A non-explosive acoustic source utilizes the combustion of aluminum and water to generate an acoustic pulse. The operation of the non-explosive acoustic source relies on a water/aluminum reaction to generate a burst pressure. The source may be deployed as a single charge or as one element of a multiple charge array and is configurable to explode at variable depths with variable energy levels. The inherent safety of the non-explosive acoustic source obviates the necessity for auxiliary safety features or procedures to protect against inadvertent explosion. As a result, the non-explosive acoustic source facilitates the implementation of sonic detection systems and reduces the operational costs associated with such systems.

What is claimed is: 1. A non-explosive acoustic source comprising: a confinement tube including apertures at opposing ends thereof and a combustion chamber located between the opposing ends, wherein the combustion chamber includes aluminum powder; a first end plug located in a first aperture of the confinement tube, wherein the first end plug includes means for permitting the entry of water into the confinement tube at a specific water pressure; a second end plug located in a second aperture of the confinement tube opposite the first aperture, wherein the second end plug includes a detonator. 2. A non-explosive acoustic source as claimed in claim 1, wherein the means for permitting entry of water into the confinement tube comprises a burst disk. 3. A non-explosive acoustic source as claimed in claim 2, wherein the means for permitting entry of water into the confinement tube further comprises a ball valve unit. 4. A non-explosive acoustic source as claimed in claim 1, wherein the confinement tube includes a weak point designed to fracture when subjected to a predetermined internal pressure. 5. A non-explosive acoustic source as claimed in claim 1, wherein at least one of the end plugs is designed to shear at a predetermined internal pressure.
