Ring airfoil glider with augmented stability

A method for launching a ring airfoil projectile, comprising:

• providing a ring-shaped projectile having and outer diameter, the wall of the projectile having the cross-sectional shape of an airfoil, the projectile having a center of gravity, the projectile having an aerodynamic center of pressure;
• propelling the projectile within the weapon;
• spinning the projectile as it travels within the weapon;
• and
• aerodynamically stabilizing the projectile by placing the center of pressure behind the center of gravity.

A munition for a weapon, comprising:

• a 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 flowpath, and a cross-sectional shape, the inner surface being more cambered than the inner surface;
• a support member for positioning the projectile within the weapon, and
• a source of pressurized gas for propelling the projectile;
• wherein release of said source of said charge propels said projectile out the weapon.
