Swept hemispherical profile axisymmetric circular linear shaped charge

摘要

In the hemispherical family of axisymmetric circular linear shaped charge liners, this novel swept hemispherical profile shaped explosive device produces a stable jet with the ability to aim the jet by moving the initial explosive impulse ring on the liner surface inward or outward from the pole of the liner profile. The precision of the circular simultaneous initiation of the HE billet is accomplished by the use of a novel Circular Precision Initiation Coupler (CPIC). This CPIC uses a single point initiation to create a simultaneous peripheral detonation of the HE billet that collapses and drives the swept liner into a high speed stretching hollow cylindrical projectile, or more commonly called a jet in the industry.
