Abstract

FIELD: guiding missiles and torpedoes.

SUBSTANCE: in the hydroacoustic system, the coordinates, speed and characteristics of the underwater target are determined and transmitted to the defensive-offensive system (DOS), where they determine the trajectory of the target, relative to which it manoeuvres, and the coordinates of the place where the torpedo enters the oncoming course, assign a missile with a torpedo warhead (TWH) or a torpedo and transmit its data to the control station (CS), where, if necessary, they supply the torpedo or TWH with the means to overcome the ice layer and launch a rocket or torpedo. On the rocket, its coordinates and speed are determined and transmitted through the control system to the DOS, where they determine the coordinates of the place of immersion of the TWH into water, calculate the trajectory and speed of the rocket to this place and transmit them to the CS, where commands are formed to point the missile at the place of immersion of the TWH into water and the command to separate the TWH from the rocket and transfer them to the rocket. The torpedo or the TWH, if necessary, pass the ice layer and the torpedo or the TWH are immersed into the water. On the torpedo or the TWH, its coordinates and speed are determined and transmitted through the control system to the DOS, where the trajectory and speed of the torpedo or the TWH to the place of entry into the oncoming course are calculated and transmitted to the CS, where the commands for guiding the torpedo or the TWH to the place of exit to the oncoming course are formed and transferred to a torpedo or the TWH. The DOS calculates the trajectory and speed of the torpedo or the TWH to the target and transmits them to the CS, where they form commands for aiming the torpedo or the TWH at the target and transmit them to the torpedo or the TWH.

EFFECT: probability of destroying a high-speed manoeuvring underwater target increases.

Description

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

Known methods of destroying an underwater target with a torpedo (RU 2513366, EN 2622051), in each of which an underwater target is detected and its current coordinates are determined; a missile with a torpedo warhead (TBC) is launched at the control station; on the rocket determine its current coordinates; determine the current coordinates of the place of immersion of the TBC into the water and calculate the trajectory of the rocket to this place; command is formed to guide the rocket to the place of immersion of the TBC into the water along the calculated trajectory; form a team of separation of the TBC from the rocket at the end of the calculated trajectory; on TBC determine its current coordinates; calculate the trajectory of the movement of the TBC to the target; commands are formed to guide the TBC to the target along the calculated trajectory.

However, such methods do not provide: - preventing a missile from colliding with third-party objects and bypassing the enemy's anti-missile defense zones by the missile; do not take into account information about such objects and zones; - the possibility of destroying an underwater target under the ice, because do not provide for overcoming the thickness of the ice; - high reliability of detection and tracking of the target and high accuracy of determining its coordinates, because do not provide for a review of the target from various directions; - prevention of collision of TBC with third-party objects, tk. do not take into account information about such objects; - optimization of the TBC approach to the goal, because do not provide for the withdrawal of TBC on a collision course; - optimization of the ratio of speed and maneuverability for TBC, because do not take into account the speed of the TBC and the target; - protection of the guidance of the TBC from opposition from the target, aimed at the homing head of the TBC.

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

The purpose of the invention is to increase the probability of destroying a high-speed maneuvering underwater target with a torpedo.

The proposed method is that:

- in the hydroacoustic system, they detect and accompany an underwater target, determine the current coordinates and speed of the target, as well as its characteristics, and transmit them to the defensive-offensive system (ONS);

- in the ONS, the trajectory of the target is determined, relative to which it maneuvers, the continuation of this trajectory is predicted, and the current coordinates of the place where the torpedo enters the oncoming course are determined;

- in the ONS, a missile with a TBC or a torpedo is assigned, as well as a control station, and the missile or torpedo data is transmitted to the control station;

- at the control station, if the target is under the ice, they supply the torpedo or TBC with the means to overcome the ice thickness;

- at the control station, they launch a missile with a TBC or a torpedo;

- on the rocket, its current coordinates and speed are determined and transmitted through the control station to the ONS;

- in the ONS determine the current coordinates of the place of immersion of the TBC into the water, and also calculate the trajectory and speed of the rocket to this place and transmit them to the control station;

- at the control station, commands are formed to guide the rocket to the place where the TBC is immersed in water along the calculated trajectory at the calculated speed and transmit them to the rocket;

