  • Patent number: 8558151
    Abstract: A method for correcting a trajectory of a projectile is provided, in that a laser beam is guide or rotated around a center of the instantaneous target course of a projectile in such a way that the projectile itself detects a divergence thereof and subsequently carries our a selfcorrection. A first laser beam is emitted over a certain region around the target course of the projectile that can at about the same time initiate a start of a timing process. A further rotating laser beam having a fixed rotational frequency ? can be simultaneously positioned around the region. Via the second laser beam, the projectile recognizes a divergence thereof from the target course and initiates a correction based on the determined divergence, whereby a magnitude thereof is then used to effect the timed initiation of the correction. Thus, delays in the release are implemented in the projectile.

  • Patent number: 8223061
    Abstract: The invention proposes to provide distraction spoofing even on modern infrared, radar and dual-mode guided missiles (4) by production of a decoy chain (20). The chain (20) is formed by a plurality of apparent targets which are switched successively, for example by firing of individual chaff submunitions (2.1-2.5). The deployment takes place before or during the search phase of the missile and can in this case, for example, be carried out using the reverse walk-off principle or at the same time simultaneously or successively and in the form of a pattern. This ensures that the decoys (2.1-2.5) act initially in the greatest selected range zone away from the target (3). The spoofing chain (20) created in this way results in the missile (4) having to carry out a series of time-consuming analysis processes on its way to the target (3).

  • Patent number: 8198572
    Abstract: A projectile has a pair of different parts with respective orientation sensors for detecting orientation, such as the roll position of the parts. The orientation sensors may be any of a variety of sensors, such as magnetometers, light sensors, infrared (IR) sensors, or ultraviolet (UV) sensors. Orientation events of the orientation sensors, such as maxima or minima of sensor output, are determined. The orientation events of the two sensors are compared to produce an alignment correction factor for correcting for misalignment of the parts relative to one another, that is to correct for differences in alignment between the sensors of the two parts. This allows (for example) instructions produced at one of the parts to be usable at the other of the parts.

  • Patent number: 8176850
    Abstract: A multi-piece projectile for a small arms cartridge includes a metal cup that has a bore, a plastic sheath having a through hole and a high-density core. The cup is a cylindrical metal structure having a bore. The sheath is a cylindrical end and a conical end and a through hole. The core is a cylindrical structure having conical end and a blunt end. The projectile is assembled by placing the core in the through hole of the sheath and then pressing the sheath into the bore of the cup. The assembled projectile is attached to the cartridge by crimping the cup to the orifice in the end of the cartridge casing after it is filled with the propellant. When the projectile is fired all of the components remain coupled together but break apart upon impact with a target. Because the core has a higher mass than the other components the components separate very easily, the majority of the kinetic energy remains in the core.

  • Patent number: 8171853
    Abstract: A projectile for delivering an incapacitating agent through a barrier includes a canister containing the agent and having a closure. The canister is retained in a holder to which is fixed a sleeve formed of a plurality of axial fingers configured to spread radially outward upon impact with the barrier. A ballistic body, configured to penetrate the barrier and having a dispersion port, is connected to the holder forward of the canister so as to be axially movable from a forward position to a rearward position upon impact with the barrier, the ballistic body including a closure-breaching member located so as to breach the closure as the ballistic body moves rearward, thereby placing the canister in fluid communication with the dispersion port. The fingers spread radially against the surface of the barrier opposite the dispersion port so as to lodge the projectile in the barrier.

  • Patent number: 8171850
    Abstract: A weapon conditionally activates a cartridge. The cartridge has a projectile and a first mechanical feature. The weapon includes an activator and a station. The activator includes a second mechanical feature. The station positions the cartridge so that the first feature opposes the second feature. On condition that the first feature does not mechanically interfere with the second feature, the activator activates the cartridge to launch the projectile from the cartridge. On condition that the first feature mechanically interferes with the second feature resulting in an excess head space, the activator is inhibited by the excess head space from activating the cartridge.

  • Patent number: 8146499
    Abstract: This invention relates to a method and a system for activating a munition charge. It also relates to a munition fitted with a high precision activation device. Finally, it relates to a system for neutralization of a target. A laser beam (21) is used for illuminating an object (3) located close to the target (X), firing of the charge (23) of the munition being activated using detection by the munition of the laser spot (24) reflected by the object (3). Firing is activated at a time t1 after the time t0 at which the laser spot (24) is detected. The invention is applicable particularly to hit hidden targets for which a direct impact with these targets is not necessary.

  • Patent number: 8141494
    Abstract: The decomposition of a projectile in a target body, particularly a hunting projectile in wild animals after penetration therein, determines the energy output of the projectile and thereby the effect of the shot. For projectiles with double cores, the properties of the ingredients used in the cores decisively affect the decomposition and particularly the deformation behavior of the cores. According to the invention, a partial decomposition projectile comprising two cores is provided with one solid core (3) made of a material suited to said projectile and the second core (4) is made of a powder (5) consisting of metal or ceramic ingredients, said powder being pressed to become free of shrink holes, in order to improve decomposition behavior control.

  • Patent number: 8119956
    Abstract: A multi-stage hyper-velocity kinetic energy missile (HVKEM) uses a ‘missile in a missile’ architecture in which the HVKEM includes a 1st stage flight missile and a 2nd stage kill missile that includes a KE-rod penetrator. The flight missile cruises at a relatively low velocity (less than Mach 1.5, typically less than Mach 1) to conserve propellant (weight) and to allow for effective guidance and maneuvering until the missile is in close proximity to the target. When the missile is within the lethal range of the KE-rod penetrator, the kill missile separates and boosts to a much higher velocity (greater than Mach 3, typically greater than Mach 5) and flies unguided to impact the target in less than a second. Waiting to boost the KE-rod until “the last second” reduces the total propellant (weight) needed to deliver the KE-rod on target and simplifies the guidance.

  • Patent number: 8119958
    Abstract: A matrix of explosive cells can include plural explosive cells formed in an array in a common substrate. Each cell can be formed as a recess filled with explosive material. An ignition device has an addressable ignition source for each cell. This matrix can be used in combination with a projectile guidance system. The projectile guidance system includes an antenna, a transceiver and a control processor. A method of guiding a projectile can include firing a projectile at a target, tracking the projectile and the target, determining a desired change in a flight path of the projectile, transmitting guidance commands to effect the desired change in the projectile's flight path to the projectile, receiving the guidance commands onboard the projectile and selectively igniting an explosive cell in a matrix of addressable explosive cells contained in a common substrate using the guidance commands.

  • Publication number: 20120017794
    Abstract: Some embodiments pertain to an example projectile that includes an enclosure and an umbilical interface that is exposed on the enclosure. The projectile further includes an umbilical interface cover attached to the enclosure such that the umbilical interface cover protects the umbilical interface. The umbilical interface cover includes a casing and a sensing system inside the casing. The sensing system monitors conditions that the projectile is exposed to until the umbilical interface cover is removed to expose the umbilical interface. The sensing system allows the umbilical interface cover to record data related to the conditions that the projectile is exposed to until the umbilical interface on the projectile is mated to a launcher's umbilical interface. The recorded data may provide valuable information in diagnosing why there was a projectile mission failure.
