RU2642224C1 - Method of improving efficiency of homing on underwater target of group of corrected underwater missile - Google Patents

Abstract

FIELD: military equipment.

SUBSTANCE: method for homing on underwater target of group of corrected underwater missiles of corresponding antisubmarine ammunition includes dropping antisubmarine ammunition at specified points of water impact, provision of specified airspeed of each antisubmarine ammunition, hovering at a set depth after the water impact at a given point and a separation of one of the corrected underwater missiles from the body of the antisubmarine ammunition. In the event of an underwater target enters the missile targeting area, it moves towards the target. Simultaneously with the release of one of the underwater missile which targeting area was entered by the underwater target, the signal is generated for the releasing the remaining missiles from the respective antisubmarine ammunition. In case of underwater targets enters the targeting area of any of remaining underwater missiles, the motion trajectory correction system of the underwater missile is conducts its targeting. The detonation of each antisubmarine missile is carried out when it passes the shortest distance relative to the underwater target or when it comes into contact with it.

EFFECT: increased efficiency of homing on the underwater target of group of underwater missiles.

Description

The invention relates to military equipment and can be used in the design of an anti-submarine ammunition shell with an adjustable trajectory in the underwater section of its movement and in the application and manufacture of anti-submarine ammunition used to destroy underwater targets from aircraft carriers and ship installations.

There is a known method of hitting submarines with a corrected anti-submarine bomb (see, for example, Russian Arms. Catalog. T. VII. High-precision weapons and ammunition. Military Parade CJSC. 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 not its splashdown, the immersion of a gravitational projectile under the influence of its weight and, at the same time, the deviation of the trajectory of its movement towards the target with the help of the trajectory correction system in the form of serially connected hydroacoustic receiving-emitting antenna, electronic unit and steering device.

The prototype of the claimed invention is the well-known "Method of improving the efficiency of pointing an underwater target of a corrected gravitational projectile anti-submarine bomb and a device for its implementation" (RF patent No. 2289783 C1, IPC F42B 21/00, published on December 20, 2006). According to a known method for increasing the efficiency of aiming an anti-submarine gravitational projectile corrected gravitational projectile on an underwater target, which includes serial or single-shot bombing at a given point on a water surface using an installation located on an aircraft carrier or ship, providing a given anti-submarine bomb flight speed on an air trajectory with using a parachute, temporarily holding the anti-submarine bomb at a given depth after its landing, then separating the corrector of a gravitational projectile from an anti-submarine bomb body after it is detected by an onboard sonar equipment of an underwater target and confirmed that it is in the guidance zone, the corrected gravitational projectile is submerged under the influence of its weight and, at the same time, its trajectory is deflected towards the target using a path correction system in the form of series-connected sonar transceiver antenna, electronic signal processing unit and steering device.

The disadvantage of both the analogue and the prototype is the relatively low efficiency of aiming underwater shells at an underwater target due to a significant limitation of functionality if it is necessary to share them as part of a group of ammunition distributed in a certain way in a given sea area along the route of the probable route of movement of the underwater target .

The objective of the present invention is to provide a method for improving the efficiency of pointing to an underwater target group of adjustable underwater shells, devoid of the above disadvantages.

The technical result is to increase the efficiency of aiming a group of underwater shells at an underwater target by expanding their functional capabilities, allowing interaction between all underwater shells that are part of the group, to remove and detonate them at the minimum possible distance from the underwater target.

To achieve the above objectives, a new method is announced to increase the efficiency of aiming at a submarine target of a group of adjustable underwater shells of the corresponding anti-submarine ammunition, the main essence of which includes:

- targeted serial dropping of anti-submarine ammunition or each individual anti-submarine ammunition firing at one of the specified splashdown points on a water surface using an installation located on an aircraft carrier or ship;

- providing a given flight speed of each anti-submarine ammunition on an air trajectory using a parachute;

- hovering at a given depth after splashing at a given point in the water surface of each anti-submarine munition using buoyancy;

- separation of one of the correctable underwater shells from the anti-submarine ammunition shell, in the event that an underwater target enters its guidance zone with a deviation, in the future, its trajectory towards the target by sounding pulses reflected from it;

- simultaneously with the aforementioned separation of one of the underwater shells, the guidance zone of which included an underwater target, giving them a signal to separate the remaining correctable underwater shells from the corresponding anti-submarine ammunition with a deviation, in the future, their trajectory towards the previously separated correctable underwater shell by receiving it probe pulses;

- in the event that after this an underwater target may enter the corresponding guidance zone of any of the other aforementioned underwater shells, the system for correcting the trajectory of the underwater shell will aim it at the target using probe pulses reflected from the target;

- undermining of each underwater anti-submarine projectile is carried out when passing the shortest distance relative to the underwater target or in contact with it.

One of the possible examples of the implementation of the claimed method of increasing the efficiency of aiming at an underwater target of a group of adjustable underwater shells is presented in FIG. 1, where are indicated:

1, 2, 3, 4, 5, and 6 - underwater ammunition after they are splashed at predetermined points;

7, 8, 9, 10, 11 and 12 - underwater shells after their separation from the corresponding underwater ammunition;

13 - guidance zone of the underwater projectile 9, separated from the ammunition 3;

14 - underwater target located in the guidance zone 13 of an underwater projectile 9.

After the reconnaissance of a moving underwater target, as well as its possible route and its parameters, using an aircraft carrier or ship at a calculated distance ahead of the underwater target, a group of anti-submarine munitions 1, 2, 3, 4, 5 and 6 are dropped, each of which is brought in a given point of the water surface, and the splash points themselves are placed on the water surface in the form of a conditional straight line with an interval excluding the possibility of the underwater target passing between the underwater ammunition undetected. When the underwater target 14 enters the guidance zone of any of the underwater shells 7, 8, 9, 10, 11 and 12, the corresponding underwater shell is separated from its ammunition, followed by its guidance on the underwater target 14. In this case, the underwater target 14 entered the guidance zone 13 underwater shell 9. Simultaneously with the separation of underwater shell 9, a signal is issued to separate from underwater ammunition 1, 2, 4, 5 and 6 underwater shells 7, 8, 10, 11 and 12. Since the underwater target 14 at the time of separation of the underwater shells 7, 8, 10, 11 and 12 will be located and outside their guidance zones (not shown), they will be guided by an underwater projectile 9, taking its probing pulses. As a result, the guidance system of the underwater projectile 9 will deviate the trajectory of its movement towards the underwater target 14, receiving the signals reflected from it, and the guidance system of the remaining underwater shells 7, 8, 10, 11 and 12 will deflect the corresponding trajectories in the direction of the underwater projectile 9. B As a result, the distance between the underwater target 14 and the underwater shells 7, 8, 9, 10, 11, and 12 will constantly decrease. If during the above-described joint movement of the underwater target 14 and underwater shells 7, 8, 10, 11 and 12, the underwater target 14 enters the guidance zone of any of the underwater shells 7, 8, 10, 11 and 12, then the guidance system of this underwater shell, in the guidance zone of which there was an underwater target 14, it will change its algorithm of operation and will reject the trajectory of its movement according to signals reflected from the underwater target 14. Underwater shells 7, 8, 9, 10, 11 and 12 will be detonated in case of contact with the underwater goal 14 or while passing kr tchayshego distance with respect to the underwater targets 14.

The proposed method for increasing the efficiency of aiming at an underwater target 14 of a group of underwater shells 7, 8, 9, 10, 11 and 12 allows them to attack the underwater target 14 together, providing the possibility of approaching it at the minimum possible distance of the entire group, taking into account specific conditions.
