  • Patent number: 9778005
    Abstract: The present invention relates to stackable projectiles having a warhead and a propulsion unit. An adaptor enables the warhead to be coupled to propulsion units made of different materials. Furthermore, an adaptor couples different profiles of warheads and propulsion units and allows projectiles to be stacked without need for design modifications. The assembled projectile can be fired electrically or mechanically.

  • Patent number: 9448026
    Abstract: Projectiles with sealed propellant are described herein. In one embodiment of the invention, a projectile includes a body having a nose portion and a tail portion, a plurality of propellant charges contained within the body, a plurality of selectable initiators contained within the body for ignition of respective propellant charges, one or more ports for exit of ignition gases produced by the charges for propulsion of the projectile from the weapon, and one or more inductors for inducing a firing current, where at least one initiator only initiates on receiving a firing current which is different from the firing signal required to initiate the other initiators.
