Abstract

Projectiles and projectile systems are provided herein employing an inhibiting and/or marking substance for impairing/marking a living target. In some embodiments, the systems include a first part being non-spherical and having an exterior, a plurality of stabilizing fins secured with the exterior of at the first part, and a second part have a hollow portion containing an inhibiting substance, wherein the second part is sealed with the first part to seal the inhibiting substance within at least the hollow portion. The first part can similarly have a hollow portion such that a volume is defined by the hollow portion of the first part and the hollow portion of the second part, wherein the inhibiting substance is contained within the volume. The fins can be angled to provide spin stabilizing.

Claims (34)

1. A projectile system for use in delivering a substance to a target, comprising:

a projectile comprising:

a first part;

a second part that is at least partially hollow, wherein the second part is secured with the first part to seal the hollow portion defining a volume, wherein the projectile is non-spherical;

an inhibiting substance contained within the volume; and

stabilizing fins secured with the second part along an exterior of the second part; and

a propulsion block positioned proximate to the stabilizing fins and configured to maintain substantially all of a propulsion force behind the propulsion block and to evenly distribute the propulsion force to the projectile;

wherein the inhibiting substance is dispersed into a cloud upon impact of the projectile with a target;

wherein the second part comprises a body portion removably secured with a tail portion; and

wherein the body portion tapers to a smaller diameter away from the first part and comprises a tongue, and the tail portion comprises the stabilizing fins and a receiving port that mates with the tongue of the body portion securing the body portion with the tail portion.

2. The projectile system of claim 1 , wherein the first part comprising a fill hole cooperated with the volume and a lid secured within the fill hole sealing the fill hole.

3. The projectile system of claim 2 , wherein the body portion comprises weakening features to aid in the rupture of the body.

4. A projectile system for use in delivering a substance to a target, comprising:

a projectile comprising:

a first pat;

a second part that is at least partially hollow, wherein the second part is secured with the first part to seal the hollow portion defining a volume, wherein the projectile is non-spherical;

an inhibiting substance contained within the volume; and

stabilizing fins secured with the second part along an exterior of the second pat and

a propulsion block positioned proximate to the stabilizing fins and configured to maintain substantially all of a propulsion force behind the propulsion block and to evenly distribute the propulsion force to the projectile;

wherein the inhibiting substance is dispersed into a cloud upon impact of the projectile with a target;and

wherein the propulsion block comprises a plate closing a first end of the propulsion block and configured to be positioned proximate the projectile, and a plurality of rings separated and positioned along a length of the block where the plurality of rings extend around a perimeter of an exterior of the propulsion block and radially away from a central axis of the propulsion block with each ring configured to establish a seal that aids in maintaining substantially all of the propulsion force behind the propulsion block and evenly distributed to the projectile.

5. The projectile system of claim 4 , further comprising:

a shell within which the projectile and the propulsion block are positioned prior to launch with the rings of the propulsion block establishing the seals against the shell.

6. The projectile system of claim 5 , wherein the propulsion block comprises a flexible lip extending radially and circumferentially about an exterior of the propulsion block, where the lip defines a diameter that is greater than a diameter of the shell when the propulsion block is external to the shell and the lip flexes when the propulsion block is positioned within the shell such that the lip establishes a seal with the shell.

7. The projectile system of claim 6 , wherein the plate extends beyond a cylindrical portion of the propulsion block and establishes a seal with the shell.

8. The projectile system of claim 7 , wherein the second part comprises a body portion removably secured with a tail portion, where the body portion tapers to a smaller diameter away from the first part and comprises a tongue, and the tail portion comprises the stabilizing fins and a receiving port that mates with the tongue of the body portion securing the body portion with the tail portion; and

the first part further comprises a fill hole cooperated with the volume and a lid secured within the fill hole closing the fill hole and the volume.

9. A projectile system for use in delivering a substance to a target, comprising:

a projectile comprising:

a first part;

a second part that is at least partially hollow and further comprises a tapered tongue, wherein the second part is secured with the first part to seal the hollow portion defining a volume, wherein the projectile is non-spherical;

an inhibiting substance contained within the volume; and

a third part comprising stabilizing fins secured along an exterior of the second part and a receiving port that mates with the tapered tongue; and

wherein the inhibiting substance is dispersed into a cloud upon impact of the projectile with a target.
