Description

The present invention relates to devices for marine underwater weapons.

Known deep-sea rocket bomb (RSL), including a warhead (warhead) with a fuse, a missile part (RF) with a rocket engine of solid fuel (RDTT) and a stabilizer [1]. The RSL is intended for the rapid delivery to the underwater target of a weapon, which is used as a depth bomb.

Known anti-submarine missile (PLR) 90P, including warhead, RF with solid propellant rocket and stabilizer [2]. PLR 90P is designed for quick delivery to an underwater target of a weapon, which is used as a gravity underwater projectile (GPS).

Known managed PLR, including a torpedo warhead, RF with solid propellant rocket and stabilizer [3]. Guided missile launcher is designed to quickly deliver to the underwater target weapons, which are used anti-submarine torpedo (PLT).

These devices have their drawbacks.

The disadvantage of RSL is the low probability of hitting a target.

The disadvantage of the 90R is the limited ability to maneuver when attacking an underwater target due to the lack of propulsion in the GPS.

The disadvantage of controlled PLR is that it provides an underwater target with the opportunity to detect in advance the operation of homing equipment of a PMT moving along a deepening spiral and to provide active fire and electronic countermeasures to it. In contrast to the torpedo warhead of the 90R guided missile launcher, the 90R rocket has a small response radius of the non-contact target detection system (NSO) and acts on the target from above, which significantly worsens the countermeasures for it. In the 2000s, the Swedish Navy developed the Alekto-type guided ballistic missile system, which uses the A-200 ultra-small torpedo (SMT) as a warhead, which has a small radius of action and vertical submersion, which eliminates these shortcomings [2], [4 ]. However, Alekto missile launcher also has a drawback - a limited operating time in the area of the splashdown and the termination of its functioning as it dives to the maximum depth similar to the GPS of a 90R rocket.

The aim of the invention is to develop a device that allows you to act in the area of the alleged location of the underwater target after splashing for quite a long time and attack the underwater target from above and from a distance that makes it difficult to use fire and electronic countermeasures, as well as inform your forces about the attack of the underwater target.

This goal is achieved due to the fact that, in contrast to the prototype PLR 90R device, including RF, stabilizer and warhead, which uses GPS, and the Alekto prototype device, which includes RF, stabilizer and warhead, which uses SMT , it is proposed to place an underwater projectile (PS) in the head of the rocket, a warhead separation mechanism with a remote device, a parachute, a buoy with a buoyer, a gas generator and a gun deepening mechanism, a self-liquidation mechanism, and, in an alternative design, a signal system with a radio transmitters are, cable and antenna and (or) the pistol; The PS is equipped with an explosive charge, the NSO of the target, operating in two modes: passive for primary detection of the target and active for its attack. The separation mechanism with a remote device serves to separate the missile and warheads before splashdown, the parachute - to ensure stabilization and braking of the PS in the air section of the trajectory until it is splashed, the buoy with a buoyer and a deepening mechanism - to set the PS to a given recess, self-destruction mechanism - for liquidation of the SS after a predetermined time, the signal system (in the variant version) - to transmit a signal about the detection and attack of an underwater target by radio and (or) a signal rocket. The possibility of multiple launch rocket launching of rocket launchers (RPS) from a launcher (launcher) allows for a short time to set up several RPS in the supposed location of the underwater target, when the alarm system is activated (in the variant version), it will receive information about the location of the target and its attack, in case of failure of the RPS to select it for further use or to liquidate the substation. An underwater projectile can be equipped with a propulsion device or use gravity to provide the required maneuver similar to GPS.

The compliance of the proposed technical solution with the criterion of "significant differences" is evidenced by the information given in table 1.

The proposed technical solution meets the criterion of "significant differences", since none of the distinguishing features in the known devices is not found.

Achieving a positive effect in the implementation of the proposed device is confirmed by the information given in table 2.

The technical implementation of the proposed method is illustrated by drawings, in which:

Figure 1 - General device RPS;

Figure 2 - the General structure of the head part of the RPS;

Figure 3 - the work of the RPS.

The essence of the proposed device is as follows.

Missile anti-submarine projectile (RPS) consists of three components (figure 1): stabilizer (1), missile part (2) and head part (3). Figure 2 shows the general structure of the head part of the RPM, which includes an underwater projectile (4), a warhead separation mechanism with a remote device (5), a parachute (6), a buoy with a buoyer, a gas generator, a deepening device, a self-liquidation mechanism and a signal system (optional) (7), container (8). The missile part and the stabilizer have a device similar to that of any other solid propellant rocket. Figure 3 shows the operation of the RPS, the numbers indicate: the movement of the RPS in the parachuting section (9), a buoy with a buoyer, a gas generator, a deepening device, a self-liquidation mechanism and a signaling system (in an optional version) (7) when the PS is deepened to a predetermined depth, the antenna signal system (10), a region of space examined by a non-contact target detection system of a PS (11).

RPS works as follows. Before the shot, the RPS is loaded into the launcher. RPS shot is carried out by applying an electric signal to the igniter igniter of the solid propellant rocket igniter. When the RPS approaches a predetermined point of the trajectory, a remote device is activated and sends a signal to the separation mechanism of the rocket and head parts, which are separated from each other, a parachute is pulled out and powered by the incoming air flow, the head part is brought down. After splashing the head part, a gas generator is activated, filling the buoy with compressed gas. A buoy under the influence of a positive buoyancy force pops up, unwinding the buoyer to a length corresponding to a given PS recess, the target NSO is switched on in passive mode, and the PS starts to work. After the underwater target is detected by the passive channel, the NSO active mode is activated, the alarm system (in the variant version) is triggered, the PS is separated from the buirep and the PS is guided to the target when the rudders are approached by the moment of approaching it by the value of the explosive device’s actuation and the target is hit by explosive PS. The signal system installed on the RPM in a variant execution notifies its forces of target detection and its attack by radio and (or) signal missile. If the PS does not work for a given time and the PS does not rise for further use, the self-liquidation mechanism is triggered, breaks the buoyerp and floods the PS.
