Problems solved by technology

However, although the fragment protection unit composed of ceramic / light metal enhances the anti-penetration ability, it does not consider the impact of the air shock wave on the survival time of the ceramic, and does not consider the impact of the fragment group on the asynchronous strike of the ceramic on its anti-penetration performance.

Abstract

The invention discloses an X-ray radiography window protection structure of a blasting vessel. The structure is applied to a window passageway and comprises an air impact wave protection unit, a fragment protection unit and a sealing unit. The air impact wave protection unit is fixed to the inner side of the window passageway. The fragment protection unit is fixed into the window passageway. The sealing unit is fixed to the outer side of the window passageway and located on the outer side of the fragment protection unit. The structure can effectively attenuate air impact waves, the penetration resistance of the structure can be improved, and the advantages of all the protection units are effectively brought into play; meanwhile, the areal density of the structure is lower than that of an aluminum alloy protection structure, and permeability of X-rays is promoted.

Description

technical field [0001] The invention relates to the technical field of X-ray photographic window protection for explosion containers, in particular to a ceramic / aluminum alloy composite protection structure capable of resisting combined effects of air shock waves and high-speed fragment groups. Background technique [0002] It is an effective diagnostic method in the design and research of weapons to conduct X-ray photography experiments with explosive containers. In order to protect the flash machine and the film from the damage of the air shock wave and the high-speed fragment group, the photographic window of the explosion container needs to have a special protective structure. The protective structure of the photo window must first meet the requirements of X-ray permeability, that is, the surface density should be low, and the atomic number of the material should be as small as possible; secondly, it should be able to resist the combined damage of air shock waves and hig...
