Abstract: A projectile includes an explosive charge, a corresponding initiating device, a penetrator that only deforms upon impact with a target having a predetermined mechanical resistance, an internal impact contactor arranged between the penetrator and the charge, and a device to ensure initiation of the charge following crushing of the internal impact contactor and after the explosive charge has begun to be deformed following impact on the target. The projectile is particularly effective against hard targets such as stone, brick or cement structures.

Abstract: A device for reducing drag of a round of ammunition or projectile (1) comprises a gas-producing compound (3) such as a propergol, the combustion of which generates gases at a pressure of at least sufficient value to fill the low-pressure region which is formed at the rear end of a projectile and causes drag. The device comprises a gas-tight casing (2) containing the explosive compound (3) and an igniter (6) for initiating combustion of the compound. The casing comprises fasteners which cooperate with complementary fasteners (11) arranged at the rear end of the round of ammunition so as to permit gas-tight fitting of the casing at the rear end of the projectile, at any moment and in particular at the firing location, in order to reduce drag and to increase the range of the projectile.

Abstract: A rifle grenade comprises, at one end, a tube designed to be fitted to the barrel of a gun and, at the other end, a fuse and a head enclosing an explosive charge, the said tube comprising, upstream of the fuse, a bullet-trap and a booster-charge of propellant powder protected from external influences by a sealed wall.The said sealed wall is integral with a tubular element of the said tube and comprises an axial cavity defining a reduction in the thickness of the wall sufficient to ensure that the bullet shot by the gun shall pierce the wall without tearing it.The purpose is to increase the operational safety of rifle grenade.

Abstract: A bullet trap device for launching, by firing a live bullet, ammunition such as a grenade having a trailing tube to impart thereto a flat trajectory of fire, includes a body to receive the impact of the live bullet, a supporting piece for positioning the body within the trailing tube of the grenade, and a shock absorber part positioned axially between the body and a portion of the supporting piece. The body and the shock absorber parts are formed as an integral, one-piece, solid-forged assembly. A centering ring, separate from the supporting piece, is positioned radially between the shock absorber part and the supporting piece, thereby maintaining the body and the shock absorber part centrally of the axis of the trailing tube of the grenade after firing.
