Problems solved by technology

For traditional shaped charges, see figure 1 As shown, in order to increase the penetration aperture, a liner with a large cone angle or a spherical segment liner is often used, but the jet velocity formed is often lower than that of a small cone angle, and the penetration depth is smaller

Embodiment Construction

[0013] see Figure 2-Figure 3 , a shaped charge structure that can increase the penetration speed, including a detonator 1, an explosive 2, a cavity 3 and a charge cover 4. The cavity 3 is located on the central axis of the charge, and is spherical with a radius of R. The overall size of the shaped charge is φ×H. The size of the mouth of the drug-shaped cover 4 is C, and the height is B. The distance between the lower part of the cavity 3 and the charge is Cover 4 top is A. When H=(1.2~1.5)φ, the size and position relationship of the hole 3 satisfies: R=(1 / 9~1 / 7)φ, R=(0.4~0.6)A, the penetration speed can be effectively improved, At the same time, the penetration hole diameter is not reduced.

[0014] The charging method is explained step by step as follows:

[0015] a) When the press-packing process is used to charge the powder, the following sub-steps are included:

[0016] Sub-step 1: Make the spherical mold 6 for the hollow ball 3, and make the shell mold for the upper ...

Abstract

The invention relates to a charge structure for improving the shaped charge penetration speed. The charge structure comprises a detonator, an explosive column and an explosive-shaped cover, one end ofthe explosive column is connected with the detonator, the other end of the explosive column is provided with the explosive-shaped cover, and the axes of the detonator, the explosive column and the explosive-shaped cover coincide with one another; and a hole ball is further arranged on the explosive column, the interior of the hole ball is air, and the sphere center is located on the central axisof the explosive column and is close to the top end of the explosive-shaped cover. According to the charge structure for improving the shaped charge penetration speed, the large penetration hole diameter is achieved, moreover, the penetration depth can also be improved, on the basis of existing large-penetration-hole-diameter shaped charge, the penetration speed can be improved by 15% or above under the condition that the penetration hole diameter is not reduced, the charge energy utilization rate is high, and the wide applicability is achieved.

Description

technical field [0001] The invention relates to a novel shaped-energy charging structure capable of increasing the penetration speed of the shaped-energy. Background technique [0002] The use of concentrated charge technology to penetrate or penetrate targets or structures has been widely used in national defense and civilian industries. Often under the constraints of limited charge space size, it is necessary to ensure sufficient penetration aperture, It also needs to have sufficient penetration, which puts forward higher requirements for the design of shaped charges. For traditional shaped charges, see figure 1 As shown, in order to increase the penetration aperture, a liner with a large cone angle or a spherical segment liner is often used, but the formed jet velocity is often lower than that of a small cone angle, and the penetration depth is smaller. Contents of the invention [0003] The technical problem solved by the present invention is: in order to solve this ...
