Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following examples and accompanying drawings.

The energy-gathering follow-up killing warhead of the embodiment mainly comprises a warhead shell 1, a top-cutting liner 2, a warhead charge 3, a fuse 4, a follow-up ring 5, a pressure ring 6 and a prefabricated fragment 7. The top-cutting shaped charge liner 2 is arranged at the front end of the warhead shell 1, the warhead charge 3 is arranged between the warhead shell 1 and the top-cutting shaped charge liner 2, and the fuse 4 is arranged at the rear end of the warhead shell 1. Prefabricated fragments 7 are filled between the warhead charge 3 and the warhead shell 1 and between the following ring 5 and the truncated-cone-shaped cover 2. A follow-up ring 5 is arranged in the warhead shell 1, and the follow-up ring 5 is clamped at the front end of the truncated-cone-shaped cover 2 through a compression ring 6. The truncated-cone-shaped cover 2 is a truncated-cone-shaped shell, and is attached to the inner wall of the truncated-cone-shaped shell along with the feeding ring 5. The following ring 5 is provided with a strip-shaped notch 51, and the notch 51 is uniformly distributed along the circumferential direction of the following ring. The shape of the prefabricated fragments 7 can be one or the combination of a plurality of spheres, cylinders, cubic blocks and rhombohedrons.

The warhead shell 1 is a connecting part of the whole warhead, and the circumferential prefabricated fragments 7 are placed at corresponding positions through a die and fixed by special glue. The press-fit shaped warhead charge 3 is assembled to the warhead housing 1. The top-cutting shaped charge cover 2 and the following ring 5 are installed, when the top-cutting shaped charge cover is installed, the axis of the warhead charge 3, the axis of the warhead shell 1, the axis of the top-cutting shaped charge cover 2 and the axis of the following ring 5 are on the same straight line, then the top-cutting shaped charge cover is fixed by the pressing ring 6, when the pressing ring 6 is installed, silicon rubber is smeared around the threads to prevent the pressing ring 6 from loosening, and on the other hand, the front end of the warhead is sealed.
