Description

The invention relates to the field of rocket technology, namely to guided missiles of multi-purpose.

Known fragmentation-projectile shell "Otroch" penetrating action, containing a multipurpose high-explosive fragmentation warhead, providing both axial and circular fields of destruction, containing a body with a solid head part with a charge of explosive and a fragmentation block located in front of the explosive charge, a detonator, located in the middle part of the explosive charge, a trajectory-contact head fuse electrically connected to the detonator.

The head part of the body is made of thin-walled, conical or animated shape, the fragmentation block covers the head part of the monolithic body from the outside, while the fuse is electronic, and the detonator is equipped with a safety mechanism and an adjustable deceleration unit.

The design flaws include insufficient separation of the fragmentation block and the monolithic shell of the warhead filled with explosive, which cannot ensure the effectiveness of the axial and circular fragmentation action when the monolithic shell penetrates into the barrier due to the destruction of the fragmentation block enclosed in a thin-walled shell when meeting with an obstacle for any given deceleration range (Patent RU 2327948C2, F42B 12/32 of 06/27/08)

Known guided missile, selected as a prototype, containing a tandem warhead, hardware compartment, steering gear unit located in the head compartment, electronic delay unit, a retractable device with a leading cumulative warhead mounted on its front end, while the rear end of the device is located in a conical cavity formed by a cumulative funnel of the main warhead (RF Patent No. 2084809, F42B 12/18 from 07.20.97)

The presence of a retractable device in the design of the guided missile ensures the safety of the main warhead when exposed to detonation products and fragments at the time of undermining the leading cumulative charge and the effectiveness of the main warhead by increasing the focal length to the obstacle.

The disadvantages of the design of a guided missile with a tandem cumulative warhead include the absence of a fragmentation unit, which limits its scope in modern combat.

It becomes expedient to equip guided missiles with a retractable device and the leading cumulative charge of a fragmentation warhead placed on its front end, which will ensure their multifunctionality and the ability to use it for hitting lightly armored targets and manpower.

The objective of the present invention is to provide a multi-purpose guided missile for multifunctional purposes to destroy lightly armored targets and manpower in shelters and in open areas.

This is achieved due to the fact that in a guided missile containing a tandem warhead, a head compartment with a steering gear unit, an equipment compartment, an electronic delay unit and a retractable device, in the front of which a cumulative warhead with a fuse, a marching rocket engine is installed, between a high-explosive fragmentation warhead with a safety-executive mechanism, the body of which is made cylindrical, in the form of an all-metal th shell, inside of which with a ring gap relative to the inner surface of the cylindrical part of the shell a plastic sleeve is installed, resting on an annular stop, which is made in the transition zone of the cylindrical part of the body into a conical part, an injection explosive charge is placed inside the plastic sleeve, the gap is filled with ready-made striking elements, at the same time, in the front part of the injection charge of the explosive, an axisymmetric conical recess closed with a plastic casing is made, facing voim base to the head projectile compartment in which is placed a shot until the rear part of the drawer and the rear of the charge injection performed with coaxial cylindrical undercut arranged therein detonation pulse amplifier as a high-checkers composition.

This technical solution is illustrated by graphic materials.

Figure 1 shows the cross section of a guided multi-purpose missile in the initial position (before the shot), Figure 2 - in the working position, Figure 3 is a cross section of a high-explosive fragmentation warhead.

The guided missile contains a head compartment 1 with a placed steering gear unit 2, a hardware compartment 3, a retractable device 4, a cumulative warhead 5 with a fuse 6, a main rocket engine 7, a high-explosive fragmentation warhead 8 with an electronic delay unit, located on its front end 9, the body of which is cylindrical in the form of an all-metal shell 10, inside of which a thin-walled plastic sleeve 11 is installed, filled with an injection charge of explosive 12 and installed with a ring th gap relative to the inner surface of the cylindrical portion of the shell on an annular abutment 20 formed in the transition zone of the cylindrical body portion into a conical. Inside the annular gap placed ready damaging elements 13.

In the front part of the injection charge of the explosive, an axisymmetric conical recess 15 is closed with a plastic casing 14 to accommodate the rear of the drawer 4, facing its base to the head compartment 1.

In the rear part of the injection charge of the explosive, facing the safety-actuating mechanism 18, a coaxial cylindrical undercut 16 is made with a detonation pulse amplifier placed in it in the form of a high-energy composition checker 17. In the particular case, the finished striking elements are made in the form of metal balls.

The proposed design works as follows.

At the time of the shot, the retractable device 4 with a cumulative warhead 5 installed in its front part with a contact fuse 6, for example, is moved forward inside the head compartment 1 and is fixed in it due to the pulsed pyrotechnic device.

Upon encountering an obstacle, a contact action fuse 6 of a cumulative warhead 5 is fired, and a lightly armored obstacle is destroyed by a cumulative stream with the formation of a hole. The effectiveness of the defeat depends on the overall dimensions of the cumulative warhead.

The presence in the design of the projectile of the electronic delay unit 9 ensures the subsequent operation of the explosive charge of the high-explosive fragmentation warhead 8 with a delay of 300 ÷ 400 μs and the destruction of the all-metal casing of the high-explosive fragmentation warhead at the moment determined by the strength characteristics of its shell, which excludes the possibility of exposure to detonation products formed during the detonation of a cumulative warhead to the fragmentation zone, and therefore leads to increased effectiveness of the defeat. In this case, a block of striking elements occurs, made in the form of one or two layers of striking elements 13, placed in an annular gap formed by a thin-walled plastic clip 11 of the injection charge of the explosive 12 and the inner surface of the cylindrical part of the all-metal shell of a high-explosive fragmentation warhead 10.

The diversity of the fragmentation unit and the cumulative warhead provided for by the design of the multi-purpose guided missile ensures the detonation of the high-explosive fragmentation warhead until its hull parts approach the obstacle, which ensures the effectiveness of the destruction of manpower by the fragmentation field of the finished striking elements.

The implementation of the block ready-made striking elements in the form of metal balls is due to the requirements of manufacturability of the assembly and reduce the cost of construction of a high-explosive fragmentation warhead. It is possible to fill the annular gap between the all-metal shell of the high-explosive fragmentation warhead case and the plastic shell of the explosive charge of the explosive with inserted striking elements in the form of wedges or cubes, while maintaining the weight characteristics of the warhead.

The implementation of coaxial cylindrical undercut 16 at the rear of the injection charge of an explosive of a high-explosive fragmentation warhead with a high excitation pressure is caused by the need to place a detonation pulse amplifier 17 in it in the form of a high-energy composition checker with a low excitation pressure facing the transfer hole of the safety-shutter damper 19 mechanism 18 in its working position, which ensures an undamped detonation wave inside the injection charge with very weak initiating ability.

Thus, the proposed technical solution allows you to create a multi-purpose guided missile for hitting lightly armored targets and manpower in shelters and in open areas using standardized guided missile shells with a tandem cumulative warhead, such as a head compartment with a retractable device, a leading hardware compartment cumulative charge, sustainer rocket engine, steering unit, electronic delay unit, etc., while maintaining the center of mass and weight x characteristics of the projectile, which will expand the scope of guided projectiles in modern combat.
