Description

The invention relates to missile weapons, namely to guided missiles of the class "ground-to-air" and "air-to-air". The device can be used to destroy all modern air attack weapons (targets), including low-flying anti-ship missiles, cruise missiles, operational-tactical ballistic missiles, UAVs, aircraft and helicopters.

A device for guided missiles of the "air-to-air" class for hitting air targets is known [L.L. Nelyubin. Illustrated military-technical dictionary. M .: Military Publishing House of the Ministry of Defense, 1968, p. 316], consisting of a radio fuse, electronic control equipment, a telescopic guidance and casting system for a warhead with explosives, located practically in the rear part of the rocket.

The disadvantage of this device is the low efficiency of the warhead.

The device is known for the combination of essential features closest to the invention and adopted as a prototype - ASTER anti-aircraft missile (Vladimir Korovin. NEW OPTIONS FOR ASTER Rocket. Magazine VKO, 2002, No. 2, (5) EUROSAM (prototype). The composition of the warhead of the rocket introduced two different types of fragments, previously directed towards the target.

The disadvantage of this device is the low efficiency of the warhead. Since the warhead is located in the middle part of the missile body, and when an explosive, even a special form, is detonated, the fragments fly apart in different directions, forming a cloud similar in shape to a torus. With this method of hitting air targets, a quarter of the fragments is involved in the defeat at best, and therefore the mass of the warhead will be heavy. The fragments with such an expansion have a low kinetic energy, which requires a minimum distance to the target.

The objective of the invention is to increase the effectiveness of destruction of air attack equipment.

The problem is solved by replacing the fragments with a missile body, which is fired accurately from the trunks surrounding the instrument compartment at a distance that ensures maximum hit. When fired, a missile body acquires great kinetic energy and is capable of hitting any air targets as much as possible. To accurately determine the moment of a shot, a mathematical image of the target and its speed are introduced into the on-board computer (BEM) before launching the rocket.

Other advantages will be apparent from the description of the invention and the drawings, in which Fig. 1 shows a general view of the device and a control circuit, and Fig. 2 shows a front view.

Figure 1 shows a General view of the device and the control circuit, which contains the instrument compartment 1, protected from the front with an optical glass 2, inside the compartment there is a photodetector 3, an image converter 4 into a digital code, a computer 5, additional memory (RAM) 6, a laser rangefinder 7, switch on the electrocapsule 8. Around the instrument compartment 1 there are trunks 10 fastened together and made of metal or high-strength composite polymer, which are simultaneously the body of the rocket 13, the capsule 9. Inside the barrel la is powder 11, methane body 12 in the form of bullets for the breakdown of the rifled barrel or nucleus with incendiary or explosive action for a smooth bore.

The device works as follows: before launching the rocket, the optimal distance for launching the electrocapsule 9, the mathematical model of the target’s image and the possibility of its flight (linear speed and possible maneuvering) are recorded in memory 6, this allows to increase the noise immunity of the device. During the flight of the rocket, the target image through optical glass 2 enters the photodetector 3, the received image of the target is converted to a digital code by the converter 4 and fed to the BEM 5, where the signal is compared with the mathematical model of the target image in memory 6. At the same time, the signal from the laser is transmitted to the computer rangefinder 7, if the obtained parameters coincide with the given accuracy, the distance to the target and the image of the target in digital code, with the parameters stored in memory 6, the computer 5 generates a signal to the switching device 8, which e supplies voltage to the electrocapsule 9. When igniting the powder 11 from the electrocapsule 9, the combustion products accelerate the propelled body 12 in the barrel 10 to a speed close to 1000 m / s. Given that the velocity vector of the missile and the missile body are the same, the energy of the missile body will be enough to hit ground armored targets.
