Description

Technical Field

[0001] The invention belongs to the technical field of ammunition, and in particular relates to a chain kinetic energy striking device with high hit probability and low collateral damage. Background Art

[0002] Combat missions are no longer limited to large-scale destructive damage to targets. Small-scale and urbanized operations have become distinctive features of modern warfare. Cities are the most likely battlefields in the 21st century.

[0003] Urban warfare faces a special environment with dense populations, many buildings and crowds. Under the requirement of precise strike tactical objectives, the strike device needs to be able to accurately hit the target while effectively controlling the scope and degree of damage to prevent killing non-strike targets.

[0004] Existing strike devices use bullets to carry out point strikes on targets. The damage range is a line along which the bullet flies. The damage range is small and the target is easily missed. Alternatively, prefabricated fragments are used to carry out area strikes on targets. The damage range is a sphere of multiple flying fragments. The target is struck by the damage probability of the fragments. The strike range is large and people or objects outside the target may be struck indiscriminately.

[0005] Therefore, there is an urgent need for a chain kinetic strike device with high hit probability and low collateral damage to solve the problem that the strike device in the prior art cannot effectively control the damage range and strikes indiscriminately outside the target range.
