Description

The invention relates to the field of military technology and can be used in ammunition, mainly in combat units of ground and air-based missiles.

Known technical solution according to US patent No. 6186072 dated February 22, 1999, F42B 12/06, according to which a penetrating projectile of contact operation is protected, the body of which is made of steel and has an axis of symmetry. The body has a nose and tail compartments. The payload is located in the tail section.

A technical solution is known according to the patent of the Russian Federation No. 2529122 dated 09/09/2013, F42B 12/04, according to which a penetrating warhead is protected, containing a massive body with a lid, where explosive filling is placed, a fuse is provided in the lid.

The aforementioned technical solutions do not ensure the detonation of the warhead at maximum contact with the object or inside the object.

A well-known design of a penetrating warhead (PrBCH) according to the patent of the Russian Federation No. 2277691 of 04/07/2005, F42B 12/04, containing a body, a bursting charge, an initiation system with a detonation delay.

The specified technical solution does not ensure the effective use of the design features of the munition and thus does not ensure the high efficiency of defeating specified targets.

A technical solution is known according to the patent of the Russian Federation No. 2344366 of 26.09.2007, F42B 15/00, according to which a penetrating warhead is protected, containing a cylindrical-conical equal-strength body filled with an explosive charge, an autonomous fuse device, consisting of an electrically connected safety-actuator, a target sensor, located in the housing and configured to determine the magnitude of the overload, while the power supply is installed on the bottom of the warhead housing, one of the contact damage sensors is installed on the outer conical surface of the front end of the warhead, and the second, inertial, inside the target sensor housing.

The above technical solution provides for making the body extremely strong (of equal strength in length) for penetration to the maximum (given) depth, which, like for the above analogues, implies restrictions on the mass of the explosive and, accordingly, on the effectiveness for a number of alternative purposes . The use of contact sensors located directly on the solid body of the penetrating warhead (PrBCH) limits the possibility of their operation when breaking through relatively thin obstacles; the use of inertial sensors located on the rear flange (cover) of the PFB does not guarantee operation during penetration, since the maximum overloads are realized at the beginning of this process, and also does not guarantee operation at meeting angles significantly greater than 90° (from the normal to the surface), when the lateral load can significantly exceed the axial. These shortcomings limit the combat effectiveness of warheads and the list of effectively hit targets.

The specified design of the PrBCh in terms of technical essence, the number of matching features and the achieved result is the closest analogue and is accepted as a prototype.

The objective of the present invention is to create a plug-in type PBCH of increased combat effectiveness in hitting a target.

The technical result to which the claimed invention is directed is to create a structure capable of realizing an effective undermining of the PBC with maximum contact with the object or inside the object.

The specified technical result is achieved by the fact that in the proposed technical solution:

- PrBCh predominantly insert type as part of the combat compartment, contains a body made in the form of an axisymmetric strong body with a head part of an ogive or conical shape and a cylindrical part with a bottom, an explosive charge, an explosive device containing an electromechanical fuse (EMF) with a detonation delay unit, contact sensors and housing destruction sensors;

- on the front of the body there is a plate bracket or several brackets along the cross-sectional line, on which contact sensors are placed, electrically connected to the electromechanical fuse,

- the destruction sensors are made of a tubular structure, with one end fixed inside the warhead on the rear bottom of the housing, so that the distance from the opposite end of the damage sensor to the point of intersection of the axis of the warhead with the inner surface of the housing, opposite the bottom, is 0.1-0.7 of the length of the inner housing cavity (L), a niche or grooves are made in the bottom from the outside and the destruction sensors are directly electrically connected to the fuse by cables placed in this niche or grooves;

A special case of design is the PBCH - on the poppet bracket between the contact sensors, radial grooves are provided with a depth of 0.3 to 1.0 of the thickness of the poppet bracket, which makes it possible to remove the poppet bracket when penetrating without loading and deforming the PBCh body.

A special case of the design is the PBCH to increase the efficiency of undermining - a deformable plate element is fixed on the housing plate in front of each contact sensor.

A special case of the design is the PBCH to increase the efficiency of undermining - a deformable plate is installed in front of the contact sensors in the head part of the compartment.

