Abstract

In one embodiment, a less lethal munition including a ring airfoil projectile. The flight trajectory of the projectile has increased accuracy resulting from the aerodynamic stabilization of the projectile. In some embodiments, the projectile is both aerodynamically stabilized and spin stabilized.

Claims

1. A munition for a gun having a barrel, comprising:

a frangible retainer;

a sabot;

a projectile having an outer diameter that is less than the diameter of the barrel, said projectile being held in compression between said retainer and said sabot; and

a body for supporting said sabot and said retainer, said body including at least a portion of a chamber for receiving compressed gas and at least one passageway for directing gas from said chamber to said sabot, said body further including a threaded surface for connection to an interchangeable base.

2. The munition of claim 1 wherein said body and said retainer are threadably coupled.

3. The munition of claim 1 wherein said sabot is in sliding contact with said body.

4. The munition of claim 1 wherein said body includes a centrally located concave chamber and a plurality of gas passageways extending radially outward from said chamber.

5. The munition of claim 1 wherein said body has an outer diameter adapted and configured for sealing contact with the bore of the barrel.

6. The munition of claim 1 wherein said sabot has an outer diameter adapted and configured for sealing contact with the bore of the barrel, the outer diameter of said sabot being greater than about 35 mm and less than about 43 mm.

7. The munition of claim 1 wherein said retainer, said sabot, and said projectile are fabricated from a polymer.

8. The munition of claim 1 which further comprises a base having a threaded surface for coupling to the threaded surface of said body, said base including a primer, said base being adapted a configured for a non-automatic gun.

9. The munition of claim 1 which further comprises a base having a threaded surface for coupling to the threaded surface of said body, said base including a telescoping member having a primer, said base and said telescoping member being adapted a configured for an automatically reloading gun.
