  • Patent number: 10690459
    Abstract: A fuze booster includes a first explosive charge having a cavity with an annular portion of the first explosive charge encircling a first axial portion of the cavity and a semi-annular portion partially encircling a second axial portion of the cavity. The annular portion abuts the semi-annular portion. An explosively-inert material abuts the semi-annular portion, abuts the annular portion, and partially encircles the second axial portion of the cavity. A second explosive charge abuts the explosively-inert material, abuts the semi-annular portion, and partially encircles the second axial portion of the cavity. The second axial portion of the cavity is thus completely encircled by a combination of the semi-annular portion, the explosively-inert material, and the second explosive charge.

  • Patent number: 6968785
    Abstract: The locking and stabilizing device for grenades utilizes a solid nylon ring and multiple nylon ribbons that are attached to the ring at regular intervals around its circumference. During storage, the ring surrounds and locks the slider of the grenade in its storage position. But upon deployment, under aerodynamic forces the ring moves away from the slider, releasing the slider. When the slider is thusly released, it slides out and brings the detonator in place to be impacted upon by the pin when the grenade hits the target, thus detonating the grenade. The multiple ribbons extending from the ring unfurl due to the aerodynamic forces and provide stability to the grenade flight.

  • Patent number: 6293202
    Abstract: A standoff delivery system is responsive to GPS coordinate signals and in-flight GPS signals to deploy a torpedo at a remote location that avoids the limitations and hazards attendant conventional deployment by full size aircraft. A gliding rigid winged unmanned aircraft carries the torpedo to a desired remote location. A GPS receiver on the aircraft enters GPS coordinate signals representative of the remote location and receives GPS signals representative of the location of the unmanned aircraft. A control signal generator produces control signals in response to both of the GPS signals and feeds control signals to servos that displace control surfaces to pilot the unmanned aircraft. The torpedo is released and descends via parachute in response to GPS signals that are representative of at least the proximity of the remote location. This system provides for clandestine deployment of a torpedo without exposing manned aircraft to danger.

  • Patent number: 5109774
    Abstract: Disclosed is a new type of penetrating projectile, the penetrating capacity of which is improved and more efficiently controlled, notably through a solution to the problems of obliquity. A projectile of this type has a front element forming the active part, fixedly joined to a tube. The tube has a closed end which contains a propellant charge for the propulsion of the element and an igniter for the charge, responding to the impact of the element on a target. In reaching the target, the projectile penetrates it slightly under the effect of the velocity and it is only at this instant, or slightly after it, that the penetration proper takes place. The penetration thus takes place without obliquity. This projectile can be used as an individual munition or sub-munition.

  • Patent number: 5016534
    Abstract: In a missile for setting down a load ejected from the missile after its launch, with at least one parachute that is attached to the load being packed in a container mounted in the missile, and with the cords of the load-carrying parachute being attached to an intermediate member coupled to the load, the intention is to reduce the size of the operational parts to be transported with the missile and improve the operation thereof during the setting down process. For this purpose it is envisaged that the container should be in the form of a two-part casing having an upper part which can be sprung open, and a plate-shaped lower part having a portion fixedly connected to the load and a support disk as the intermediate member attached to cords of the parachute. The support disk is capable of being folded out from the lower part portion while remaining connected thereto by a connecting element.

  • Patent number: 5003882
    Abstract: For suspending a sub-munition from a plate carried beneath a parachute, an arm is hinged with the plate and the body of the munition, and a structure has two positions for which the sub-munition is respectively vertical or inclined. The structure also includes a system of guiding the tilting between the two positions. The center of gravity of the sub-munition moves downwards on a vertical line during tilting of the sub-munition to an inclined position. The device forming the subject of the invention enables the swinging caused by tilting the sub-munition into an inclined position to be avoided, and it is simple and economical to manufacture.

  • Patent number: 4889030
    Abstract: A projectile has at two parts (3, 4) axially arranged one behind the other and mutually linked, of which at least one contains a deployable parachute (6, 6'). In order to achieve a design that ensures a smooth and reliable separation of the parts (3, 4), followed by the deployment of the parachute (6, 6'), both parts (3, 4) are mutually linked by radial bolts (19) that can be radially actuated by the gas pressure generated by at least one pyrotechnic load (15) and radially moved by the gas pressure, thus separating the two parts (3, 4). The pyrotechnic load (15) can be ignited by a fuse (9).

  • Patent number: 4878433
    Abstract: A device for neutralizing military objects by means of sub-munitions released by a mother rocket onto mobile targets on the ground. Each sub-munition (1) is provided with a military charge (2) and a wide range sensor (3) and descends while suspended from a parachute and turns uniformly about a vertical axis of symmetry (10), the angle formed by the firing axis (5) and the vertical being constant. Superimposed upon this rotational movement of the sub-munition, the periodic oscillatory movement of an orientable mirror (14) permits varying the direction of the optical axis (8') with respect to the firing axis during the detection phases of a target and the guiding of the sub-munition towards the detected target. Thus at each oscillation period of the orientable mirror the complete image of the circular area on the ground is obtained. In the last phase of firing, when aimed at the target, the optical axis is maintained in the direction of the firing axis.

  • Patent number: 4876963
    Abstract: The invention relates to bombs intended to be released at a very low altitude so as to damage high mechanical resistance surfaces and more particularly antirunway bombs equipped with a downward or acceleration propulsive unit. Each bomb comprises means for braking and orienting it during its initial fall, so as to position the bomb in a plane activating an upward propulsive unit. These means are formed of at least one parachute placed at the head of the bomb. With the activation position reached, the upward propulsive unit causes the bomb to rise and, during the final fall of said bomb, a downward propulsive unit, placed in front of the upward propulsive unit, accelerates the final fall of the bomb so as to accumulate high kinetic energy at the time of impact on the ground.
