Abstract: The present invention relates to a non-lethal projectile. The projectile (1) comprises a longitudinal body (5) having internally a longitudinal striker (55) suitable for perforating a container (47) of fluid under pressure in controlled manner, in particular by impact of the projectile (1) on a target. The striker (55) has an internal passage (59) opening to the outside of the body (5) via channels (60) made through a rigid wall (35) secured to the body (5) such that the outlet offered to the fluid under pressure remains disengaged even if the impact is accompanied by the deformation of the container (47). The fluid contained in the container (47) can thus escape and spread over the target even in such a case.

It is characterized in that the container (12) is substantially cylindrical, the dispersive explosive charge (16) being situated at the level of the container axis and in that the marker composition comprises at least one pigment in the form a solid, coloring powder dispersed in water, the powder being combined with a water-soluble binder and with a rheological component which is also water-soluble and which is intended to agglomerate the pigments and to increase the composition's viscosity, the composition further including an antifreeze agent.

Abstract: An aerodynamic device, such as a projectile includes an elongated forebody, and an aft section secured to the forebody. The aft section acts as a d control device, and includes a connecting member that extends integrally in a conically shaped flared section, for generating a lift force to help stabilize the projectile during forward flight. The aft section further includes a flange that extends from the flared section, and that provides velocity decay and optimal drag, in order to limit the projectile flight and descent within a predetermined safety or emergency range. The flared section is defined between an innermost edge positioned adjacent to the connecting member, and an outermost edge positioned adjacent to the flange.

The projectile has two or more shell layers made of explosive foil, each alternating with another shell layer made of supportive foil material, between a radially outer shell layer made of supportive foil material and a radially inner protective shell. The different layers made of explosive foil can be ignited sequentially when viewed radially from the outside to the inside.

Abstract: A pyrotechnic device includes a launcher for launching and igniting a plurality of pyrotechnic stars for creating an aerial fireworks display. The launcher comprises a launching tube having an igniter that ignites the pyrotechnic stars as they are being expelled from the launching tube under the force of pressurized air. The igniter may comprise a section of the launching tube having a locally reduced diameter so that the pyrotechnic star frictionally engages it during launch, causing a striker composition on the interior of the launching tube to ignite a prime composition on the exterior surface of the pyrotechnic star. Alternatively, the igniter may comprise a flame within the launching tube to ignite the prime composition on the star. Various feeding mechanisms are provided to rapidly feed a large number of pyrotechnic stars for launching from the launching tube. The launcher utilizes pressurized air to launch the pyrotechnic stars and, thus, minimizes adverse environmental impact.

There is provided a safety facility, which includes a breech block (7, 9) which is intended to be inserted into the adapter through the agency of a guide means (4, 5) which extends transversely to the longitudinal axis of the cylindrical breech (2) and when fully inserted forms the bottom of the breech.

Abstract: An exercise mine has a ballast portion, a generally barrel-shaped body constituted by a single piece molded about the ballast portion and a plurality of U-shaped metal fitting members having terminal portions that form resilient tabs which project outside the periphery of the body. The fitting members are secured together in groups to permit, along with the single molded body, the mine to be readily formed from just a few parts while ensuring the mechanical strength and durability of the mine.

Abstract: There is proposed an ejector device (6) for grenade projector or mortar projectiles (1), which permits simulation of mortar firing even in halls or very limited areas. It is known that blank cartridges (17) for rifles, pistols or bolt firing devices have only a slight degree of scatter in terms of gas pressure. Therefore the ejection speed of a piston (13) which is inserted into the ejector device (6) and which is driven by the powder propellent gases of the blank cartridge (17) is always the same. In that way it is always possible to achieve the same firing ranges of only a few meters.

Abstract: A lightweight training bomblet provided with a housing made of cardboard or plastic. Such training bomblet should be easily assembled and be able to withstand the high acceleration forces generated during transport into a target area. To prevent undue deformations of the bomblet housings made, for example, of cardboard, during air transport and the resulting premature ignition during ejection from a carrier projectile, both cardboard or plastic housing covers are connected with one another by means of a pre-tensioned connecting arrangement and their abutment faces are pressed against the end faces of a tubular housing shell, with the abutment faces of the housing covers possibly additionally containing a holding and sealing arrangement which is pressed into or against the end faces of the housing shell.

Leaf springs (72) formed in the housing wall hold the firing pin in a safety position until released by movement of a slider (82) caused by aerodynamic drag forces acting on deployable fins (96) or a parachute (92).

Abstract: A practice bomb designed to train air crews for use of laser-guided bombs. The practice bomb has an approximately similar ballistic coefficient to that of a laser-guided bomb. A laser seeker is fixed to the body of the practice bomb within its nose section. The laser seeker has means to provide an internal signal upon target acquisition. A smoke cartridge is secured in the practice bomb to release a smoke producing chemical to the atmosphere when activated, and appropriate means are associated with the laser seeker and smoke cartridge to activate the smoke cartridge upon receipt of the internal signal from the laser seeker. Such device provides a low-cost trainer which can be used to develop some of the skills required from air crews for delivery of laser-guided bombs.
