Description

Technical Field

[0001] The utility model belongs to the technical field of two-stage series warheads of ammunition, and particularly relates to a delayed detonation transmission structure suitable for two-stage series warheads. Background Art

[0002] Tandem warheads are constantly improved according to different military objectives. Tandem warheads mainly include breaking-penetrating tandem warheads and breaking-breaking tandem warheads. When conducting research on tandem follow-up warheads, no matter which type of tandem warhead, the research on the delayed detonation technology of two-stage tandem warheads is very important.

[0003] At present, the main way to achieve the delayed detonation function between two-stage tandem warheads is to use a single fuze plus a delayed detonation structure. By adopting a suitable delayed detonation structure and configuring a reasonable delay time, the destructive power of the main warhead on military targets can be guaranteed.

[0004] The design of the delayed detonation transmission structure, where the delay cord and warhead charge are assembled, typically incorporates a cable slot into the cylindrical side of the warhead charge. During the delayed detonation transmission process, the delay cord generates a detonation wave that impacts the warhead charge and, in turn, reduces the warhead's power. Therefore, the design of the delayed detonation transmission structure must consider the impact of the delay cord on the warhead charge and mitigate the effects of the delay cord's detonation on the warhead charge. To this end, a small steel tube with sufficient strength to protect the delay cord from damage is typically selected. During assembly of the delay cord and warhead, the delay cord is threaded through the small tube to mitigate the effects of the detonation on the warhead charge. This method effectively mitigates the effects of the delay cord's detonation on the warhead charge. However, due to the warhead's structural design, the small tube often has multiple bends, and the delay cord often suffers unobservable damage during assembly, leading to failure of the delayed detonation transmission structure and, ultimately, the weapon system.
