Abstract

A projectile for piercing armor includes an outer jacket built around a penetrator assembly. The penetrator assembly includes an inner jacket, a penetrator, and an incendiary charge. The inner jacket includes a leading part and a trailing part. The incendiary charge is carried by the leading part of the inner jacket. The penetrator is made of an armor-piercing material and includes an armor-piercing leading extremity, a trailing extremity, and an outer surface. The armor-piercing leading extremity extends into the trailing part of the inner jacket, and the inner jacket bears against the outer surface of the penetrator between the armor-piercing leading extremity and the trailing extremity. An empty space within the inner jacket is between the armor-piercing leading extremity of the penetrator and the incendiary charge.

Claims

1. A projectile, comprising:

a penetrator and an incendiary charge inside an outer jacket;

the penetrator includes a peripheral edge, a trailing extremity, a cylindrical main part between the peripheral edge and the trailing extremity, and a pointed armor-piercing leading extremity extending conically forwardly from the peripheral edge;

the incendiary charge is ahead of the penetrator and includes a leading surface;

the outer jacket includes a ballistic nose ahead of the incendiary charge;

the ballistic nose has a trailing nose surface in direct contact against the leading surface of the incendiary charge; and

the penetrator is behind, and is not in contact with, the incendiary charge, the cylindrical main part extends forwardly from the trailing extremity to the peripheral edge, the pointed armor-piercing leading extremity extending conically forwardly from the peripheral edge resides uncontacted within an empty space inside the outer jacket between and separating the pointed armor-piercing leading extremity and the incendiary charge, the empty space extends forwardly from the peripheral edge of the penetrator, and an inner surface of the outer jacket bears against an outer surface of the cylindrical main part thereby holding the penetrator to the outer jacket.

2. The projectile according to claim 1, wherein the penetrator and the incendiary charge are centered about a longitudinal axis of the outer jacket.

3. The projectile according to claim 1, wherein the outer jacket is made of a material selected from a group of copper, cupronickel, tombac, and tombac-plated steel.

4. The projectile according to claim 1, wherein the penetrator is made of an armor-piercing material.

5. The projectile according to claim 4, wherein the armor-piercing material is selected from a group of hardened steel, tungsten, tungsten carbide, and depleted uranium.

6. The projectile according to claim 1, wherein the incendiary charge is a non-explosive incendiary composition.

7. The projectile according to claim 1, wherein the incendiary charge is carried by an inner jacket inside the outer jacket.

8. The projectile according to claim 7, wherein the inner jacket defines a leading volume and a leading edge encircling a leading opening to the leading volume, the incendiary charge is in the leading volume, and the leading surface of the incendiary charge is proximate to the leading opening to the leading volume.

9. The projectile according to claim 8, wherein the trailing nose surface is in direct contact against the leading edge of the inner jacket.

10. The projectile according to claim 8, wherein the inner jacket is made of a material selected from a group of stainless steel and aluminum.

11. A projectile, comprising:

a penetrator and an incendiary charge inside an outer jacket;

the penetrator includes a peripheral edge, a trailing extremity, a cylindrical main part between the peripheral edge and the trailing extremity, and a pointed armor-piercing leading extremity extending conically forwardly from the peripheral edge;

the incendiary charge is ahead of the penetrator and includes a leading surface;

the outer jacket includes a ballistic nose ahead of the incendiary charge;

the ballistic nose is of solid construction and has a trailing nose surface in direct contact against the leading surface of the incendiary charge;

the penetrator is behind, and is not in contact with, the incendiary charge, the cylindrical main part extends forwardly from the trailing extremity to the peripheral edge, the pointed armor-piercing leading extremity extending conically forwardly from the peripheral edge resides uncontacted within an empty space inside the outer jacket between and separating the pointed armor-piercing leading extremity and the incendiary charge, the empty space extends forwardly from the peripheral edge of the penetrator, and an inner surface of the outer jacket bears against an outer surface of the cylindrical main part thereby holding the penetrator to the outer jacket.

12. The projectile according to claim 11, wherein the penetrator and the incendiary charge are centered about a longitudinal axis of the outer jacket.

13. The projectile according to claim 11, wherein the outer jacket is made of a material selected from a group of copper, cupronickel, tombac, and tombac-plated steel.

14. The projectile according to claim 11, wherein the penetrator is made of an armor-piercing material.

15. The projectile according to claim 14, wherein the armor-piercing material is selected from a group of hardened steel, tungsten, tungsten carbide, and depleted uranium.

16. The projectile according to claim 11, wherein the incendiary charge is a non-explosive incendiary composition.

17. The projectile according to claim 11, wherein the incendiary charge is carried by an inner jacket inside the outer jacket.

18. The projectile according to claim 17, wherein the inner jacket defines a leading volume and a leading edge encircling a leading opening to the leading volume, the incendiary charge is in the leading volume, and the leading surface of the incendiary charge is proximate to the leading opening to the leading volume.

19. The projectile according to claim 18, wherein the trailing nose surface is in direct contact against the leading edge of the inner jacket.

20. The projectile according to claim 17, wherein the inner jacket is made of a material selected from a group of stainless steel and aluminum.
