Liner release mechanism for anti-armor munitions

摘要

An Insensitive Munitions safety device mitigates the occurrence of a violent response of an anti-armor munition subjected to elevated temperatures. The anti-armor munition includes a projectile body having fore and aft ends, an explosive charge disposed in the projectile body, and a projectile-forming or jet-forming liner disposed in the projectile body. The liner includes an aft surface contiguous with the explosive charge and a fore surface that defines a void. A liner restraint abuts a fore end of the liner and restrains movement of the liner. A portion of the liner restraint comprises a material having a heat deflection temperature less than the critical temperature of the explosive charge in the munition.

主权项

1. An anti-armor munition, comprising:
a projectile body having fore and aft ends; an explosive charge disposed in the projectile body; one of a jet-forming liner disposed in the projectile body, the liner including an aft surface contiguous with the explosive charge and a fore surface that defines a void; and a liner restraint that abuts a fore end of the liner and restrains movement of the liner wherein at least a portion of the liner restraint comprises a material having a heat deflection temperature less than a critical temperature of the explosive charge in the projectile body; wherein, said liner restraint includes a projectile nose having a cylindrical portion that extends interior to the fore end of the projectile body and that abuts and restrains the liner; and an adapter having first and second portions, the first portion being disposed between the fore end of the projectile body and the cylindrical portion of the projectile nose, the second portion extending radially outwardly from the first portion and longitudinally away from the fore end of the projectile body to form a collar that abuts the fore end of the projectile body and abuts the cylindrical portion of the projectile nose.
