| 20080315032 | Techniques for providing surface control to a guidable projectile - A guidable projectile has a central shaft, a projectile body, and a surface control assembly. The projectile body is arranged to rotate around at least a portion of the central shaft during flight of the guidable projectile to provide stabilization. The surface control assembly is supported by the central shaft. The surface control assembly includes a movable member arranged to control a trajectory of the guidable projectile during flight of the guidable projectile, and an electromagnetic actuator interconnected between the central shaft and the movable member. The electromagnetic actuator is arranged to control movement of the movable member relative to the central shaft. | 12-25-2008 |

| 20100213307 | Hybrid spin/fin stabilized projectile - A hybrid spin/fin stabilized projectile. The novel projectile includes a body, a first mechanism for spin stabilizing the body during a first mode, and a second mechanism for fin stabilizing the body during a second mode. In an illustrative embodiment, the projectile includes a rifling band adapted to engage with rifling in a gun during gun launch to impart a spin rate compatible with spin stabilization to the projectile, and a plurality of folding fins attached to an aft end of the body. A fin locking mechanism locks the fins in an undeployed position during the first mode and unlocks to deploy the fins at a predetermined time to switch the projectile to fin stabilization during the second mode. The projectile also includes a mechanism for reducing the spin of the projectile to a rate compatible with guided flight during the second mode. | 08-26-2010 |
| 20120248239 | STEERABLE SPIN-STABILIZED PROJECTILE - A spin-stabilized projectile has a collar around the middle of its spun fuselage, longitudinally spanning a center of mass of the projectile. The collar includes lift-producing aerodynamic surfaces. Positioning the collar relative to the spinning fuselage produces a direct lift force on the projectile that may be used to steer the projectile. Since the projectile is constantly spinning, the positioning may be accomplished by a brake, such as a magnetic brake or a fiction brake, that allows the collar to be positioned substantially fixed relative to inertial space, with the collar not rotating with the fuselage about a longitudinal axis of the projectile. Since the lift force is applied close to the center of mass of the projectile, the steering occurs with no substantial change in the angle of attack of the projectile. | 10-04-2012 |
| 20140077024 | Spin or Aerodynamically Stabilized Ammunition - The disclosure relates to spin-stabilized ammunition for use in grooved or smooth bore handheld firearms with calibers up to 60 mm. The projectile of the ammunition features: a body in the shape of a truncated cone at the top of a cylinder with proportions of the cone length to the cylinder length varying between from one-to-six to one-to-three depending on the expected initial speed of the projectile after the ammunition has been discharged; a central longitudinal barrel through the projectile with a proportion of the entrance diameter and exit diameter of 1.38-to-one for expected discharge speeds near sound velocity or of 1.22-to-one for expected discharge of hypersonic velocities; nozzles for the creation of a spinning motion of the ammunition around the projectile's axis, the nozzle being located between cavities for propellant charges. | 03-20-2014 |
