Description

The described invention relates to methods for hitting targets with anti-submarine missiles.

The armament of surface ships and submarines of leading sea powers consist of ballistic and cruise anti-submarine guided missiles [1, p. 356-361].

The ballistic anti-submarine missiles (ASL) Asrok (USA), Medvedka (Russia), the winged ASMs Milas (France), Icarus and Super Icarus (Great Britain), 85P and 85RU (USSR) are known. As the warhead of these missiles use anti-submarine small-sized torpedoes (MGT) [2].

Reliable target designation is required to ensure firing of PLR, especially when firing at long distances. At the same time, shipboard sonar aids for detecting underwater targets have a complex configuration of observation zones with numerous “shadow” zones, depending on hydrology and depths in the area. The presence of shadow zones creates the prerequisites for skipping the target and the flight of the PCR on the trajectory [1, p. 359].

This drawback can be eliminated by choosing the option of a cruise anti-submarine missile having a flat trajectory with a small marching height of up to 10-20 m or equipping the missile launcher with means for detecting an immersed submarine, for example, a magnetometer, and devices for preventing (compensating) missed missile (flight) [ 1, p. 328-336], [3].

Magnetometric detection tools (aviation search magnetometers) are placed on the winged RLP as a means of detecting a submerged submarine (PL) [3]. A low-flying winged PLR having a flat trajectory with a small marching height of the order of 5 ... 10 m (to increase the depth of target search) [4, p. 107], equipped with a magnetometer, makes it possible to exclude missed submarine targets with an immersion depth of up to 500-600 m along the trajectory (flight PLR) and to separate the torpedo warhead at the detection point of the submarine. The immersion depths of modern submarines do not exceed 600 m, which ensures their reliable detection by a magnetometer located on a winged low-flying submarine. After splashdown, torpedo warheads of the PLR perform a circular search of the PL target using acoustic homing equipment (ASN). With a range of ASN of the order of several kilometers, reliable secondary detection and destruction of a submarine target by a torpedo is provided.

A known method of using an anti-submarine missile equipped with a magnetometer and corresponding additional devices providing target detection and control of the missile on the trajectory, which consists in the fact that after launching the missile, it is held at a low marching altitude, the magnetometer is turned on at the calculated point and the target is searched for, with detection targets to indicate its location are dropped from a rocket marker or a radio sonar buoy (RSL), as well as a torpedo, if it falls into the target capture area with its self-propelled equipment reference [3]. If torpedoes do not fall into this area, deploy the rocket to the opposite course and drop the torpedo at the point marked with a marker or RSL, search for the target with a torpedo, find it and carry out an attack by moving the torpedo closer to the distance of its proximity fuse or until the torpedo collides with target body, after which they undermine the explosive of the warhead of the torpedo and hit the target [3].

The disadvantage of this method is that, after detecting a target, a missile defense system can quickly leave the target capture area by a torpedo homing system, especially when flying at a high (supersonic) speed, and miss the target. This circumstance is due to the fact that when a rocket is flying at low altitude and at high speed, in order to ensure braking of a torpedo before its landing, it is necessary to drop a torpedo on a climb trajectory (cabling maneuver). This maneuver may take some time for the rocket to move away from the target by a distance exceeding the response radius of its homing equipment. The missile’s turn and the performance of torpedo throwing on a second approach gives the target additional time and the ability to counter.

So, for example, the minimum radius of a rocket’s turn r _min is determined by the formula [5, p. 138]:

where V is the velocity of the rocket, m / s; g is the acceleration of gravity; n _{p max} - the maximum possible overload of the rocket, which is its dynamic characteristic of maneuverability.

Given the known formulas for the calculation of the circumference and travel time along it: L = 2πr _min and t = L / V, while full reversal rocket embodiment when there is circulation of the formula:

When the rocket speed is V = 500 m / s and n _{p max} = 10, the minimum radius of the rocket’s turn will be r _min = 2548 m, the circumference described by the rocket for the second call to the location of the previously discovered target is L = 16012 m, the time the rocket will complete circulation t = 32 s. For 32 s, the target will move away from its previous location at a fairly large distance and will have the additional opportunity to counter the attacking rocket.

The aim of the invention is to develop a method of hitting a submarine with an anti-submarine cruise missile having a high speed and low altitude, which would provide an attack of the target from the first approach without rocket circulation.

This goal is achieved due to the fact that, in contrast to the prototype method, after the target is detected by a magnetometer, the coordinates of the target are fixed and entered into the torpedo control system, the coordinates of the torpedo’s landing point and the route of its movement to the target after the landing are calculated in the calculating and deciding device, control the movement of the torpedo to the point of location of the detected target.

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 device is not detected.

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

The proposed method of hitting a target with an anti-submarine cruise missile will make it possible to eliminate missile flying past the target in cases of an enemy submarine entering shaded areas of hydroacoustic detection and target designation, using magnetometric means of detection, as well as to eliminate the need to turn the missile to the opposite direction to prevent torpedo landing outside areas of target capture by its homing system when flying a rocket at low altitudes and high speeds.