The greatest effective detonation of the PBC is achieved if a deformable plate element is fixed on the housing plate in front of each contact sensor or a plate is installed in front of the contact sensors in the head part of the compartment into which the PBC is inserted, with strength ensuring reliable operation of the contact sensors.

Distinctive features in a stable relationship of the entire set of essential features allow:

- to ensure the maximum use of the mass and volume of warheads in comparison with the prototype within the specified limits;

- to ensure the reliable functioning of the PBC;

- increase the efficiency of hitting targets due to the optimal choice of operation mode depending on the type of target and on the conditions of the meeting with the target.

According to the results of the analysis of the prior art, no analogues have been identified that have collectively features similar to the claimed solution. Therefore, we can assume that the claimed PrBCh is new and has an inventive step. Each of the above essential features is necessary, and their combination is sufficient to achieve the novelty of the quality of the new effect, which is not inherent in the features in their disunity.

The essence of the proposed technical solution is illustrated by drawings, where:

fig. 1 shows a longitudinal section of the PrBCh;

fig. 2 layout of deformable plate elements on the plate;

fig. 3 layout of the plate in the head part of the compartment.

fig. 4, fig. Figure 5 shows variants of the PBC with fracture sensors of various lengths.

The detachable-type PBCH as part of the combat compartment 11 contains a housing 1, an explosive charge from an explosive composition 2, an explosive device containing an electromechanical fuse (EMF) with a delay unit 3, contact sensors (KD) 4 and housing destruction sensors (DR) 5. The housing contains plate brackets 6, on which contact sensors 4 are placed, electrically connected with an electromechanical fuse. The plate brackets are located on the front part of the body, contain radial grooves 7 located between the contact sensors, the destruction sensors 5 are made of a tubular structure, one end is fixed on the bottom of the body, so that the distance from the opposite end of the damage sensor to the point of intersection of the axis of the warhead with the inner surface of the housing, opposite the bottom, is 0.1-0.7 of the length of the internal cavity of the housing.

Plate elements 8 (Fig. 2) can be provided on the housing plate in front of each contact sensor 4 or plate 9 in the combat compartment 10 in front of the contact sensors in the head part of the compartment 11 (Fig. 3), in which the PBC is inserted, with strength ensuring reliable activation of contact sensors.

When colliding with an obstacle, crushing, the compartment body closes CD 4. From the CD, the mechanism for counting the delay time (from 0 to 200 μs) is triggered by the EMW, after which the detonation of the RZ warhead is initiated from its output charge. Undermining the warhead, depending on the type of target, occurs inside the object of destruction (with a sufficiently large set delay) or near its surface (with a small delay), providing the maximum achievable degree of destruction. Warhead detonation occurs at the maximum achievable penetration depth.

When the CV meets a solid barrier or at large angles and high speed of the meeting, the hull of the warhead may be destroyed before the delay time expires. In this case, the EMW is triggered by the hull destruction sensors, which are closed when exposed to the deforming forces of the fragments of the collapsing hull directly or through the RZ explosive layer. The shorting of the sensors occurs when they are locally flattened, bent or stretched.

In the presence of deformable plate elements 8 on the plates or plates 9 of the carrier combat compartment, the reliability of the short circuit of the CD increases until the moment when, due to large deformation, the elements of the compartment body can damage the cables for connecting sensors with EMW.

In FIG. 4, fig. Figure 5 shows the variants of the PBC with damage sensors of various lengths:

fig. Fig. 4 shows a longitudinal section of the PBC, in which the distance from the end of the destruction sensor to the point of intersection of the axis of the warhead with the inner surface of the hull, opposite the bottom, is 0.1 of the length of the inner cavity of the hull;

fig. Fig. 5 shows a longitudinal section of the PBC, in which the distance from the end of the destruction sensor to the point of intersection of the axis of the warhead with the inner surface of the hull, opposite the bottom, is 0.7 of the length of the inner cavity of the hull.

The use of the proposed technical solution makes it possible to implement the high-explosive action (activation) of the PBC in the contact mode or in the penetration mode, optimized for the types of targets and for the conditions of the meeting with the target, thereby ensuring an increase in the efficiency of the use of ammunition.

Positive results of full-scale dynamic tests of the product developed according to the described scheme, as part of missiles, confirmed the operability and reliability of the PBC.
