Abstract: A hand-throwable grenade shaped in a triangular form to provide more sturdiness and accuracy when thrown. The unique shape of this grenade allows for a more comfortable hold and prevents the grenade from rolling away or back from desired target. Not only was it designed with versatility, but the grenade allows the user to infuse it with different materials. These materials include C4, gunpowder, tear gas, and any kind of chemical. This grenade was invented with the Armed Forces and a special application in mind.

Abstract: A rotational variable pyrotechnic delay selector for munitions which permits the selection of various ignition delays. Advantageously, the variable delay selector is configurable for a variety of field conditions and targets and is adaptable to a number of munitions systems and pyrotechnic ignition mixtures and delays.

Abstract: A fuze for a projectile has a firing assembly for firing a main charge of the projectile and a delay detonator for firing the firing assembly after a delay time which is defined by a burning distance of a delay charge. The delay detonator has a housing with a fuze half in which it is fired and a detonator half which contains a detonator charge for firing the firing assembly. In order to prevent the projectile from misfiring as a result of premature detonation of the delay detonator, the housing has a relief opening in the fuze half, with an opening cross section that can be passed through freely in the firing state of the delay detonator.

Abstract: A projectile which includes a pyrotechnic delay element placed between the fuze and the high explosive.

Abstract: A priming system for the explosive charge of a sub-munition carried on board a carrier comprises a main firing pin, a primer tube operative to move from a safety position to an armed position, at least two devices to lock the primer tube in the safety position before the sub-munition is ejected, and a self-destruct mechanism operative to destroy the sub-munition after a predetermined delay. A first one of the locking devices is formed of a cam operative to move from a cam safety position, in which it forms a limit stop preventing the primer tube from passing freely into an armed position, to a retracted position in which it allows free passage of the primer tube. The cam carries an auxiliary firing pin to ignite a delay cord of the self-destruct mechanism. A second one of the locking devices engage the primer tube by the percussion tip of the firing pin to hold the primer tube in a safety position.

Abstract: A shock sensing dual mode warhead is provided for use against both soft and ard targets and is capable of sensing which type of target has been struck. The warhead comprises a casing made of a ductile material containing an explosive charge and a fuze assembly. The ductile warhead casing will mushroom upon striking a hard target while still confining the explosive. Proper ductility and confinement are necessary for fuze shock sensing. The fuze assembly contains a pair of parallel firing trains, one initiated only by dynamic pressure caused high impact deceleration and one initiated by low impact deceleration. The firing train actuated by high impact deceleration senses dynamic pressure transmitted, during deformation of the warhead, through the explosive filler which is employed as a fuzing signature. The firing train actuated by low impact deceleration contains a pyrotechnic delay to allow penetration of soft targets.

Abstract: An impact fuse for a projectile comprises a firing needle and a main detonator carried by a rotor. The rotor is rotatable about an axis, upon launching of the projectile, and is rotated by centrifugal force from a safety position to a firing position in which the firing needle is aligned with the main detonator. Upon target impact, the rotor is displaced axially to cause the firing needle to detonate the main detonator. Acceleration forces occurring upon launching cause a piercing pin to activate a delay detonator. After a pre-selected time delay, the activated delay detonator emits a gas which displaces the rotor axially and produces detonation of the main detonator, in the absence of target impact.

Abstract: An ignition and safety device for a grenade projectile provided with a shaped charge insert and having a bottom-side impact fuse that has a spin-dependent safety element and acceleration-dependent safety element (14, 17), and a self-destruct device. The self-destruct device includes a pyrotechnical delay segment (29) that is axially displaceable into engagement with a firing pin (30) by means of the launch acceleration and acts on a booster charge (8), which is disposed extremely off-center of the projectile axis for the projectile effective charge. Consequently, no shaped charge jet is formed during self-destruction for the projectile.

Abstract: A multiconnector whereby a primary length of low energy fuse can be connected to a selected number of secondary lengths of low energy fuse has an inlet port into which an end of the primary length can be inserted and a number of outlet ports into which ends of secondary lengths of fuse can be inserted. The outlet ports and the inlet port communicate via internal passages. The outlet port may be closed by removable plugs or rupturable membranes so that those outlet ports that are not used do not establish a communication path between the inlet port and the atmosphere or the multiconnector may have two parts that are relatively displaceable so that the number of outlet ports that communicate with the inlet port can be set by relative displacement of the two parts.

The slider is slidable in a lane normal to the axis of the striker pin and carries additional to the detonator a pyrotechnic device comprising an igniter charge, a booster charge removed therefrom and located in close proximity to the detonator, a delay charge between the two and swingable striker means which become unlocked in the armed state and are adapted to strike the igniter charge in consequence of centrifugal forces that develop in the course of flight. The delay of the pyrotechnic device is designed to outlast the flight time of the grenade. Whenever the striker does not strike the detonator when the grenade hits the target, the detonator is initiated by the booster charge of the pyrotechnic device.

A detonator is held in the second safety slide such that in one position of the second safety slide it is out of axial alignment with the point and in another position thereof it is in axial alignment with the point for allowing contact between the point and the detonator.

Abstract: A projectile is provided for penetration into targets of both slight and great resistance to penetration. The projectile is also operative for exploding the payload of the projectile after penetration. The projectile includes a forward barrier of high strength material and a fuse adapted to be detonated on impact with targets. This fuse operates with high sensitivity on impact with targets of slight resistance to penetration and by delayed action which permits explosion of the payload of the projectile after penetration. A delayed action charge included in the fuse is placed behind the barrier and is allocated a protected position where shock waves which occur in the forward material portions of the projectile are prevented from triggering or actuating the delayed action charge. The delayed action charge is exposed to a unit placed between the barrier and the delayed action charge, the unit, when the fuse is detonated, effectuating a reliable ignition of the delayed action charge.
