Abstract
A fragmentation projectile having at least two adjacent casings including an inner casing having an inner surface and an outer surface, and at least one outer casing substantially surrounding the outer surface of the inner casing. An explosive charge is disposed within the inner casing, and an incendiary mass is disposed on the inner surface of the inner casing and facing the explosive. Structured zones are defined on the inner casing and include regions of lesser wall thickness than the portions of the inner casing surrounding the regions to cause a shock wave generated when the explosive charge is detonated to be transferred locally into the at least one outer casing to produce fragments of a predetermined size and shape.
Claims15
A fragmentation projectile comprising:
- at least two adjacent casings including an inner metal casing having an inner surface and an outer surface, and at least one outer metal casing substantially surrounding said inner casing;
- an explosive charge disposed within said inner casing;
- an incendiary mass disposed on said inner surface of said inner casing and facing said explosive;
- and
- structured zone means, disposed on said outer surface of said inner casing and including regions of lesser wall thickness than the portions of said inner casing between said regions, for causing a shock wave generated when said explosive charge is detonated to be transferred locally into said at least one outer casing to produce fragments of a predetermined size and shape.
A fragmentation projectile comprising:
- at least two adjacent casings including an inner casing having a substantially constant wall thickness, an inner surface and an outer surface, and at least one outer casing substantially surrounding said inner casing;
- an explosive charge disposed within said inner casing;
- an incendiary mass disposed on said inner surface of said inner casing and facing said explosive;
- structured zone means, disposed on said outer surface of said inner casing and including regions of lesser wall thickness than the portions of said inner casing between said regions, for causing a shock wave generated when said explosive charge is detonated to be transferred locally into said at least one outer casing to produce fragments of a predetermined size and shape, said structured zone means comprise a pattern of grooves, which have a sawtooth shape in cross-section, formed in said outer surface of said inner casing, said pattern of grooves including a plurality of said grooves extending diagonally to a longitudinal axis of said projectile such that said portions of said inner casing between said regions or lesser wall thickness have a substantially diamond shape at said outer surface of said inner casing.
A fragmentation projectile comprising:
- at least two adjacent casings including an inner casing having an inner surface and an outer surface, and at least one outer casing substantially surrounding said inner casing;
- an explosive charge disposed within said inner casing;
- an incendiary mass disposed on said inner surface of said inner casing and facing said explosive;
- structured zone means, disposed on said outer surface of said inner casing and including regions of lesser wall thickness than the portions of said inner casing between said regions, for causing a shock wave generated when said explosive charge is detonated to be transferred locally into said at least one outer casing to produce fragments of a predetermined size and shape;
- and
- a further casing disposed on and surrounding the outer surface of said at least one outer casing.
