ABSTRACT:
A waterproofed explosive charge is suspended within a frangible, spherical shell containing an aqueous solution. The assembly is dropped from an airplane or helicopter towards a fire below. Either a shock-actuated percussion cap or a fuse-ignited detonation cap activates the explosive charge at the appropriate moment and the resultant explosion creates a vapor-like fog. A portion of the combustion-supporting oxygen is displaced by the fog droplets. The minute water droplets also absorb heat energy, thereby lowering surrounding air and fuel temperatures. These effects, coupled with the concussive shock wave, act to snuff the fire.
