Creation of directed underwater explosion

Eastern-European Journal of Enterprise Technologies, 2015
To create a shock wave with a flat or concave spherical front, the explosive is formed as a spiral with a constant or variable pitch and radius of the spiral winding. Then, the propagation velocity of the blast wave becomes smaller than the propagation velocity of the detonation wave, and the velocity of the blast wave can be varied by both a pitch ...
