Abstract

A projectile has a body with an axis and a meplat disposed substantially orthogonal to the axis. The meplat is bounded by a substantially square edge.

Claims

1. A projectile comprising a body having an axis and a meplat disposed substantially orthogonal to the axis, wherein the meplat is bounded by a substantially square edge.

2. The projectile of claim 1, wherein the body comprises a body tail surface disposed opposite the meplat and a nose extending from the meplat towards the body tail surface, wherein the nose comprises a frustum having substantially curved surfaces.

3. The projectile of claim 2, wherein the nose terminates at a substantially round collar.

4. The projectile of claim 3, wherein the body comprises a body ogive radius and the collar comprises a collar ogive radius substantially the same as the body ogive radius.

5. The projectile of claim 3, the body further comprising a neck disposed between the collar and the body, wherein the neck comprises a diameter less than a diameter of the collar.

6. The projectile of claim 5, wherein the body defines a groove reference curve spanning from the body to the collar, wherein the groove reference curve is identical to the body ogive radius.

7. A projectile comprising a body and a nose, wherein the nose comprises a frustum and a meplat, and wherein an outer edge of the meplat is at least partially defined by a plurality of corners.

8. The projectile of claim 7, wherein the frustum comprises at least three surfaces extending from the meplat.

9. The projectile of claim 7, wherein the frustum comprises a plurality of curved surfaces extending from the meplat.

10. The projectile of claim 7, wherein the nose terminates at a collar, wherein an outer edge of the collar is at least partially defined by a circular outer edge.

11. The projectile of claim 7, wherein the projectile comprises a total projectile length and the nose comprises a nose length of about 25% to about 35% of the total projectile length.

12. The projectile of claim 11, wherein the nose length is about 27.5% of the total projectile length.

13. The projectile of claim 11, further comprising a neck connecting the body and the nose, and wherein the body and the nose define a groove substantially surrounding the neck.

14. The projectile of claim 13, wherein the neck comprises a neck length of at least about 10% of the total projectile length.

15. A projectile comprising:

an axis;

a total projectile length measured along the axis;

a nose comprising a collar;

a body having a body tail surface; and

a neck connecting the nose and the body, wherein the neck comprises a neck diameter of about 80% of a diameter of the collar, and wherein the nose and the body define a groove therebetween wherein the groove comprises a groove length of at least about 10% of the total projectile length.

16. The projectile of claim 15, wherein the nose comprises a meplat having an angular outer edge.

17. The projectile of claim 15, wherein the body comprises a body ogive radius and defines a reference curve spanning the groove, wherein the reference curve further extends from the collar to the axis, and wherein the reference curve comprises a reference curve radius identical to the body ogive radius.

18. The projectile of claim 17, wherein the nose is substantially contained within the reference curve.

19. The projectile of claim 17, wherein the nose is contained within the reference curve.

20. The projectile of claim 15, wherein the body tail surface at least partially defines a concave recess.
