Abstract: A shock wave initiator device for initiating a percussion primer includes a primary explosive, an attenuation body, and a deflagrating member. The primary explosive is of a type which upon ignition is capable of detonation for producing a shock wave. The attenuation body is a block or core of material which at its exterior engages a cup of a primer enclosing primer mix and at its interior has a cavity housing the primary explosive. The body is capable of transmitting the shock wave produced by the detonation to the primer cup. The deflagrating member is preferably a rapid burn cord with one end communicating with the primary explosive and an opposite end communicating with a source of input energy for igniting the cord to cause burning thereof which, in turn, ignites and detonates the primary explosive.

Abstract: An enabling device 24 for a gas generator 42 of a forced dispersion munitions dispenser 10 includes a housing 58 in which and formed a bore 60, an outlet lead 88 and a detonator opening 68 in which is positioned an electrically initiated detonator 70. A piston 62 is located in the bore 60 and has a disabled position and an enabled position. A safety groove 64 is formed in the outer surface of the piston 62, and a safety passage 72, a safety aperture 74, 75 and a transfer lead 86 are formed in the piston 62. A gas generator 42 containing a quantity of pyrotechnic material 84 is mounted on the housing 58. The gas generator 42 is provided with a safety outlet 46, 47 and an inlet lead 44.

Abstract: A firing train function indicator 10 for a self neutralizing recoverable land mine 16. An explosive bolt 20 is used to hold a helical spring 44 in a compressed state. The upper portion 30 of the bolt 20 is attached to one end of the spring 44 and the other end 32 of the explosive bolt 20 is attached to base 38 of indicator 10. A highly visible inverted cup-shaped flag 48 is also attached to the upper portion 30 of the explosive bolt 20. The detonator 18 of the explosive bolt 20 is fired when the mine 16 self neutralizes to separate the upper portion 30 of the bolt 20 from its lower portion 32. The spring 44 is then free to expand raising the flag 48 above the self neutralized mine 16. A flag 48 so deployed, identifies the location of a self neutralized mine 16 and is a reliable indicator to recovery personnel that the mine 16 is in fact safe to approach and recover.

Abstract: The method of preventing improper functioning of an armor piercing projectile having an axial hollow liner around which the explosive of the projectile is consolidated which comprises consolidating an axial pellet of explosive into the rearward portion of said liner.
