초록 ▼

A dual operating mode warhead comprises a generally cylindrical explosive charge having a longitudinal axis and an outer peripheral surface extending between front and rear facing initiation surfaces. A front detonator initiates peripheral detonation of the explosive charge at the front facing initiation surface and creates a detonation wave travelling through the explosive charge toward the rear facing initiation surface. A rear detonator initiates detonation of the explosive charge at the rear facing initiation surface and creates a detonation wave travelling through the explosive charge and toward the forward facing initiation surface. Against heavy armor, only the rear initiation is used. A precision shaped charge proximate the front facing surface is responsive to the rear detonation wave to produce a high speed forward travelling jet with excellent armor piercing capability. Against softer targets, a fragmentation case proximate the outer peripheral surface of the explosive charge is responsive to operation of both the first and second detonation waves to produce a radially directed planar sidespray pattern. With this construction, actuation of the rear detonator alone results in an armor piercing mode of operation whereas near simultaneous actuation of both detonators results in a wider area of impact of the forward focused energy and in an enhanced sidespray fragmentation. Timing of initiation of the two detonators will be optimized specifically for any design application.

A dual operating mode warhead comprising: an axially symmetric explosive charge having a longitudinal axis and an outer peripheral surface extending between a front facing initiation surface and a rear facing initiation surface, said front facing initiation surface and said rear facing initiation surface both lying in planes transverse of said outer peripheral surface; first detonating means for initiating detonation of said explosive charge at said front facing initiation surface and creating a first detonation wave for travelling through said explosive charge toward said rear facing initiation surface; and second detonating means for initiating detonation of said explosive charge at said rear facing initiation surface and creating a second detonation wave for travelling through said explosive charge toward said forward facing initiation surface; shaped lined charge means shaped for penetration of armor or hard target material proximate said front facing initiation surface and responsive to the second detonation wave to produce a high speed forward traveling jet with armor piercing capability; and a fragmentation case having a fracture grid construction proximate said outer peripheral surface and intermediate said front facing initiation surface and Said rear facing initiation surface; whereby actuation of said second detonating means alone results in maximum armor penetration of a target; and whereby substantially simultaneous actuation of said first and second detonating means results both in armor penetration of the target and in a radially directed sidespray pattern of fragmentation of said fragmentation case against the target.
