Abstract
A statically stable limited range projectile utilizes a fin assembly combd with a cylindrical body and low drag ogival front end to ballistically match the limited predetermined range flight characteristics of a standard round.
Claims3
A statically stable limited range projectile which comprises:
- fin means for generating projectile yaw to limit said projectile's range, which includes:
- a cylindrically shaped body member having an axially aligned boss at a front end thereof;
- spin dampening and aerodynamic means for giving said projectile static stability for a limited range and for inducing yaw resonance at a particular spin rate subjecting said projectile to unstable flight, high drag, and limiting said projectile to a predetermined maximum range;
- said spin dampening and aerodynamic means includes canted equally spaced fins disposed on a rear end of said cylindrically shaped body member which generate a spin rate to enable said projectile to attain resonance spin rate when said projectile is fired from a smooth bore weapon, said canted fins having a fin assembly fin base end having an oval cylindrically shaped counter bore therein axially aligned with a longitudinal axis of said projectile;
- and
- ogive shaped body means fixedly attached to said front end of said fin means for giving said projectile the flight characteristics of a standard round up to 200 meters and has a maximum range which does not exceed 500 meters, which includes;
- a rear end having an axially aligned bore therein holding said body member boss operatively thereto.
