antennas 14 of the path correction system (12, 14, 8, 9) and the additional detection channel (13, 14, 8). In the tail part of the corrected gravitational projectile 6 there is an electronic unit 8 for processing signals of the path correction system (12, 14, 8, 9) and an additional detection channel (13, 14, 8) for underwater target 18 in the guidance zone 22 and the steering device 9. In addition , adjustable gravitational shell 6 contains a warhead 10 and an explosive device 11.

After separating the bomb 1 from the aircraft carrier 15 using the launch and separation system 2, the parachute 4 and the float 5 are ejected from the brake compartment 3. The dome of the parachute 4 is filled under the influence of the oncoming air flow and provides a predetermined rate of descent in the air section 16 of the flight path of bomb 1, and also there is a pressurization of the float 5 by an oncoming flow of air through the non-return valve 20. When the bomb 1 is brought into action due to the parachute, it suddenly brakes and freezes 17 on the float 5. At the same time, on an additional hydroacoustic detection channel is operating (13, 14, 8), the underwater target 18 is located in the detection zone 21 and its location in the guidance zone 22 is confirmed. If the underwater target 18 was not detected in the detection zone 21 or was absent in the guidance zone 22, for example, due to possible large target designation errors, the anti-submarine bomb 1 with its detachable gravitational projectile 6 will be held in hover mode 17 on the float 5 until the moment the submarine ate 18 in the guidance zone 22 and, accordingly, receiving a confirmation signal about this with an additional sonar detection channel (13, 14, 8). If an additional sonar channel (13, 14, 8) detects an underwater target 18 in the detection zone 21 and confirms its location in the guidance zone 22, the electronic signal processing unit 8 issues a command to separate the corrected gravitational projectile 6, through which the launch and separation system is triggered 2 and the detached gravitational projectile 6 begins to dive due to its weight. At the same time, the trajectory correction system (12, 14, 8, 9) works, which, using the steering device 9, deflects the immersion path of the corrected gravitational projectile towards the underwater target 18. When the gravitational projectile 6 hits the underwater target 18, the fuse 11 undermining the warhead 10.

The positive effect of the proposed technical solution to improve the efficiency of pointing an underwater target of a corrected gravity projectile is confirmed by theoretical and theoretical justifications, and the design of the claimed anti-submarine bomb that implements this technical solution was verified by testing it in laboratory-bench and field conditions.

Industrial applicability

The present invention can be used in weapons systems using an adjustable gravity projectile to destroy underwater targets. Although the invention has been described using an example of its specific implementation for a bomb dropped from an aircraft carrier, it also applies to bombs dropped from surface ship installations. This description does not limit the scope of patent claims defined only by the claims.
