  • Publication number: 20180245895
    Abstract: A method for guiding an artillery projectile to a target. In one embodiment, the method includes providing control commands to change an angle of attack of one or more roll stabilizing fins and providing control commands to change an angle of attack of one or more lift guiding fins; and controlling the roll angle to provide a lift force to guide the projectile along a trajectory, wherein the projectile is configured to spin about its longitudinal axis during flight.

  • Patent number: 9945649
    Abstract: An apparatus and method for guiding a cannon shell accurately are disclosed. The apparatus includes two main parts adapted to be installed on the leading end of the cannon shell. The front main part of the apparatus is equipped with at least one pair of fins and is rotatable with respect to the rear main part. The pair of fins is controlled to hold the front main part substantially stable with respect to an external reference frame when the cannon shell rotates as it flies towards its target. Control system is comprised within the apparatus that receives location signals and is adapted to provide guiding control commands to the cannon shell via the fins so as to guide the shell accurately to its preprogrammed target. The control system is adapted to activate the detonation chain of the shell according to preprogrammed mode.

  • Patent number: 9587923
    Abstract: A guiding assembly is adapted to be connected to a projectile and comprising a rear main unit adapted to be connected to the front end of the projectile, and a front main unit rotatably connected at its rear end to the front end of the rear main unit. The front main unit is adapted to rotate about a central longitudinal axis. A relative speed control unit is operable between the rear main unit and the front main unit and capable of providing spin braking force to slow the relative speed of rotation of the front main unit. An at least one guiding fin radially extends from the front main unit. The pitch angle of the fin is controllable by a return spring connected to the fin so that the pitch angle of the fin is growing as the aerodynamic pressure on the fin lowers and it is growing smaller as the aerodynamic pressure on the fin gets bigger.

  • Publication number: 20110185872
    Abstract: Disclosed is a repetitive stroke work system having an upper holder assembly configured to hold one or more work performing elements deployed on the upper holder assembly. The work performing elements are configured for lockable displacement on the upper holder assembly, with the displacement being along both X and Y axis relative to the upper holder assembly. The repetitive stroke work system also includes a workpiece repetitive positioning device configured with at least one initial work stop for use while performing an initial work operation and at least one subsequent work stop for use while performing subsequent work operations. The upper holder assembly is displaceable along a Z axis so as to bring the work performing elements in to operational contact with a workpiece deployed on the workpiece repetitive positioning device.

  • Publication number: 20030039177
    Abstract: A system and method for the storage and selective retrieval of discs is described. For selective retrieval of a disc, a feed unit is positioned such that a slot is located opposite a designated disc, a gate is opened and the designated disc rolls by the force of gravity into the slot and the rolling of remaining discs are stopped by a belt and, after the selected disc is retrieved, the gate closes, returning the remaining discs into the storage position.
