Hingeable ogive projectile
Embodiments of the hingeable ogive projectile disclosed herein include a projectile comprising a nose portion comprising a plurality of slits, the plurality of slits being cut from an outer surface of the nose portion to a central cavity of the nose portion and an open space formed in a meplat at a distal end of the nose portion. The hingeable ogive projectile disclosed herein may be configured to switch from a non-deformed configuration during firing and a deformed configured upon impact with a target. Longitudinal compression of the nose portion causes the nose portion to expand radially and causes a plurality of petals to form from material in the nose portion between consecutive slits. Radial expansion and longitudinal compression of the nose portion cause buckling of a plurality of petals at a hinge point on each of the plurality of petals.
1. A projectile comprising:
a projectile body comprising:
a nose portion, located distally on the projectile, the nose portion comprising a plurality of slits, the plurality of slits being cut from an outer surface of the nose portion to a central cavity of the nose portion;
a rear portion, located proximally on the projectile; and
an open space formed in a meplat at a distal end of the nose portion around which the meplat forms a tapered ring, the tapered ring being tapered inwardly from a proximal portion to a distal portion.
2. The projectile of claim 1 , wherein the nose portion is formed of a monolithic section of material.
3. The projectile of claim 1 , wherein the rear portion is a solid, unslit region comprising copper.
4. The projectile of claim 1 , wherein a flat surface perpendicular to the direction of firing is formed on a distal end of the rear portion.
5. The projectile of claim 1 , wherein a stepdown region is formed at the junction of the rear portion and the nose portion.
6. The projectile of claim 1 , wherein a diameter to length ratio of the projectile is 1:5.
7. The projectile of claim 5 , wherein the stepdown region is configured to stop compression of the projectile during impact with a target.
8. The projectile of claim 1 , wherein the plurality of slits are positioned circumferentially about the nose portion.
9. The projectile of claim 6 , wherein each of the plurality of slits is a longitudinal extension formed parallel to the direction of firing.
10. The projectile of claim 1 , wherein impact with a target causes longitudinal compression of the nose portion of the projectile.
11. The projectile of claim 10 , wherein longitudinal compression of the nose portion causes the nose portion to expand radially and causes a plurality of petals to form from material in the nose portion between consecutive slits.
12. The projectile of claim 11 , wherein radial expansion and longitudinal compression of the nose portion cause buckling of the plurality of petals at a hinge point on each of the plurality of petals.
13. The projectile of claim 1 , wherein a distal petal portion forms an angle of between 50 and 70 degrees with respect to the longitudinal axis following impact with a target.
14. The projectile of claim 1 , wherein a proximal petal portion forms an angle of between 135 and 160 degrees with respect to the longitudinal axis following impact with a target.
15. The projectile of claim 12 , wherein after impact the petals remain joined at the distal end.
16. A projectile comprising:
a projectile body comprising:
a nose portion, located distally on the projectile, the nose portion comprising a plurality of slits, the plurality of slits being cut along their length from an outer surface of the nose portion to an inner hollow core of the nose portion;
a rear portion, located proximally on the projectile; and
a closed distal end not including slits,
wherein impact with a target causes longitudinal compression of the nose portion of the projectile,
wherein longitudinal compression of the nose portion causes the nose portion to expand radially and causes a plurality of petals to form from material in the nose portion between consecutive slits,
wherein radial expansion and longitudinal compression of the nose portion cause buckling of the plurality of petals at a hinge point on each of the plurality of petals.
17. The projectile of claim 16 , wherein a distal petal portion forms an angle of between 60 and 80 degrees with respect to the longitudinal axis following impact with the target.
18. The projectile of claim 16 , wherein a proximal petal portion forms an angle of between 135 and 160 degrees with respect to the longitudinal axis following impact with the target.
19. The projectile of claim 16 , wherein after impact the petals remain joined at the distal end.
20. A projectile comprising:
a projectile body comprising:
a nose portion, located distally on the projectile, the nose portion comprising a plurality of slits, the plurality of slits being cut from an outer surface of the nose portion to a central cavity of the nose portion;
a rear portion, located proximally on the projectile; and
an open space formed in a meplat at a distal end of the nose portion around which a solid, unslit section is formed extending about a circumference at the distal end of the nose,
wherein a stepdown region is formed at the junction of the rear portion and the nose portion and is configured to provide a reduced outside diameter of the projectile between the rear portion and the nose portion.
