Description

The invention relates to explosive technology and can be used in explosive devices, including in cumulative warheads.

The prototype of the proposed technical solution selected cumulative warhead described in patent FR No. 3068456 from 04.01.2019

This cumulative warhead contains a housing, an explosive charge (explosive) placed in the housing, a cumulative lining connected to the explosive charge and the housing through the mount. In this case, the mount is a ring having a thrust surface for fixing the cumulative lining. The fixation of the cumulative lining is ensured by at least two wedges that are radially movable relative to the ring due to the use of a screw. The axial displacement of the screw having a conical head relative to the axis of the housing, while screwing it into the ring, results in a radial displacement of the wedge towards the housing, as a result of which all structural parts are locked and the cone is fixed.

The disadvantages of this design are:

- the use of radially movable wedges with a persistent conical surface that locks all structural parts makes it impossible to use this type of mount in thin-walled enclosures with a thickness of less than 2 mm, as well as in enclosures with a constant inner diameter due to the need to form a cumulative facing) conical surface;

- the location of the fastening elements in the zone of formation of the cumulative jet, which leads to the formation of a fragmentation field, which has a destructive effect on the cumulative jet at the time of its formation, and thereby reduces the level of the main characteristics of the product;

- the complexity of the manufacture and installation of parts involved in the compression of the cumulative lining.

These shortcomings lead to a decrease in the reliability of attachment of the cumulative cladding to the explosive charge and the warhead housing and, as a result, lead to a decrease in the effectiveness of the cumulative warhead.

The objective of the present invention is to increase the reliability of the attachment point of the cumulative lining, the exclusion of the attachment elements from the zone of formation of the cumulative jet, simplifying the design and assembly of the cumulative warhead.

The essence of the invention lies in the fact that a cumulative warhead is proposed, comprising a housing, an explosive charge placed in the housing, a cumulative lining connected to the explosive charge and the housing by means of an attachment unit, while new is that openings are evenly distributed in the side surface of the housing around the circumference, the mount is made in the form of two rings interacting with each other by means of a thread, the ring that contacts the inner surface of the housing is spring and split, and radial protrusions corresponding to the shape and size of the holes in the side surface are formed on its outer surface body, and in contact with them, while the second ring fixes the cumulative lining. The holes in the side surface of the housing are made in the form of windows of a rectangular shape, the larger side of which is parallel to a plane perpendicular to the longitudinal axis of the housing. Radial protrusions on the outer surface of the spring split ring are made at an equal distance from its ends in the form of annular sectors with a height equal to the wall thickness of the warhead body.

Also, a thread is made on the inner surface of the spring split ring, and an inclined conical surface is made on the inner side of the second ring, from the side of the cumulative cladding, forming an angle greater than 90 ° with the cladding surface, and a thread is made on its outer surface.

In addition, between the outer surface of the cumulative lining, the inner surface of the housing and the explosive is placed a gasket from a deformable material.

The invention is illustrated by drawings, FIG. 1, 2, where FIG. 1 is a longitudinal section of a cumulative warhead in the area of the attachment site of the cumulative lining, FIG. 2 is an enlarged view of a longitudinal section of the attachment point of the cumulative lining, made on the axis of the radial groove of the warhead.

The cumulative warhead contains:

1 - case;

2 - spring split ring with internal thread;

3 - cumulative lining;

4 - explosive;

5 - an internal ring with an external thread;

6 - radial protrusions on the outer surface of the spring split ring;

7 - holes in the housing;

8 - threaded connection of two rings;

9 - gasket from deformable material

The device operates as follows.

In the housing of the cumulative warhead 1, a spring split ring 2 is attached using radial protrusions 6, which are wound during assembly by compression into the side openings of the housing 7, uniformly distributed around the circumference. Further, an inner ring 5 is installed by means of a thread. Radial protrusions 6 are power structural members and perceive axial overload.

To exclude the possibility of radial displacement of the cumulative lining 3 relative to the axis of the warhead between the outer surface of the cumulative lining 3, the inner surface of the housing 1 and the explosive 4 is placed a gasket 9 of deformable material.

The dimensions of the spring split ring 2 and the ring with an external thread 5 are calculated so that between the cumulative lining 3 and the rings 2 and 5 connected by means of the threaded joint 8, at the initial moment of assembly there should be a gap of at least the allowance for extrusion (pressing) of the cumulative lining 3 together with explosive 4 in the housing 1 of the warhead.

Direct preloading of the cumulative lining by the ring eliminates the transitional fastening elements (ring, wedge, screw) from the structure, and thereby eliminates the details of the attachment site from the zone of formation of the cumulative jet.

As a result of the above design features, the cumulative warhead with the attachment point of the cumulative cladding to the explosive charge and to the hull has a high degree of reliability of fastening the cumulative cladding in thin-walled combat units without the use of protruding fastening elements that affect the formation of the cumulative jet and the stability of the armor-piercing cumulative combat parts.
