Controlled fragment with warhead shell function

Abstract

The invention discloses a prefabricated fragment with the function of a warhead shell. The warhead shell includes a powder column, a conical protective cover and a seal at the tail of the powder column. A cylindrical prefabricated fragment is arranged outside the powder column. The inner and outer surfaces of the prefabricated fragments are equidistantly and longitudinally divided into partition grooves, and the middle is a solid structure; the prefabricated fragments are divided into multiple partitions by the partition grooves; and the two ends of the partitions are streamlined. The advantages of the present invention are that it effectively increases the stress of the grain on the prefabricated fragments, reduces the speed loss during the flight of the partition body, increases the kinetic energy to reach the target point, has strong penetration ability to the target, and increases the speed of the partition body. effectiveness.

Description

technical field [0001] The invention relates to a prefabricated fragment with the function of a warhead shell. Background technique [0002] Currently as Figure 4 The structure of the prefabricated fragment warhead shown is that a steel structure casing is provided around the grain, and prefabricated fragments are arranged on the inside or outside of the steel structure casing; in this way, after the explosion of the grain, part of the force is used to push away the steel structure casing, and the other part acts on the prefabricated fragments. The stress on the prefabricated fragment is relatively reduced, which affects its destructive force when it reaches the target. At the same time, when the explosive column explodes, the steel shell fragments will affect the flight speed and flight trajectory of the prefabricated fragments, seriously affecting the effectiveness of the prefabricated fragments. [0003] The traditional prefabricated fragments are all square after the e...

[0002] Currently as Figure 4 The structure of the prefabricated fragment warhead shown is that a steel structure casing is provided on the periphery of the grain, and prefabricated fragments are arranged on the inside or outside of the steel structure casing; in this way, after the explosion of the grain, part of the force is used to push away the steel structure casing, and the other part acts on the prefabricated fragments. The stress on the prefabricated fragment is relatively reduced, which affects its destructive force when it reaches the target

At the same time, when the explosive column explodes, the steel shell fragments will affect the flight speed and flight trajectory of the prefabricated fragments, seriously affecting the effectiveness of the prefabricated fragments

[0003] The traditional prefabricated fragments are all square after the explosion, and the air resistance they encounter during the flight is large, which reduces the penetration of the target