- at the control station, a team is formed to separate the TBC from the rocket at the end of the calculated trajectory and transmit it to the rocket;

- on a torpedo or TBCh, if the target is under ice, they overcome the thickness of the ice and immerse the torpedo or TBCh into the water;

- on a torpedo or TBC, its current coordinates and speed are determined and transmitted through the control station to the ONS;

- in the ONS, the trajectory and speed of the torpedo or TBC movement to the place of entry into the oncoming course are calculated and transmitted to the control station;

- at the control station, commands are formed to guide the torpedo or TBCh to the place where they enter the oncoming course along the estimated trajectory at the calculated speed and transmit them to the torpedo or TBCh;

- in the ONS, after the torpedo or TBCh enters the oncoming course, the trajectory and speed of the torpedo or TBCh to the target are calculated and transmitted to the control station;

- at the control station, commands are formed to point the torpedo or TBC at the target along the estimated trajectory at the calculated speed and transmit them to the torpedo or TBC.

The hydroacoustic system is similar to the known one (iz.ru/news/647107). The target is similar to the Poseidon torpedo (www.gazeta.ru/army/2021/12/29/14372341.shtml). The coordinates and speed of the target are determined as a result of its review from various directions, and the characteristics of the target are determined as a result of its tracking.

ONS is similar to the known one (RU 2753498). The trajectory of the target, relative to which it maneuvers, is determined on the basis of an analysis of its actual trajectory. The place of exit of the torpedo or TBC to the oncoming course is chosen on the predicted continuation of the target trajectory from the condition of providing the torpedo or TBC with time sufficient to destroy the target.

Rocket, TBC, torpedo and control station are assigned based on their effectiveness. Information about the location of the target under the ice is transmitted to the control station along with the data of the TBC or torpedo. The means of overcoming the ice thickness are similar to those known (RU 2707233). On a rocket, torpedo and TBC, their coordinates and speeds are determined using onboard inertial navigation systems, corrected using a global satellite navigation system.

The place of immersion of the TBC into the water is chosen from the condition of providing the TBC with time sufficient to enter the oncoming course. The missile's trajectory and flight speed are calculated from the condition of preventing its collision with third-party objects and the condition of the missile bypassing the enemy's anti-missile defense zones.

The trajectory and speed of the torpedo or TBC is calculated from the condition of preventing its collision with third-party objects and the condition of the collision of the torpedo or TBC with the target at the required angle at the required speed. The coordinates and sizes of third-party objects are determined in the hydroacoustic system and transferred to the ONS.

The higher the speed of the torpedo, the higher its inertia and lower maneuverability. The ratio of speed and maneuverability for a torpedo or TBC in the final section of the trajectory is optimized by setting the speed necessary and sufficient to destroy the target in a collision.

The connection between the torpedo or TBC and the control station, as well as the control of the accuracy of pointing the torpedo or TBC is carried out by known methods (RU 2730749). Due to the accurate determination of the coordinates and speed of the target, a homing head on a torpedo or TBC is 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 station; 4 - missile with TBC; 5 - TBC, separated from the rocket, or torpedo.

Connections between blocks: 1-2 - current coordinates and speed of the target, as well as its characteristics; 2-3 - missile or torpedo data, estimated trajectory and speed of the missile to the place where the TBCh is immersed in water, the calculated trajectory and speed of the torpedo or TBCh to the place where it enters the oncoming course, as well as the calculated trajectory and speed of the torpedo or TBCh to the target; 3-2 - the current coordinates and speed of the rocket, as well as the current coordinates and speed of the torpedo or TBC; 3-4 - commands for guiding the missile to the place of immersion of the TBC into the water along the calculated trajectory with the calculated speed, as well as the command for separating the TBC from the rocket at the end of the calculated trajectory; 3-5 - commands for aiming a torpedo or TBCh at the place of entry into a collision course along the calculated trajectory at a calculated speed, as well as commands for pointing a torpedo or TBCh at a target along a calculated trajectory at a calculated speed; 4-3 - current coordinates and speed of the rocket; 5-3 - current coordinates and speed of the torpedo or TBC.
