The present invention relates to a firearm projectile capable of releasing a secondary payload mid-flight through a pyrotechnic timing mechanism. Once the firearm is fired, the powder in the casing pushes out the projectile as a typical round. In addition, the powder ignites the delay column. The formulation and amount of delay pyrotechnics determines the delay time. When the delay column is burned, the final portion ignites an expelling charge. The expelling charge builds pressure in the projectile casing and separates the base plug from the main projectile housing. The expelling assembly pushes out the secondary payload out the rear of the projectile. Although the payload exits the rear of the projectile at minimum velocity, the net velocity of the payload is still in the forward direction.

A box by pin perforating gun system using swaged down gun bodies, a removable cartridge to hold a detonator and switch, and an insulated charge holder as an electrical feed-through.

The present invention relates to a cluster bomblet having an improved bomblet body, the cluster bomblet comprising: a cylindrical bomblet body (10) packed with high explosives; a fuse assembly (20) having a striker screw (21) for exploding the high explosives and coupled to the top side of the bomblet body; and a conical penetrator (15) provided inside the rear end portion of the bomblet body. The bomblet of the present invention has: a connecting tube (33) provided therein to seal the top side of the bomblet body (10) and to connect an initiating tube of the fuse assembly (20) and the high explosives (11); and an upper cover (30) into which a stud assembled to the fuse assembly is inserted, wherein the upper cover includes: an assembly surface portion (31) having a connecting-tube mounting hole (31a) and a stud insertion hole (31b) formed therein, the stud (22) being inserted into the stud insertion hole (31b); and a side wall portion (32) extending upward from the edge of the assembly surface portion (31) in order to prevent the separation of the mounted fuse assembly (20).

An inertial igniter for igniting a thermal battery, including: a base having a first projection; a striker mass rotatably connected to the base having a second projection, when the striker mass is rotated towards the base, the first projection impacts the second projection; a member having a first portion engaging with a second portion of the striker mass to restrict rotation of the striker mass unless a predetermined acceleration is experienced; a mass movable from a first position where an acceleration is less than the predetermined acceleration and a second position where the acceleration is greater than the predetermined acceleration to permit the first and second portions to come out of engagement; a spring for biasing the mass in the first position; and a rotation prevention member for permitting impact of the first and second projections when the predetermined acceleration is experienced and the mass moves to the second position.

The invention relates to an igniter device for igniting energetic materials, more specifically to the area of the initiation of munitions, and methods of forming said ignition devices. There is provided an igniter device, for use in an explosive train, comprising a first synthetic polymer layer, a second synthetic polymer layer, wherein said first layer and second layer envelope a portion of an energetic material, wherein said synthetic polymer is capable of being sealed.

An inertial igniter for igniting a thermal battery upon a predetermined acceleration event. The inertial igniter including: a base having a first projection; a striker mass rotatably connected to the base through a rotatable connection, the base having a second projection aligned with the first projection such that when the striker mass is rotated towards the base, the first projection impacts the second projection; a rotation prevention mechanism for preventing impact of the first and second projections unless the predetermined acceleration event is experienced; and a spring for biasing the striker mass in a biasing direction away from the base, the spring being disposed between a portion of the striker mass and a portion of the rotation prevention mechanism.

An artillery shell is fired out of a gun towards a fire. A trigger releases a fire-retarding material from the artillery shell to retard the fire.

An electromagnetic mobile active system for fitting in a missile with a detonation-operated magnetic field compressor. The magnetic field compressor has at least one stator coil and at least one armature casing, which is at least partially surrounded by the stator coil and kept at a radial distance. The magnetic field compressor has at least one explosive charge embedded in the armature casing. The magnetic field compressor has at least one power source. For activating the detonation of the explosive charge, a trigger system is provided. The trigger system can be controlled by a pulse of current from the power source, depending on a signal supplied by the missile. A great amount of electrical energy can be generated in the stator coil by the detonation. For the directional radiation of the electrical energy generated by the detonation of the explosive charge, the active system has at least one directional antenna.
