Perforating ammunition
View Patent ↗A perforating ammunition having a penetration body delimiting an internal cavity closed by a base which penetration body includes a front nose with at least one insert integral with the nose, the insert being a material denser than that of the body and arranged in a housing opening to the outside of the body.
1. A perforating ammunition comprising a penetration body delimiting an internal cavity closed by a base, wherein said penetration body comprises a material having a limit of elasticity greater than or equal to 1,200 Mega Pascals and comprises a front nose comprising inserts integral with said nose, said inserts comprising a material with high mechanical properties, denser than that of said body and arranged in a housing opening to the outside of said body, where said inserts are arranged radially around an axial extension of said body, said inserts being integrally connected to said body by linking means.
2. A perforating ammunition according to claim 1 , wherein said linking means comprises at least one ring surrounding the inserts.
3. A perforating ammunition according to claim 1 wherein said ammunition comprises a nose comprising a dense alloy located at the end of said axial extension of said body and having a rear surface pressing on said segments.
4. A perforating ammunition according to claim 1 , wherein each of said inserts comprises a substantially cylindrical bar housed in a bore in said penetration body.
5. A perforating ammunition according to claim 4 , wherein said ammunition comprises a single axial insert having a front nose extending said penetration body.
6. A perforating ammunition according to claim 5 , wherein said ammunition comprises a propellant powder charge enabling said one insert to be ejected from said penetrating body.
7. A perforating ammunition according to claim 5 , wherein said ammunition comprises at least one crown of bars evenly spaced around an axis of said penetration body.
8. A perforating ammunition according to claim 7 , wherein said ammunition comprises two crowns of bars evenly spaced around an axis of said penetration body.
9. A perforating ammunition according to claim 7 , wherein the ends of said bars are flush with an external surface of said penetration body.
10. A perforating ammunition according to claim 7 , wherein the ends of said bars protrude from said penetration body.
11. A perforating ammunition according to claim 10 , wherein each of said bars has its axis inclined with respect to the axis of the penetration body.
12. A perforating ammunition according to claim 8 , wherein the ends of the bars of said crowns lie substantially in the same plane.
13. A perforating ammunition according to claim 1 , wherein said internal cavity encloses at least one explosive charge.
