1. A stun grenade comprising:
- a canister;
a compressed gas source installed within the canister supporting gas flow at a predetermined minimum rate;
an inflatable bag having a target pressure and a target volume to initiate a shock wave of an intensity selected to achieve a minimum noise intensity at a prescribed distance upon rupture;
the inflatable bag incorporating a seam which parts at a tension and extension occurring at the target pressure and target volume to produce the rupture;
a conduit connecting the compressed gas source to the inflatable bag;
the compressed gas source supporting gas flow to the inflatable bag through the conduit at a predetermined minimum rate to achieve the target pressure and volume for parting the seam within a fixed period;
a valve in the conduit for controlling discharge of gas through the conduit from the compressed gas source to the inflatable bag; and
a manually actuated external trigger installed on the canister to activate the valve to discharge gas to the inflatable bag.

Abstract
A stun grenade that provides a flash and an associated loud report without use of pyro-ignition sources. The flash is generated by discharge of a conventional flash bulb. The loud, explosive noise comes from rupturing of an inflatable bag at a predetermined rupture pressure and inflation volume.

6. A grenade simulator comprising:
-
a housing; a compressed gas source installed in the housing; an inflatable bag incorporating a seam which parts abruptly along its length upon inflation of the inflatable bag past a predetermined minimum size and internal pressure selected to generate a shock wave producing a minimum noise level at a prescribed distance; a delivery control conduit for discharging of gas from the compressed gas source to the inflatable bag; the compressed gas source supporting gas flow to the inflatable bag through the delivery control conduit at a predetermined minimum rate to achieve the predetermined minimum size and internal pressure for rupturing within a period; and a manual trigger installed on the housing, actuation of which causes the discharge of gas by the delivery control conduit to the inflatable bag. - View Dependent Claims (7, 8, 9, 10)
