The method of operation of this weapon is by discharging a blank
cartridge into a diverging nozzle, the pressure accelerates
a gas cylinder at high mach number and atmospheric pressure
into a stationary gas. An incapacitating agent is injected into
the supersonic jet stream and spin within the vortex mixes and
activates the agent in flight. On impact the agent is deposited
onto a target. The effect can be synchronized to resonate with
body organs, to magnify the force felt by the target.
The weapon has demonstrated its capability to
knock-down a 75kg man-sized mannequin from a distance of 10
meters. Military application of a Vortex Ring Gun system will
operate at combat ranges beyond 20 meters. Candidate platform
for the Vortex Ring Gun is GL-6 repeating revolver 40-mm grenade
launcher. The concept is to provide a two piece kit that retrofits
to the gun and enables quick conversion between lethal and non-
lethal modes of operation.
The kit consists of a set of blank cartridges
and a disposable rod which slides into the barrel and affixes
to the muzzle. A second candidate platform for modification
to non-lethal operations using vortex technology is the MK19-3
automatic 40-mm grenade launcher. Firing in resonance with body
parts (10 shots/sec) amplifies the force felt by a target.
