The invention provides an explosive round that produces fragments propelled by jetting effect, the round consisting in a firing head, an explosive charge, a fragment generating wall in direct contact with the explosive, which wall has a set of indentations extending towards the inside of the round and into the explosive, so that each indentation constitutes a shaped charge, wherein the indentations of the fragment-generating portion are in the form of caps extending inside the explosive, each cap presenting a surrounding base having a diameter comprised between 2.5 mm and 5.5 mm and a wall thickness comprised between 0.5 mm and 0.8 mm, so that each cap generates a corresponding fragment propelled by jetting effect, fragment which has no effectiveness beyond 35 m from the point of explosion.

Explosive round with controlled explosive-formed fragments

A device for dispersing birds in airport areas, including a self-propelled projectile with a delayed firing element (,) and a sound-effect charge (,) designed to scare birds away and housed in said projectile.

Device for controlling bird strike hazards

The projectile, in particular a bullet, comprises a body (1) comprising a receiving cavity (6) containing a product (8) which is active on the organism of a live target, and means for releasing this product upon the impact of the projectile on the target. The body (1) of the projectile includes a propelling motor (5) and, along the length of the body, a portion (30) of smaller diameter followed by a shoulder (32) constituting a braking plane perpendicular to the direction of travel of the projectile. Application in bullets for disabling an opponent with no risk of fatal injury.

Projectile, in particular a non-lethal bullet

Delay igniter plug for pyrotechnic machine, in particular manual or mechanical launch grenade, comprising a body (4) fitted with a control mechanism comprising a trigger lever (1) and a percussion mechanism (28) interacting with a primary pyrotechnic module provided with a primer (3), a retardant composition (9), a primary explosive (13) which are capable of ensuring initiation of the charge of the associated machine which is arranged so that the primary explosive (13) cannot be initiated without going via the retardant composition, the primary pyrotechnic module (5) being axially displaceable in the said body toward the principal charge, means (2) for holding the primary pyrotechnic module (5) axially separated from the principal charge (19) and a screen (12a, 15) interposed between the principal charge and the terminal part of the primary pyrotechnic module containing the primary explosive (13), characterized in that the means (2) for holding the primary pyrotechnic module (5) axially separated from the principal charge (19) are exclusively mechanical means, actuated by the trigger lever (1) and in that the screen interposed between the principal charge and the terminal part of the primary pyrotechnic module (5), comprises a closure cap (15) of a cup (18) containing the principal charge (19) and a pellet (12a) carried by the end of the primary pyrotechnic module (5) containing the primary explosive (13) and engaged in the cap (15), the pellet (12a) and the cap (15) being shaped in order to be made integral with each other in the case of excitation of the primary explosive (13) in the storage position and to create a physical barrier to the shock wave or to the fragments.
