Abstract
A method for initiating a low-sensitivity explosive charge includes initiating a booster explosive charge within an explosive charge cavity in a booster housing, and generating a planar detonation wave. Generating the planar detonation wave includes directing a detonation wave through the booster housing along a first waveshaper surface of a detonation waveshaper. The detonation wave is directed around the first waveshaper surface toward a second tapered waveshaper surface. After progressing around the first waveshaper surface, the detonation wave is directed along the second tapered waveshaper surface. The detonation wave changes into a planar detonation wave as the detonation wave moves along the second tapered waveshaper surface, the planar detonation wave includes a planar wave front. The planar detonation wave strikes a flyer plate coupled over the explosive charge cavity of the booster housing, and the planar wave front makes planar contact along an inner face of the flyer plate.
