Abstract

FIELD: military.

SUBSTANCE: method for guiding missiles and torpedoes. In the hydroacoustic system, the coordinates, speeds and characteristics of underwater targets are determined and transmitted to the defensive-offensive system (DOS), where they determine the trajectory of the targets relative to which they manoeuvre, and the coordinates of the place where the torpedo carrier (TC) enters the oncoming course, TC or TC-bearing rocket are assigned and transmit their data to the control station (CS), where, if necessary, they supply the TC with the means to overcome the ice thickness and launch the TC or rocket. 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 TC into water, calculate the trajectory and speed of the rocket to this place and transmit them to the CS, where commands to point the missile at the place of immersion of the TC into water and the command to separate the TC from the rocket are generated and transmitted to the rocket. On the TC, if necessary, the ice thickness is penetrated and the TC is immersed in the water. TC coordinates and speed are determined and transmitted through the control system to the DOS, where the trajectory and speed of the TC to the place of entry into the oncoming course are calculated and transmitted to the CS, where the commands for guiding the TC to the place of exit to the oncoming course are generated and transmitted to the TC. TC coordinates and speeds are determined and transmitted through the TC and control system to the DOS, where the trajectories and speeds of the TC and torpedoes to targets are calculated and transmitted to the control system, where the instructions for aiming the HP at the target and the commands for separating torpedoes from the TC are generated and transmitted to the TN. Commands for aiming torpedoes at the target are formed on the control system and transmitted through the TC to the torpedoes.

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

Description

The invention relates to missile and torpedo guidance systems, namely to defensive-offensive systems, and can be used to destroy group high-speed maneuvering underwater targets, including those under ice, by groups of torpedoes separated from torpedo carriers.

Known methods of destroying underwater targets torpedoes, separated from the torpedo-carrier (RU 2014121555, EN 2742904), each of which detect underwater targets and determine their current coordinates; a torpedo carrier (TN) is launched at the control station; on the HP determine its current coordinates; on detachable torpedoes, their current coordinates are determined; calculate the trajectory of the movement of HP and detachable torpedoes to the targets; form commands for guiding the HP to the target along the calculated trajectory; command for separating torpedoes from HP at the beginning of the calculated trajectories is formed; commands are formed to guide torpedoes, separated from the HP, at the target along the calculated trajectories.

However, such methods do not provide: the ability to determine the number of targets before launching the TN; the possibility of destroying underwater targets under the ice, because 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, because do not provide for an overview of targets and their area of location from various directions; prevention of collision of HP and torpedoes with third-party objects and with each other, because do not take into account information about such objects and about each other; optimization of the TN approach to goals, because do not provide for the withdrawal of HP on a collision course; the possibility of redistributing targets between torpedoes after separating them from the HP; optimization of the ratio of speed and maneuverability for torpedoes, as do not take into account the speed of torpedoes and targets; protection of torpedo guidance from counteraction from targets directed at torpedo homing heads.

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

The purpose of the invention is to increase the probability of destroying high-speed maneuvering underwater targets with torpedoes.

The proposed method is that:

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

- in the ONS, they determine the trajectory of the targets, relative to which they maneuver, predict the continuation of this trajectory and determine the current coordinates of the place where the HP enters the oncoming course;

- in the ONS, a TN or a rocket with a TN, as well as a control station are assigned, and the data of the TN or rocket is transmitted to the control station;

- at the control station, if the targets are under the ice, they supply the HP with the means to overcome the ice thickness;

- at the control station, a TN or a rocket with TN is launched;

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

- in the ONS, the current coordinates of the place of immersion of the HP installed on the rocket into the water are determined, as well as the trajectory and speed of the rocket flight to this place are calculated and transmitted to the control station;

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

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

- on the HP, in the case of finding targets under the ice, they overcome the thickness of the ice and immerse the HP in the water;

- on the HP, 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 movement of the HP to the place of entry into the oncoming course are calculated and transmitted to the control station;

- at the control station, commands are generated to guide the HP to the place of entry into the oncoming course along the estimated trajectory at the estimated speed and transmit them to the HP;

- on detachable torpedoes, their current coordinates and speeds are determined and transmitted through the HP and the control station to the ONS;

- in the ONS, after the HP enters the oncoming course, the trajectories and speeds of the HP and detachable torpedoes to the targets are calculated and transmitted to the control station;

- at the control station, commands are generated to point the HP at the target along the estimated trajectory with the estimated speed and transmit them to the HP;

- at the control station, commands are formed to separate torpedoes from the HP at the beginning of the calculated trajectories and transmit them to the HP;

- at the control station, guidance commands for torpedoes separated from HP are formed at the target along the calculated trajectories with calculated speeds and transmitted through the HP to the torpedoes.

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

ONS is similar to the known one (RU 2753498). The trajectory of the targets about which they maneuver is determined on the basis of an analysis of their actual trajectories. The place where the HP enters the oncoming course is chosen on the predicted continuation of the trajectory of the targets from the condition of providing the HP with time sufficient to separate the torpedoes and destroy the targets.

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

The place of immersion of the HP into the water is chosen from the condition of providing the HP 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 trajectories and speeds of movement of HP and torpedoes are calculated from the condition of preventing their collision with third-party objects and with each other, as well as from the condition of collision of torpedoes with targets at the required angles at the required speeds. The coordinates and sizes of third-party objects are determined in the hydroacoustic system and transferred to the ONS. After separating the torpedoes from the HP, the redistribution of targets between them is carried out by correcting their calculated trajectories and velocities.

The higher the speed of torpedoes, the higher their inertia and lower maneuverability. The ratio of speed and maneuverability for torpedoes in the final sections of the trajectories is optimized by setting the speeds necessary and sufficient to destroy targets in a collision.

Communication between the control station and HP and between HP and torpedoes, as well as monitoring the accuracy of targeting HP and torpedoes is carried out by known methods (RU 2730749). Due to the accurate determination of the coordinates and speeds of targets, homing heads on HP and torpedoes are not required.

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