Abstract
The present embodiments provide apparatuses for use in launching an inhibiting powder. These embodiments comprise a source of impulse pressure that induces a propellant pressure, a barrel cooperated with the source of impulse pressure to receive the propellant pressure, inhibiting powder positioned within an interior of the barrel, a burst diaphragm secured between the source of the impulse pressure and the inhibiting powder, and an actuator that activates the source of impulse pressure to deliver an expanding gas producing an increasing pressure that is applied to the burst diaphragm where the burst diaphragm bursts when the applied pressure exceeding a burst threshold, resulting in a release of the propellant pressure into the barrel to drive the inhibiting powder from the barrel in substantially an aerosol form generating a cloud of inhibiting powder.
