1. A munition for a weapon having a barrel, comprising:
- a ring projectile symmetrical about a centerline and including a wall having a cross-sectional shape of an airfoil, the airfoil having a chord line, the inner surface of the wall defining the boundary of an inner flowpath, the chord line being non-parallel to the centerline;
a support member for positioning said projectile within the weapon, andan explosive charge for propelling said projectile;
wherein combustion of said charge propels said projectile out the barrel of the weapon.

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.

19. A munition for a weapon having a barrel, comprising:
-
a ring projectile symmetrical about a centerline and including a wall having a cross-sectional shape of an airfoil with a leading edge and a trailing edge, the airfoil having a chord line, the inner surface of the wall defining the boundary of an inner flowpath, the chord line being angled relative to the centerline such that the chord line defines an intersection point with the centerline that is aft of the trailing edge; a support member for positioning said projectile within the weapon, and an explosive charge for propelling said projectile; wherein combustion of said charge propels said projectile out the barrel of the weapon. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
