Abstract
Gas Projection Device that can take many external forms that simulate military munitions being exploded and that contain features that enhance the sound of the explosion and the appearance of smoke and attendant percussion. Such device can be controlled by many different means including electronic remote control.
Claims31
A gas projector device comprising a substantially air tight barrel or chamber which contains at least one exit port through the wall of the barrel, the passage through which is controlled by a valve, which may be a burst disk, that can open substantially instantaneously, and a gas that is at a pressure substantially greater than the ambient pressure outside the barrel, and when the said valve opens substantially instantaneously, the said gas that is at pressure in the barrel, is released through such valve, and collides with the ambient air outside the barrel, and does so with sufficient force to cause a sonic report, and the remaining gas in the barrel, entrains some or all payload material matter that may be located within the barrel, and transports it out of the barrel, through the said valve.
A gas projector device comprising a substantially air tight barrel which contains:
- at least one exit port through the wall of the barrel, the passage through which is controlled by a valve, which can be a burst disk, that can open substantially instantaneously, and a gas that is at a pressure substantially greater than the ambient pressure outside the barrel, and a vortex generator proximal to the exit port and said valve, such that one or more vortexes are created by the vortex generator when said gas is released substantially instantaneously by said valve, creating a pulse of gas that is suitable for the creation of a vortex, when passed through that particular vortex generator, and such vortexes may carry payload, away from the device, and or create percussive impacts that can be perceived by persons that are in their path.
