Example Embodiment

[0029] Example one

[0030] Such as figure 1 As shown, this embodiment includes a spherical shell-shaped main explosive 4, a photosensitive explosive coating 3 coated on the outer surface of the spherical shell-shaped main explosive, and a strong light source arranged around the outer surface of the photosensitive explosive coating 3. The strong light source is an electric explosive device, including a metal wire 1.

[0031] The metal wire 1 undergoes an electric explosion under the action of a strong current to produce strong light 2, and the strong light 2 irradiates the photosensitive explosive coating 3 coated on the surface of the spherical shell-shaped main explosive 4, causing the entire surface of the photosensitive explosive coating 3 to explode at the same time. A detonation wave is generated to detonate the spherical shell-shaped main explosive 4, and the detonation wave propagates from the outer surface of the spherical shell-shaped main explosive 4 to the center of the...

Example Embodiment

[0032] Example two

[0033] The difference from the first embodiment is that this embodiment is also provided with a metal film / flyer 6 between the spherical shell-shaped main explosive 4 and the photosensitive explosive coating 3.

[0034] Such as figure 2 As shown, the metal wire 1 undergoes an electric explosion under the action of a strong current to generate strong light 2, and the strong light 2 irradiates the photosensitive explosive coating 3 coated on the surface of the metal film / flyer 6, so that the entire surface of the photosensitive explosive coating 3 is simultaneously An explosion occurs, and a detonation wave is generated to act on the metal film / flyer 6. Since the metal film / flyer 6 is in close contact with the spherical shell-shaped main explosive 4, the metal film / flyer 6 hits the spherical shell-shaped main explosive 4 to make it When an explosion occurs, a spherical detonation wave is formed to propagate from the outer surface of the spherical shell-shaped ma...

Example Embodiment

[0035] Example three

[0036] The difference from the first embodiment is that in this embodiment, a booster 7 is also provided between the spherical shell-shaped main explosive 4 and the photosensitive explosive coating 3.

[0037] Such as image 3 As shown, the metal wire 1 undergoes an electric explosion under the action of a strong current to generate strong light 2, and the strong light 2 irradiates the photosensitive explosive coating 3 coated on the surface of the booster 7, causing the entire surface of the photosensitive explosive coating 3 to explode at the same time , And generate a detonation wave to detonate the booster 7, which is close to the spherical shell-shaped main explosive 4. The detonation wave propagates through the booster 7 to the spherical shell-shaped main explosive 4, causing it to explode, forming a spherical explosion The blast wave propagates from the outer surface of the spherical shell-shaped main explosive 4 to the center of the sphere, and a shoc...

Abstract

The invention relates to a cohesive spherical wave generator, and solves the problem that the detonation synchronism of a traditional cohesive spherical wave generator is not easy to control. The cohesive spherical wave generator comprises a spherical housing-shaped main explosive, a photosensitive explosive and a strong light source, wherein the photosensitive explosive is coated on the outer surface of the spherical housing-shaped main explosive to form a photosensitive explosive coating; and the strong light source is arranged around the surface of the photosensitive explosive coating and is used for simultaneously detonating the photosensitive explosive coating. The cohesive spherical wave generator can realize large-area simultaneous detonation, can directly detonate the spherical main explosive by using the photosensitive explosive to generate cohesive spherical waves, and can also be used as a large-area synchronous detonation method to replace a detonation network.

Description

technical field [0001] The invention relates to a cohesive spherical wave generator, in particular to a cohesive spherical wave generator produced by explosive explosion. Background technique [0002] The cohesive spherical wave generator provides a loading method for cohesive spherical wave generation. Cohesive spherical wave refers to a detonation wave that propagates toward the center in a spherically symmetrical manner, and can generate extremely high temperature and pressure at the center of symmetry. Therefore, cohesive spherical wave is of great importance in engineering fields such as material synthesis and controlled thermonuclear fusion. Applications. It is usually composed of a hollow spherical explosive with a certain wall thickness. Place the research object such as the synthesized material near the center of symmetry. By detonating outside the spherical explosive, the detonation wave propagates along the radial direction of the explosive ball to the center of ...
