Steerable projectile with a rotatable nose cone having a flat formation extending off-axis from the tip of the nose

摘要

A steerable bullet 30 comprises a cylindrical body portion 32 and a nose portion 34. The body 32 and nose 34 are substantially coaxially arranged and rotatable relative to one another about their co-axis. The nose 34 further comprises an asymmetric formation 36 operable to enable the bullet 30 to be subjected to off-axis drag during flight. The nose 34 may be ellipsoidal in profile, with a flat formation extending off-axis from the tip of the nose. In use, the bullet 30, on expulsion from a gun barrel, will rotate about its elongate axis. The nose 34 may counter rotate relative to the body 32 during flight by means of DC motor (46,Fig.4). The nose may thus be rendered stationary with respect to the ground such that the asymmetric formation 36 can impart a steering force onto the bullet 30. Rotation of the nose 34 may be controlled by control electronics (42,Fig.4) which may act on information received from an optical detection system 40 and a laser guidance means.
