RU2776625C1 - Method for destroying underwater target with torpedo - Google Patents

Abstract

FIELD: military technology.

SUBSTANCE: invention relates to missile and torpedo guidance systems. The sonar system detects and accompanies an underwater target, determines the coordinates, speed and characteristics of the target and transmits them to the defensive and offensive system (DOS), where they assign a missile with a torpedo warhead (TWH) or a torpedo and transmit its data to the control station, where, if necessary, they supply TWH with means of overcoming the ice thickness and launch a rocket or a torpedo. On the rocket, its coordinates and speed are determined and transmitted through the control station to the DOS, where the trajectory and flight speed of the rocket are calculated and transmitted to the control station, where commands are formed to guide the rocket to the target area and the command to separate the TWH from the rocket at the end of the calculated trajectory and transmit them to the rocket. On the TWH, if necessary, overcome the thickness of the ice and immerse the TWH in water. On a torpedo or TWH, its coordinates and speed are determined and transmitted through the control station to the DOS, where the trajectory and speed of the torpedo or TWH are calculated and transmitted to the control station, where commands are formed to point the torpedo or TWH at the target and transmit them to the torpedo or TWH.

EFFECT: method provides an increase in the probability of destroying underwater targets with a torpedo.

Description

The invention relates to missile and torpedo guidance systems, namely to defensive-offensive systems, and can be used to destroy underwater targets, including those under ice, missiles with a torpedo warhead and torpedoes.

Known methods for the destruction of underwater targets (RU 2513366, EN 2622051), in each of which at the control stations launch missiles with a torpedo warhead (TBC); on missiles with TBC, their current coordinates are determined and transmitted to the appropriate control stations; calculate trajectories for missiles with TBC; at the control stations, commands are formed to guide missiles with TBC along the calculated trajectories to the target location area and transmit them to the corresponding missiles; at the control stations, teams are formed to separate the TBC from the missiles at the end of the calculated trajectories and transmit them to the corresponding missiles; determine the current coordinates of the TBC; calculate trajectories for TBC; form commands to guide the TBC along the calculated trajectories on the target.

However, such methods do not provide: - preventing missiles from colliding with third-party objects and bypassing enemy missile defense zones by missiles, since they do not take into account information about such objects and zones; - the possibility of destroying underwater targets located under the ice, since they do not provide for overcoming the thickness of the ice; - high reliability of detection and tracking of targets and high accuracy of determining their coordinates, since they do not provide for an overview of targets from different directions; - protection of targeting TBC from opposition from targets directed at the homing heads of TBC.

These shortcomings of the known methods reduce the probability of destroying targets.

The purpose of the invention is to increase the probability of destroying underwater targets.

The proposed method is that:

- in the hydroacoustic system, they detect and track underwater targets, determine the current coordinates and speeds, as well as the characteristics of the targets and transmit them to the defensive-offensive system (ONS);

- in the ONS, missiles are assigned to deliver TBCs to target areas, as well as torpedoes and transmit their data to the appropriate control stations;

- at control stations, if targets are found under ice, they supply TBC with shaped charges to overcome the ice thickness;

- at control stations they launch rockets from TBC and torpedoes;

- on missiles with TBC, their current coordinates and speeds are determined and transmitted, through the appropriate control stations, to the ONS;

- in the ONS, trajectories and velocities for missiles with TBC are calculated and transmitted to the appropriate control stations;

- at the control stations, commands are formed to guide missiles with TBC along the calculated trajectories with estimated speeds in the target location area and transmit them to the corresponding missiles;

- at the control stations, teams are formed to separate the TBC from the missiles at the end of the calculated trajectories and transmit them to the corresponding missiles;

- on TBC, if targets are under ice, after touching the ice surface, shaped charges are detonated and TBC is immersed into water through holes formed in the ice;

- on torpedoes and TBCs, their current coordinates and speeds are determined and transmitted, through the appropriate control stations, to the ONS;

- in the ONS, trajectories and speeds for torpedoes and TBCs are calculated and transmitted to the appropriate control stations;

- at the control stations, commands are formed for guiding torpedoes and TBCs along the calculated trajectories with calculated speeds on the target and transmit them to the corresponding torpedoes and TBCs.

The hydroacoustic system is similar to the known one (https://iz.ru/news/647107#ixzz4QxkkRvIA). The coordinates and speeds of targets are determined as a result of their review from various directions, and the characteristics of the targets are determined as a result of their tracking. ONS is similar to the known one (RU 2753498).

Rockets with TBC and torpedoes are assigned based on their effectiveness. On TBC overcoming the thickness of the ice is carried out in a known manner (RU 2707233). On missiles with TBCs, torpedoes and TBCs, their coordinates and speeds are determined using onboard inertial navigation systems corrected using a global satellite navigation system.

Trajectories and velocities for missiles with TBC are calculated based on the need to prevent their collision with third-party objects and the need for missiles to bypass the enemy's anti-missile defense zones.

The connection of torpedoes and TBCh with control stations, as well as the control of the accuracy of their guidance is carried out by known methods (RU 2730749). Due to the accurate determination of the coordinates and speeds of targets, homing heads on torpedoes and TBCs are not required.

The proposed method can be implemented in the system, the block diagram of which is shown in the drawing.

Blocks: 1 - hydroacoustic system; 2 - ONS; 3 - control stations; 4 - missiles with TBC; 5 - torpedoes; 6 - TBC separated from missiles.

Connections between blocks: 1-2 - current coordinates and speeds, as well as characteristics of underwater targets; 2-3 - data of assigned missiles with HBCs and torpedoes, as well as calculated trajectories and speeds for missiles with HBCs, torpedoes and HBCs separated from missiles; 3-2 - current coordinates and speeds of missiles with TBC, torpedoes and TBC separated from missiles; 3-4 - commands for guiding missiles with TBM along the calculated trajectories with estimated velocities in the target location area, as well as commands for separating the TBCh from missiles at the end of the calculated trajectories; 3-5 - commands for guiding torpedoes along the calculated trajectories with estimated speeds on the target; 3-6 - command guidance TBC, separated from the missiles, along the estimated trajectories with estimated speeds on the target; 4-3 - current coordinates and speeds of missiles with TBC; 5-3 - current coordinates and speeds of torpedoes; 6-3 - current coordinates and velocities of TBC separated from missiles.
