ABSTRACT:
A boosting device including a thin, cylindrical shell of high explosive, such as PETN, which may be formed by a spiral wrap of detonating cord. The shell is formed around an inert core which is either a solid cylindrical body, a hollow cylindrical body or a web-like structure having radial spokes or a hollow center. Detonation of the shell is initiated at one point on the shell, and the detonation proceeds along opposite sides of the cylindrical shell to a point diametrically opposite the initiation point where the detonation fronts meet thereby producing a shock reinforcing effect. The shock reinforcing effect allows a relatively small amount of explosive to initiate even low sensitivity blasting agents.
