Problems solved by technology

At present, the industry standard "Safety Code for Design of Gunpowder, Explosives, Ammunition, Fuze and Explosive Products Factory" adopted by our country uniformly stipulates the safety distance as 850m, without considering the different types of fragment warheads and the particularity of various explosion accident states. A certain degree of scientificity and rationality, resulting in waste of land resources and unnecessary security protection costs

Abstract

The invention provides a prefabricated fragment warhead safety distance prediction method and related equipment. The method comprises the steps that the fragment critical speed is calculated accordingto effective fragment energy of a prefabricated fragment warhead; calculating a first fragment critical distance of the prefabricated fragment battle according to the fragment critical speed; calculating a second fragment critical distance of the prefabricated fragment warhead according to the fragment critical surface density of the prefabricated fragment warhead; and determining the smaller value of the first fragment critical distance and the second fragment critical distance, and taking the smaller value as the fragment safety distance of the prefabricated fragment warhead. According to the method, the fragment safety distance of the prefabricated fragment warhead can be quickly and accurately predicted.

Description

technical field [0001] The invention relates to fragment warhead technology, in particular to a method for predicting the safe distance of a prefabricated fragment warhead and related equipment. Background technique [0002] The prefabricated fragment warhead is a weapon type widely used in the military. The pre-controlled fragmentation adopts technical measures such as notching the shell, notching the explosive, or increasing the inner lining to weaken the local strength of the shell and control the rupture site during the explosion, thereby forming fragments. The characteristic of the prefabricated fragment warhead is that the formed fragments are uniform in size and basically regular in shape. [0003] The safe protection distance of the warhead is an important protection index in the process of building a military arsenal, storing and destroying ammunition. At present, the industry standard "Safety Code for Design of Gunpowder, Explosives, Ammunition, Fuze and Explosiv...
