  • Patent number: 10094644
    Abstract: To increase the range of a spin-stabilized projectile which moves in a surrounding medium, the surrounding medium from a stagnant-water region of the projectile is, by means of a part of the rotational energy of the projectile, conveyed under the inflowing boundary layer at the outer surface of the projectile, and thus the speed gradient of the boundary layer in the vicinity of the wall is reduced. For this purpose, the outer surface has at least one encircling groove (9) which is connected by radial transverse ducts (10) to at least one longitudinal duct (11) in the interior of the projectile, which in turn is connected to an opening in the rear of the projectile.

  • Patent number: 8993948
    Abstract: A spinning, rolling, or roll-stabilized vehicle, such as a projectile, includes a fuselage that rotates about its longitudinal axis (spins) during flight. A collar is positionable relative to the fuselage to steer the projectile, with the collar having ailerons to provide a roll force to position the collar. The collar also has elevators to provide lateral force to steer the projectile. The positioning of the collar may be accomplished by moderating the roll force of the ailerons to hold the position of the collar substantially constant with regard to a longitudinal axis of the projectile. The ailerons passively change angle of attack with changes in the dynamic pressure of the projectile. At low speeds the ailerons have a relatively large angle of attack, and at high speeds, the ailerons resiliently reduce their angles of attack, avoiding large rolling forces on the collar.

  • Publication number: 20150033973
    Abstract: The current invention is directed to a cost effective method of manufacturing bullets or projectiles for firearms which are identifiable after firing and undergoing damage. The mass production of low cost ammunition makes adoption of a requirement that projectiles be so identifiable unlikely unless manufacturing methods and costs are not substantially disrupted. The method envisioned produces projectile bodies from rod or wire stock by encasing identification tag material, and swaging a projectile body with a wholly or partially encased tag with indicia. The stock may be extruded around premade identification tags or a recess may be reverse extruded in each slug. The tags may have repeated indicia in each projectile and some indicia may be accessible from the outside of a completed round of ammunition. The swaging process retains the identification tags which are protected by the body of the projectile for recovery after the projectile is used.

The end effect is that each panel only has two active states (neutral and positive deflection). Thus, a solenoid and a return spring may be used to control the canards. Additionally, the control panels may fold along the surface of the projectile, which frees up internal volume and minimizes the length of the control section.

  • Patent number: 8783184
    Abstract: A cartridge for a firearm has a bullet that defines an internal chamber. The chamber has a broader top portion than a lower portion. The bullet further defines a channel passage leading out of the top end of the bullet. The bullet contains an arrowhead slidable engaged within the channel passage. A shaft is connected to the arrowhead and passes down from the arrowhead into the lower portion of the chamber. A thrust plate is connected to the shaft end in the chamber. The thrust plate is spring metal and when the cartridge is fired, the thrust plate rises pushing the arrowhead so that it extends from the leading end of the bullet. When the thrust plate rises to the second portion of the chamber, it springs open to prevent subsequent downward motion of the thrust plate and consequently prevents subsequent retraction of the arrowhead during flight and after impact.

  • Patent number: 8689692
    Abstract: A method for operating a guided munition with a switchable fuze arrangement includes launching the guided munition towards a target. During flight of the guided munition, images are provided to a remote operator, who supplies a switching input. Responsive to said switching input, the fuze arrangement is switched to either of at least two of the following states: a delayed detonation state in which detonation of the explosive charge is delayed by a time delay after impact of the guided munition, an impact detonation state in which detonation of the explosive charge occurs on impact of the guided munition, a proximity detonation state in which detonation of the explosive charge is triggered by a proximity sensing arrangement, and a disabled state in which the guided munition functions as a guided kinetic shell without detonation of the explosive charge.
