Explosion self-destruction device for cylinder test

Abstract

The invention provides an explosion self-destruction device for a cylinder test. The device comprises an exploder, a detonator A, a self-destruction main body device, a metal partition plate and a detonating cord. The self-destruction main body device is composed of a shell, a self-destruction explosive and a shaped charge liner. One end of a main charge is provided with a 45-degree shaped chargewhich is attached to the shaped charge liner and installed in the shell, a detonator hole is reserved in the other end of the main charge, and the detonator A is inserted into the detonator hole of the self-destruction explosive. A detonating hole is formed in the center of the side wall of the shell and is connected with a booster end of the detonating cord. The included angle between the metal partition plate and a cylinder test charge axial center line is 45 degrees, a detonation hole with the diameter of 10 mm is formed in the center of the metal partition plate, and a detonation end is installed. The explosion self-destruction device is added, and test data of the cylinder test is not influenced. After normal detonation in the cylinder test, the explosion self-destruction device is normally exploded, and no charge is left. After abnormal detonation in the cylinder test, the explosion self-destruction device can self-destroy the cylinder test filled with casting-type insensitive explosives.

Description

technical field [0001] The invention belongs to the field of propellants and explosives, and relates to an explosive self-destruct device, in particular to an explosive self-destruct device used for cylinder tests. Background technique [0002] The cylinder test is a test to determine the energy release and ability of the detonation product to accelerate against a metallic copper wall as it expands. Under the stimulation of the detonation energy provided by the detonation system, the tested explosive ignites and grows to a detonation state, and at the same time works on the metal copper wall to drive the fragments to move. During the test, changes in the external environment, especially external energy stimuli, will interfere with the test results and affect test accuracy. Excessive detonation energy will lead to high test results, so the detonation energy is required to be slightly higher than the critical detonation threshold of the tested explosive. Due to the limitatio...
