Abstract: An anchoring system for anchoring a projectile launcher to the ground. The launcher includes a tubular body accommodating at least a projectile to be fired and a propellant charge. The system further includes least one anchoring element that penetrates the ground when the projectile is fired. The anchoring element can be moved between a first position in which it is at a distance from the ground and held by a body of the launcher by means of a temporary attachment device, and a second position in which it penetrates the ground. A control system causes the anchoring spike to move automatically from its first to its second position and is constituted by the pressure of the gases resulting from ignition of propellant charge.

Abstract: The invention provides a lateral gas jet piloting device comprising at least one pair of diametrically opposite nozzles and a sliding bar comprising bistable pneumatic means ensuring reciprocal movement thereof so that the ends of said bar close alternately coupling ducts disposed between the nozzles and an external gas generator.

Abstract: A guided projectile comprising an energy source supplying a gas flow which feeds two pairs of exhaust nozzles, each pair of nozzles being disposed in the corresponding steering plane. Each of these nozzles is provided with a valve for regulating the relative flowrates of the throughflowing gases; this valve being formed essentially by a pivoting vane hinged about an axis; these vanes are interlocked in pairs and positioned by means of two independent mechanisms formed by a deformable parallelogram, the element 40 being the drive element. According to the invention, the directions of the thrust forces created by the nozzles converge at a point P situated on the axis of the projectile and this point P may merge with the center of gravity G of the projectile.

Abstract: The invention concerns a process and apparatus for transporting and dropping a plurality of charges contained in a single container. Within the shell of the container is arranged a plurality of modules, the bodies of which contain a charge, which may particularly be military; said modules are extracted one by one, upon command, through the rear of the shell. This extraction can take place only if a general mechanical control element has moved from a position called the "safety" position to a position called the "cocked" position, a movement which can take place only when the means for fastening the container has been released from the lug holding it to the carrier vehicle. The invention is applied particularly to modular bombs having fragmentable modules designed for neutralization of relatively widespread ground targets.

Abstract: A firing turret which can be oriented about its axis, permitting flat-trajectory or curved-trajectory firing of artillery projectiles. It includes a disc whose central portion includes an opening in the interior of which the cradle of the weapon can pivot; the disc is free to turn within a circular opening provided in the lateral wall of the turret. A turret of this kind may be used to equip an automotive or trailed vehicle.

Abstract: A steering arrangement for missile type projectiles. A source of steering propulsion which is accommodated in the vicinity of the center of gravity of the missile comprises two gas generators which are positioned symmetrically on either side of the center of gravity a system being provided to switch or divert the gases to the exterior of the missile in at least two directions which are transverse to the projectile and to its axis.The arrangement according to the invention considerably improves the reliability and effectiveness with which the projectile is steered.

Abstract: A projectile having an elongated body portion to the aft end of which is attachable a base constructed of thinner metal than the projectile body, there further being an isotropic charge positioned in the projectile which is subjected to pressure via the base when the charge is exploded in a gun barrel. Also taught is a method of assembling the charge into the projectile.
