ADJUSTABLE STAND FOR HOLDING A LIQUID EXPLOSIVE
20170299348 · 2017-10-19 ·

A low-cost, reliable and easy to use kit for neutralizing surface exposed landmine and unexploded ordnance for humanitarian demining is based on a liquid fuel and a solid/soluble fuel. Both fuels are premeasured in separate, sealed containers. The addition of a small quantity of solid/soluble fuel into the liquid creates an explosive. The resulting mixture is capable of detonating with a standard No. 8 blasting cap. The solid/soluble fuel can be in the form of a powder, tablet, or its saturated solution in water. The solid/soluble fuel is hexamethylenetetramine. The liquid fuel, nitromethane, is provided in premeasured quantities. User is provided instructions for choosing the appropriate quantity of liquid fuel, the corresponding solid/soluble fuel required, the method of mixing, placement and detonation of the kits. Also disclosed is a simple wooden stand to hold the bottle of explosive in place. A special fuel, liquid 2-ethylhexylnitrate, is provided to desensitize the mixed and sensitized explosive.

ARTILLERY PROJECTILE WITH A PILOTED PHASE
20170299355 · 2017-10-19 · ·

The invention relates to an artillery projectile (1) which is intended to have a trajectory comprising a ballistic phase and a piloted phase. This projectile (1) has at least one means ensuring its aerodynamic stabilization on part or all of its trajectory and a means (9) intended to ensure a piloting during the piloted phase. This projectile is characterized in that the aerodynamic stabilization means comprises a wing system having at least two wings (16) which are able to positioned with respect to the axis (26) of the projectile, at least during the piloted phase, with their sweepback angles being negative, that is, with the free ends (16b) of the wings (16) being oriented towards the front of the projectile (1).

MULTI-WARHEAD MUNITION WITH CONFIGURABLE SEGMENTED WARHEAD
20170299358 · 2017-10-19 ·

A multi-warhead munition includes a first cylindrical warhead having a cavity filled with high explosive, and a second cylindrical warhead offset axially from the first cylindrical warhead. The second cylindrical warhead is a transformable, segmented warhead including a plurality of segments each having an outer segment face bounding a cavity of the segment filled with high explosive. The segments are elongated and mounted at one end for rotation away from an axis of the munition to an open position in which the segment faces are pointed in a forward direction for detonation. Rotation may generally be somewhere in a broad range from about 105 degrees to about 170 degrees, obtaining different effects in different sub-ranges. The munition includes first and second detonators for the first and second cylindrical warheads respectively, the second detonator simultaneously detonating the segments of the second cylindrical warhead.

Increased lethality warhead for high acceleration environments

A warhead device of an ordnance including a body of a high strength material, where the body includes a plurality of depressions; an explosive material, where the explosive material fills the body; and a plurality of reactive materials, where each reactive material fills a corresponding depression of the plurality of depressions on the body. The high strength material is configured to endure an internal stress, a first stress caused by the plurality of reactive materials, and a second stress caused by another component of the ordnance. The internal stress, the first stress, and the second stress are in response to acceleration of the ordnance.

Voltage induced porosity in insensitive munition

A method of selectively increasing the sensitivity of an insensitive munition by inducing porosity or Joule heating in munitions assembly comprising a power source, an explosive apparatus and a fuze apparatus wherein the explosive apparatus contains a sensitized main explosive composition comprising a secondary explosive and a sensitizing agent. As a result, the otherwise insensitive munition is rendered sensitive to a propagating wave shock by approximately 10 to 25%. To this end, a voltage is applied across the main conductive explosive composition within the insensitive munition. Voltages above certain thresholds cause the decomposition of the explosive material or conductive binder, which leads to an increase in porosity, and therefore the shock sensitivity.

Fragmentation munition with limited explosive force

A fragmentation munition has a fragmentation canister containing preformed fragments, and an explosive cartridge that fits into a central hole in the fragmentation canister. The explosive cartridge includes an outer shell, and an explosive within the outer shell. The munition may be configured to precisely deliver fragments to a relatively small area, such as an area that is a few meters in radius. Toward that end the explosive may be configured primarily to rupture the housing and secondarily to spread fragments over a limited area. The main kinetic energy of the fragments is from the acceleration they gain as part of the munition falls from a launcher, such as a carrier aircraft. The dispersed fragments may have a similar downward velocity after controlled dispersal by the explosive, allowing them considerable kinetic energy (considerable penetrating power), but with a precisely controlled dispersal area.

Clay-pigeon-like projectile for crowd control
09726447 · 2017-08-08 · ·

A crowd control projectile includes a payload carrier, an incapacitating agent inside the payload carrier, and an activating mechanism for activating the incapacitating agent. The activating mechanism includes a sensor and a timer. The timer delays the activation until a predetermined delay after the sensor senses that the projectile has been launched. Alternatively, the activating mechanism includes a receiver for receiving an activation signal after the projectile has been launched. Preferably, the projectile has the shape of a clay pigeon. A launcher of such a projectile includes a communication mechanism for transmitting a timing signal or an activation signal to the projectile and an arm for launching the projectile by direct contact. To control a crowd, the projectile is launched over the crowd by direct contact with a solid arm and the activating mechanism is used to activate the incapacitating agent when the projectile is above the crowd.

Fire-retarding artillery shell

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.
