Abstract
A high impulse fuze booster includes a booster explosive charge positioned within an explosive charge cavity of a booster housing. A substantially planar flyer plate is coupled with the booster housing, and a detonation waveshaper is positioned within the booster explosive charge. A low-sensitivity explosive charge is opposed to the substantially planar flyer plate. The booster explosive charge is configured to generate a detonation wave and the detonation waveshaper shapes the detonation wave into a planar detonation wave, the planar detonation wave is parallel to the substantially planar flyer plate. The planar detonation wave interacts with the substantially planar flyer plate in two or more stages including a planar striking stage and a planar contact stage where the planar detonation wave carries the substantially planar flyer plate into planar contact with a plurality of surfaces of the low-sensitivity explosive charge to initiate the low-sensitivity explosive charge.
