  • Patent number: 7603951
    Abstract: A projectile having a reactive material disposed therein is provided. The projectile includes a housing which defines a cavity, the cavity being open at one end of thereof. A reactive material is disposed within the cavity. A tip is coupled with the housing and substantially encloses the opening of the cavity. The housing, the reactive material and the tip are cooperatively positioned and configured so as to define a void space between a surface of the tip and a surface of the reactive material. Upon impact with a target, the tip of the projectile is designed to become displaced within the cavity until it contacts the reactive material and transfers kinetic energy thereto, thereby causing ignition of the reactive material. The void space may be defined to provide a desired amount of time between initial impact of the projectile with a target and the subsequent ignition of the reactive material.

  • Patent number: 7584922
    Abstract: A spin-stabilized correctible-trajectory artillery shell has a generator in the rotation-decoupled engagement region between a canard guidance unit and its munition body. The generator can be switched over to avoid load fluctuations between an adjusting motor and a substitute load. In order to avoid an additional heat source in the interior of the guidance unit the substitute load is in the form of an electrical resistance on, at or in canard surfaces behind the afflux flow edges. The canard surfaces are preferably formed on anti-spin canards which are not adjustably mounted.

  • Publication number: 20090200376
    Abstract: A method for shooting a projectile weapon involves determining the inclination of a line of sight from a vantage point to a target and a line-of-sight range to the target, then predicting a trajectory parameter at the line-of-sight range, for a preselected projectile. Using the trajectory parameter, an equivalent horizontal range may then be determined, wherein the equivalent horizontal range is the range at which the trajectory parameter would be expected to occur if the projectile were shot from the vantage point toward a theoretical target located in a horizontal plane intersecting the vantage point. The equivalent horizontal range may be utilized to compensate for ballistic drop when shooting the projectile weapon. The method may be embodied in a handheld laser rangefinder including a memory for storing ballistic data. Systems for automatic hold over adjustment in a weapon aiming device are also disclosed.

  • Publication number: 20090193995
    Abstract: An inertial delay mechanism for use in an explosive projectile is provided. The delay mechanism consists of an inertial delay fuse that is precise, doesn't require sensitive primary explosives and doesn't utilize electronic circuitry. The inertial delay fuse includes a free sliding charge element that strikes an anvil located opposite to the sliding charge element. A delay gap is provided between the sliding charge element and the anvil. Upon impact, the sliding charge element slides forward and impacts the anvil, thereby inducing a shock wave in an initiator charge that subsequently results in detonation of main charges. The design is mechanically simple and robust enough to withstand severe g-loading forces that occur during firing and penetration of a projectile.

    Abstract: A rifled slug is provided with a metal head (1) and a plastic rear part (2), which is made as a single piece from a pin-shaped front part (5), with a rod-shaped middle part (6) joined to the rear of the front part, and with a plunger-shaped rear part (7). The front part (5) is inserted from the rear into a pocket hole of the metal head (1) and is joined thereto in a captive manner. This improves a rifled slug of the aforementioned type by increasing the precision, i.e. reducing the dispersion in the target. To this end, the front part (5) is provided in the form of a hollow body and is joined to the middle part (6) via a predetermined breaking point (14), whereby when shooting, the middle part (6) slides into the cavity of the front part (5) until the upper surface (19) of the rear part (7) strikes the lower surface (20) of the front part (5).

  • Patent number: 7222573
    Abstract: A projectile for an air arm is integrally formed from a single piece of dense malleable material formed as a body of revolution about a longitudinal axis having a head portion dimensioned for free sliding in the bore of an air arm and a skirt-like portion of frusto-conical form. The rearward end of the skirt portion is dimensioned to be in slight interference fit with the bore and the forward end is joined with the head portion to define a reduced diameter waist. The frustum is shell-walled, having a central recess opening to the rear and extending forwardly into the head portion. The head portion has a parabolically shaped outer surface which transitions smoothly into a hyperbolically shaped outer skirt surface for aerodynamic efficiency. Vanes are formed on the head portion to enhance in-flight spiraling rotation.

  • Patent number: 7219607
    Abstract: Projectiles for firearms, specifically bullets, are discussed that include a rear thin-walled counter bore. The counter bore is designed to be a first size and shape when the bullet is loaded into the firearm and expand upon discharge of the firearm so as to force the walls of the counter bore into barrel rifling. The expansion may occur through the direct interaction of propellant gases with the counter bore walls, or at least partially indirectly though the inclusion of an expansion plug that is placed at least partially within the counter bore in a manner that the expansion plug can be driven further into the counter bore by the firing action of the firearm.

  • Patent number: 7178462
    Abstract: A projectile includes members that deploy upon impact with a target. The projectile includes a nose piece with a portion that shears off upon impact with the target, causing the nose piece to be pushed inside the projectile. As the nose piece is pushed inside the projectile, the nose piece pushes on members that deploy outwardly and lock into place, thereby greatly increasing the damage done to the target. The projectile is easily assembled by placing the two members through an axial cylindrical hole into slots, then placing the nose piece into the axial cylindrical hole. The deployable members are held within the body of the projectile in flight, and only deploy when the projectile strikes a target, greatly increasing the damage to the target.

  • Patent number: 7174835
    Abstract: A covert tracer round has an infrared emitter of radiation mounted to its front, side or back. The radiation (which may be coherent or incoherent) is detected by a sensor that displays an image of the target and the beam. The sensor receives the beam directly if the emitter is on the back of the round and by reflection off the target or nearby objects if the emitter faces forward. The round may include a fixed or moveable collimating lens. The emitter may radiate radially from the round to signal troops or devices located along its path. The round may include sensors that gather significant information about chemicals or biological agents, about magnetic or gravitational anomalies or any other remotely detectable property and transmit that information to the sensor by modulating the emitted radiation.
