A method of controlling a gyroscopically-stabilized projectile, comprising a control system producing a control signal, a rotating aerodynamic shell, and a reaction mass system responsive to the control signal, the method comprising: imparting rotational and translational kinetic energy to induce gyroscopic stabilization of the projectile about a gyroscopic axis and a movement of the projectile along a flight path; interacting the shell with surrounding air while moving, to induce aerodynamic forces; generating the control signal from the control system; and altering a state of the reaction wheel system selectively in dependence on the control signal, to alter the flight path.

An aeromechanically stable sabot system that includes a center of gravity that is placed forward of an aerodynamic center of the aeromechanically stable sabot system when in steady-state flight. By placing the center of gravity forwards of the aerodynamic center, the sabot system exhibits positive longitudinal and directional stability. To illustrate, the sabot system and/or portions thereof will return to stable flight after being disturbed in pitch (vertically or about a transverse horizontal axis) or yaw (side to side or about a vertical axis) when traveling horizontally.

Missile balancing assemblies include two balancing rings configured for mounting on a missile, each balancing ring having a ballast. Each balancing ring is configured to be rotated and rotationally fixed, and may include materials having different densities at different locations. Each balancing ring may further include an angular graduation.

A guided projectile including a precision guidance munition assembly utilizes angular rate sensors to sample a first angular velocity of the precision guidance munition assembly from the first angular rate sensor at a first time, sample a second angular velocity of the precision guidance munition assembly from the second angular rate sensor at the first time, generate a coning command based, at least in part, on the first angular velocity and the second angular velocity, and apply the coning command to the canard assembly. The range may be decreased or increased based on the coning commands.

A color marker projectile, which is intended as a non-lethal projectile to mark a hit with color, is located in the projectile itself and is poured over the target on impact. The projectile is launched from a conversion kit (new barrel and bolt) of a real weapon. The color marker projectile includes a front part, a rear part, an inserted element and a color filler. The front part is formed as a semicircular cylindrical part with vertical ribs. The inserted element is positioned to complete the concluded cylindrical part of the front part. The color filler and the inserted element are positioned on the inside of the front part. The color filler is located at the contact point between the front part and the rear part.

A rear slip base plate for a round carrying a guidance and control unit payload, which round is launched from a rifled launch tube. To prevent the guidance and control unit payload from also being rapidly spun with the round, the slip base plate unit mechanically isolates the guidance and control unit payload from the round spin rate.

An assembly and method for assembling a projectile with a compact low friction high temperature shaft seal is provided. The assembly includes an outer shell, a rotating shaft inside the outer shell, and a seal attached to the rotating shaft. The rotating shaft can rotate independently of the outer shell. The seal can seal a gap between the outer shell and the rotating shaft.
