Projectile
Embodiments of a projectile are disclosed herein. According to various embodiments, a projectile includes a substantially solid core of a material, and two or more petals attached to the core. The two or more petals can be formed from the same material used to form the core and can include a trocar tip. A cavity can be bound by the core and inner surfaces of the plurality of petals.
1. A projectile comprising:
a substantially solid core of a material;
a plurality of petals attached to the core and formed from the material, each of the plurality of petals comprising a trocar tip; and
a cavity that is located proximate to the core and inner surfaces of the plurality of petals, wherein the projectile is configured to deform by at least one of the plurality of petals pivoting outwardly relative to the cavity.
2. The projectile of claim 1 , wherein the projectile does not deform when engaging wood, and wherein the projectile deforms when engaging animal tissue or human tissue.
3. The projectile of claim 1 , wherein the projectile does not deform when engaging glass, and wherein the projectile deforms when engaging animal tissue or human tissue.
4. The projectile of claim 1 , wherein the plurality of petals comprises eight petals.
5. The projectile of claim 1 , further comprising a plurality of channels that define the plurality of petals.
6. The projectile of claim 5 , further comprising a groove formed on the projectile.
7. The projectile of claim 1 , wherein the material comprises a copper alloy.
8. The projectile of claim 1 , wherein the projectile is formed from a single piece of a copper alloy.
9. The projectile of claim 1 , further comprising notches to encourage deformation of the material at the notches.
10. The projectile of claim 1 , further comprising a dimple formed in the material to encourage deformation of the material at the dimple.
11. The projectile of claim 10 , wherein the dimple comprises a perforation that passes through the material to allow pressure in the cavity to escape through the plurality of petals.
12. The projectile of claim 1 , wherein the core comprises a point.
13. A projectile comprising:
a core of a material;
a plurality of petals attached to the core, the plurality of petals being formed from the material and at least one of the plurality of petals comprising a trocar tip; and
a cavity that is located proximate to the core and inner surfaces of the plurality of petals, wherein the projectile is configured to deform by the at least one of the plurality of petals pivoting outwardly relative to the cavity.
14. The projectile of claim 13 , wherein the projectile is formed from a single piece of material.
15. The projectile of claim 13 , wherein the core comprises one third of a total mass of the projectile, and wherein the plurality of petals comprise two thirds of the total mass of the projectile.
16. The projectile of claim 13 , wherein the plurality of petals comprises eight petals, and wherein the material comprises a copper alloy.
17. The projectile of claim 13 , wherein the projectile further comprises two grooves formed on an outer surface of at least one of the plurality of petals.
18. A projectile comprising:
a core of a material;
a plurality of petals attached to the core and formed from the material, each of the plurality of petals comprising a trocar tip, an outer surface, and an inner surface; and
a cavity that is defined by the core and inner surfaces of the plurality of petals, wherein the projectile is configured to deform by at least one of the plurality of petals pivoting outwardly relative to the cavity.
19. The projectile of claim 18 , wherein the plurality of petals comprises eight petals, and wherein the material comprises a copper alloy.
20. The projectile of claim 18 , wherein the projectile further comprises two grooves formed on an outer surface of at least one of the plurality of petals.
