Abstract:
1. An acoustically efficient vortex cannon comprising: a combustion chamber; a fuel source; an oxidizer source; a purge gas source; at least one valve for delivery of fuel from the fuel source to the combustion chamber; at least one valve for delivery of either oxidizer or purge gas from the oxidizer and purge gas sources to the combustion chamber; an ignition source for the combustion chamber for initiating detonation of fuel and oxidizer; an outlet from the combustion chamber; a conical pulse guide coupled to said outlet; a secondary pulse guide spaced radially outside of said conical pulse guide, said secondary pulse guide substantially surrounding an outer surface of said conical pulse guide; and a throat directly coupled to the outlet of the combustion chamber and an inlet of the conical pulse guide, wherein said conical pulse guide has a muzzle, the conical pulse guide being fluidically coupled to the outlet from the combustion chamber, said secondary pulse guide also being fluidically coupled to the outlet from the combustion chamber; and a mouth from the secondary pulse guide located radially outside the muzzle and oriented to elect gas radially outwardly from a center line through the muzzle.
