Abstract
A sub-projectile carrier which uses aerodynamic drag to delay the release of a payload in a tailorable manner to control the spread of the payload over a desired range. A 40 mm shotgun style cartridge is shown for use for counter unmanned aerial systems, and for short range anti-personnel applications.
Claims22
A gunshot delivery system round comprising:
- a payload containment device which comprises
- a carrier which pulls off of its payload to release it,
- due to aerodynamic drag acting upon the carrier, thereby increasing the time and distance from launch where the payload is released to reduce its dispersion, wherein the round is a sub caliber projectile comprising multi-piece sabots which feature a groove (201) to retain a lid which contains the payload inside of the carrier, and which lid is released after launch of the round solely due to aerodynamic forces opening up the sabots, and wherein only release of said lid thereafter allows the payload to be released.
