RU2775181C1 - Method for underwater target destruction by torpedoes separated from carrier torpedo - Google Patents

Abstract

FIELD: missile and torpedo guidance systems.

SUBSTANCE: invention relates to missile and torpedo guidance systems. In the hydroacoustic system, underwater targets are detected and tracked, the coordinates, speeds and characteristics of the targets are determined and transmitted to the defensive-offensive system (DOS), where a missile with a torpedo carrier or a torpedo carrier is assigned and their data is transmitted to the control station, where the missile is launched or torpedo carrier. On the missile, its coordinates and speed are determined and transmitted through the control station to the DOS, where the coordinates of the place where the torpedo-carrier is immersed in water are determined, the trajectory and flight speed of the missile to the specified place are calculated and transmitted to the control station, where the missile guidance commands and the command for separating the torpedo-carrier from the missile are formed and transmitted to the missile. On the carrier torpedo, if the targets are under the ice, the ice thickness is surmounted and the carrier torpedo is immersed in water, its coordinates and speed are determined and transmitted through the control station to the DOS. On torpedoes separated from the carrier torpedo, their coordinates and speeds are determined and transmitted through the carrier torpedo and control station to the DOS, where the trajectories and speeds of the carrier torpedo and detachable torpedoes to targets are calculated and transmitted to the control station, where they are formed guidance commands for the carrier torpedo and commands for separating torpedoes from the carrier torpedo and transmit them to the carrier torpedo. Commands for guiding torpedoes separated from the carrier torpedo are formed at the control station and transmitted through the carrier torpedo to the torpedoes.

EFFECT: method provides an increase in the probability of destruction of underwater targets by torpedoes.

Description

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

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

However, such methods do not provide: - the ability to determine the number of targets in a group and their characteristics before launching a torpedo carrier; - 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; - the possibility of destroying targets under the ice, since they do not provide for overcoming the thickness of the ice; - 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 underwater targets with torpedoes.

The proposed method is that:

- in the hydroacoustic system, underwater targets are detected and tracked, the current coordinates, speeds and characteristics of the targets are determined and transmitted to the defensive-offensive system (ONS);

- in the ONS, a rocket with a torpedo launcher or a torpedo launcher is assigned and their data is transmitted to the control station;

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

- at the control station, the designated rocket or torpedo launcher is launched;

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

- in the ONS determine the coordinates of the place of immersion of the torpedo-carrier into the water, and also calculate the trajectory and speed of the missile to the specified place and transmit them to the control station;

- at the control station, commands are formed to guide the missile along the estimated trajectory at the estimated speed and transmit them to the missile;

- at the control station, a team is formed to separate the torpedo-carrier from the rocket and transmit it to the rocket;

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

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

- on torpedoes separated from the carrier torpedo, their current coordinates and speeds are determined and transmitted through the carrier torpedo and control station to the ONS;

- in the ONS, the trajectories and speeds of the carrier torpedo and detachable torpedoes to the targets are calculated and transmitted to the control station;

- at the control station, commands are formed to guide the torpedo-carrier along the estimated trajectory at the estimated speed and transmit them to the torpedo-carrier;

- commands for separating torpedoes from the carrier torpedo are formed at the control station and transmitted to the carrier torpedo;

- at the control station, guidance commands for torpedoes separated from the carrier torpedo are formed,

along the calculated trajectories with the calculated speeds and transmit them through the carrier torpedo to the torpedoes.

The hydroacoustic system is similar to the known one (iz.ru/news/647107). 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). Rocket, launcher torpedo and torpedoes are assigned based on their effectiveness. On a rocket, launch vehicle and torpedoes, their coordinates and speeds are determined using onboard inertial navigation systems corrected using a global satellite navigation system.

The coordinates of the place of immersion of the torpedo-carrier into the water are determined from the condition of bringing the torpedo-carrier into a collision course with the targets. The trajectory and speed of the missile 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 command for separating the torpedo-carrier from the rocket is formed at the end of the estimated trajectory of the rocket. Overcoming the thickness of the ice and immersion of the torpedo-carrier in the water is carried out in a known manner (RU 2707233).

The trajectories and speeds of the carrier torpedo 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 effectively hitting targets in accordance with their characteristics. Commands for separating torpedoes from the carrier torpedo are formed at the beginning of the calculated torpedo trajectories.

The connection between the carrier torpedo and the control station and between the carrier torpedo and torpedoes, as well as the control of the guidance accuracy of the carrier torpedo 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 torpedoes 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 station; 4 - rocket with a torpedo carrier; 5 - torpedo carrier with detachable torpedoes; 6 - torpedoes separated from the carrier torpedo.

Connections between blocks: 1-2 - current coordinates, speeds and characteristics of underwater targets; 2-3 - data of the assigned missile with a torpedo-carrier or a torpedo-carrier, the estimated trajectory and speed of the rocket to the place of separation of the torpedo-carrier from it, as well as the calculated trajectories and speeds of the torpedo-carrier and detachable torpedoes to the targets; 3-2 - current coordinates and velocities of the missile, carrier torpedo and detachable torpedoes; 3-4 - commands for guiding the missile along the estimated trajectory at the estimated speed, as well as the command for separating the torpedo-carrier from the missile; 3-5 - instructions for guiding a torpedo-carrier along a calculated trajectory with a calculated speed, commands for separating torpedoes from a torpedo-carrier, as well as commands for guiding torpedoes separated from a torpedo-carrier along calculated trajectories with calculated velocities; 4-3 - current coordinates and speed of the rocket; 5-3 - current coordinates and speeds of the carrier torpedo and detachable torpedoes; 5-6 - guidance commands for torpedoes separated from the carrier torpedo along the calculated trajectories with the calculated speeds; 6-5 - current coordinates and speeds of torpedoes separated from the carrier torpedo.
