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.
Claims29
A munition for a weapon, comprising:
- a ring airfoil projectile adapted and configured for explosive release from a weapon, said projectile including a wall surrounding an inner flowpath and a centerline, the wall being symmetric about the centerline, the wall having an outer surface, an inner surface defining the boundary of the inner flowpath, and a cross-sectional shape, the inner surface of the cross-sectional shape being more cambered than the outer surface of the cross-sectional shape.
