Axial flux machine for use with projectiles
A powered projectile having a nose portion, a body portion, a tail portion, and a central axis. In various embodiments a collar is rotatably mounted to a control support portion with a plurality of aerodynamic surfaces thereon for despinning the collar. An alternator configured as an axial flux machine with a stator arranged can be axially adjacent to one or more rotors, the stator including a plurality of windings and the one or more rotors each including a plurality of permanent magnets arranged about the face of the respective one or more rotor. In various embodiments the projectile includes an assembly of projectile control circuitry. In one or more embodiments, upon relative motion of the rotor with respect to the stator, magnetic flux from the magnets interacts with the windings of the stator and passes through an air gap between the one or more rotors and stator.
TRAJECTORY SHAPING
The presently disclosed subject matter includes a system and a method for launching a projectile towards a target, wherein the system comprises a control circuitry, a booster engine, and one or more thrusters adapted to be connected to the projectile and capable of being spun during launch around a longitudinal axis of the projectile, the control circuitry being operatively connected to the one or more thrusters; wherein responsive to ignition of propellant stowed in a combustion chamber of the booster engine, the booster engine causes the projectile to launch from its cell; following launch of the projectile, the control circuitry is configured to activate one or more thrusters that cause the projectile to turn at a certain rate and a certain azimuth.

Spinning Projectile
A projectile fired from a weapon which has a bore with inner rifling, having a point and a base which are disposed within a sleeve such that the point and base of the projectile rotate independently of the sleeve when fired from a gun or similar weapon designed to discharge projectiles or similar material.

Hybrid annular-cantilevered snap-fit joint
A safe and reliable multi-component projectile enables cost effective manufacturing and assembly of the projectile. Major components of the projectile are joined by a plurality of shear pins interfacing with scalloped geometry of the components. The components are then held together by forcibly joining them using a hybrid annular-cantilevered snap fit joint. The tooth and groove arrangement exists where the teeth are at the end of a spring-leaf like feature of one of the mating parts and the groove is located on the opposite mating part.

High spin projectile apparatus for smooth bore barrels
A projectile apparatus is provided that includes a projectile, a propellant, and optional components such as a wading, a sabot, and an intermediary device. The projectile can be fired through a barrel having a smooth bore. A sabot is provided that can include molded features, for example, a base portion and a plurality of petal portions defining, in-part, a volume for accommodating a projectile. The sabot and wadding can include molded features that control and direct gases produced by the propellant. The apparatus can convert gas pressure or gas velocity into a high rate of projectile spin. The projectile has long-range accuracy due to a high or sustainable velocity and high rate of spin.
