The fragmentation panel includes a fragmentation jacket, an explosive charge, a thin-walled shell and a detonator. The striking elements are used, made in the form of tetrahedrons from tungsten carbide powder (89-98% by weight, the rest is cobalt) by high-temperature vacuum-compression sintering followed by cobalt cladding. The geometric shape of the striking element is a tetrahedron, as the most acute-angled of the equilateral polyhedra.

The fragmentation panels are interconnected by a bracket in which a bursting pyroelectric element is built. The discontinuous pyroelement has an electrical connection with the control unit. The range finder installed in the bow of the UAV body is electrically connected to the control unit. The control unit provides for the issuance of a command to actuate the explosive pyroelement, followed by the transfer of the fragmentation unit to the combat position.

The use of a combat strike complex is as follows.

After launch, the operator of the control station, using the information received via the electrical communication line from the navigation system and the video camera, takes the complex into the combat zone to search for the target. When a target is detected, the operator switches on the attack mode on the control panel. After that, the control unit monitors the distance to the target according to the rangefinder readings via the electrical communication line, and at the appropriate moment, via the electrical communication line, gives a command to actuate a discontinuous pyroelement, which destroys the rigid connection between the panels of the combat element and transmits the primary impulse to open the fragmentation block from the body UAV. When the panels of the fragmentation block reach the combat position, the latch-switch fixes it, closing the electrical circuit for detonating the combat element. When a predetermined distance to the target is reached, the control unit gives a command over the electrical communication line to detonate the fragmentation unit and act on the target.

When the explosives of the fragmentation panel are detonated, the fragmentation jacket is divided into ready-made submunitions, which fly at the target at high speed, due to which the target is hit. 6 ill.

Description

Technical field

The utility model relates to military equipment and can be used in unmanned target destruction systems. Personnel, including those with personal protective equipment, as well as unarmored objects, including unmanned aerial vehicles (UAVs), are considered as targets.

State of the art

Known unmanned strike complex (RF patent 2558528). The unmanned strike complex contains an aircraft with a combat fragmentation element and is equipped with a control unit, a navigation system, a video camera, a rangefinder-target designator, the fragmentation unit is made in the form of two drop-down panels, each of which contains a body, a fragmentation jacket, an explosive and an electric detonator, moreover, the fragmentation panels blocks in the transport position are adjacent to each other with fragmentation jackets, and their bodies are the forming parts of the UAV fuselage, while one of the sides of each panel is connected to the UAV body by a hinge joint, and the opposite sides corresponding to them are mechanically connected to each other by a rigid connection made in the form an explosive pyroelectric element with a pyro-pusher having an electrical connection with the fragmentation munitions control unit. When undermined, the fragmentation block throws in the direction of flight a lot of ready-made submunitions made of VNM or VNZh alloy, made in the form of a sphere or a polyhedron close to a sphere.

The disadvantage of this complex are: insufficient damaging ability when acting on personnel equipped with personal protective equipment, the relatively high cost of striking elements due to the use of tungsten and nickel, the need to use a plate to prevent gas breakthrough between striking elements.

The objective of the proposed technical solution is to increase the lethality of an attack unmanned aerial vehicle by changing the design of the fragmentation jacket, changing the geometric shape of a separate striking element and using a new material for the manufacture of striking elements.

An additional objective of the proposed technical solution is to reduce the cost of finished submunitions and simplify the design of the fragmentation jacket.

In the process of solving the problem, a technical result is achieved, which consists in increasing the lethality of an attack unmanned aerial vehicle, reducing the cost of manufacturing striking elements and simplifying the design of a fragmentation jacket.

This technical result is achieved by using striking elements made of tungsten carbide powder (89-98% by weight, the rest is cobalt) by high-temperature vacuum compression sintering. At the same time, tungsten carbide powder can be obtained by recycling worn mining tools by the method of spark erosion. The geometric shape of the striking element is a tetrahedron, as the most acute-angled of the equilateral polyhedra.

After the manufacture of individual finished striking elements, a fragmentation jacket is formed and clad with cobalt. In the process of cladding, the bases of ready-made submunitions (tetrahedra) are interconnected to form a single surface.

Since, when laid in one layer, finished tetrahedral projectiles have a low fill factor (the ratio of the total volume of finished projectiles to the volume of the fragmentation jacket), the fragmentation panels are formed in such a way that in the transport position the fragmentation jackets partially penetrate each other with ready-made projectiles, thereby increasing the fill factor.

The figure 6 shows a diagram of the combat use of an attack unmanned aerial vehicle.

The strike unmanned aerial vehicle includes a body (1), in the central part of which a fragmentation block (2) is placed. The apparatus also contains a control unit (3), a video camera (4), a navigation system (5), and a range finder (6) placed in the fuselage. The fragmentation block (2) includes 2 fragmentation panels (7). The fragmentation panel includes a fragmentation jacket (8), an explosive charge (9), a thin-walled shell (13) and a detonator (10). The fragmentation panels (7) are connected to the UAV body (1) by hinges (14) through the axles (15), the fragmentation panels (7) are connected to each other by a bracket (11), into which a bursting pyroelement (12) is built. The discontinuous pyroelement (12) is electrically connected to the control unit (3). The rangefinder (6) installed in the forward part of the UAV body (1) is electrically connected to the control unit (3). The control unit (3) provides for the issuance of a command to actuate the explosive pyroelement (12) with the subsequent transfer of the fragmentation unit (2) to the combat position.

The use of a fragmentation block of an attack unmanned aerial vehicle is as follows.

After starting, the operator of the control station, using the information received via the electrical communication line (21, 22) from the navigation system (5) and the video camera (4), takes the complex into the combat zone to search for the target. When a target is detected, the operator switches on the attack mode on the control panel. After that, the control unit (3) monitors the distance to the target according to the indications of the range finder (6) via the electrical communication line (19) and at the appropriate moment via the electrical communication line (20) gives a command to actuate a discontinuous pyroelement (12), which destroys the rigid connection (11) between the panels (7) of the fragmentation block and gives the primary impulse to open the fragmentation panels (7) of the fragmentation block (2) from the body of the UAV (1). Disclosure of fragmentation panels (7) occurs due to the rotation of the hinges (14) around the axes (15) under the action of the oncoming air flow and springs (16). When the fragmentation panels (7) of the fragmentation block (2) reach the combat position, the locking devices (18) fix them, closing the electric circuit for detonating the fragmentation block. When a predetermined distance to the target is reached, the control unit (3) through the electrical communication line (23) gives a command to detonate the fragmentation unit (2) and act on the target.

When the explosive (9) of the fragmentation block (2) is detonated, the fragmentation jacket is divided into ready-made submunitions that hit the target, due to which the target is hit.
