Abstract: A linear actuation system includes a pin pivotably coupled to an output rod of a linear motion actuator and a rotatable output shaft that includes a bushing therein. The pin can be configured to slide in and out of the bushing in response to movement of the linear motion actuator. The linear motion actuator and the output shaft can be arranged such that travel of the pin in the bushing causes rotation of the output shaft.

Abstract: A system for restraining one or more control surfaces of a tactical flight vehicle includes a retaining frame secured at an aft end of the tactical flight vehicle and a cover plate releasably coupled to the retaining frame with a resilient lock ring. The resilient lock ring is disposed between the retaining frame and the cover plate and is deformable between a locking configuration and an unlocking configuration. A control surface restraining ring is releasably coupled to the cover plate and has control surface restraints configured to engage respective control surfaces. The resilient lock ring is configured to deform from the locking configuration to the unlocking configuration upon a launch of the tactical flight vehicle such that the cover plate becomes uncoupled from the retaining frame and may be jettisoned from the tactical flight vehicle after the launch.

Abstract: A guided projectile having a nose portion, a body portion, a tail portion, and a central axis. In various embodiments the projectile includes a control support portion and a collar assembly pivotally mounted to the control support portion. In various embodiments the collar assembly includes a collar having an exterior sidewall with a plurality of fixed aerodynamic surfaces thereon for spinning the collar and a plurality of variable sweep wings for directional control of the projectile. In various embodiments the plurality of variable sweep wings each have a first end coupled to a wing actuator configured to rotate a second end portion between and including a first position, where the wings are oriented generally parallel to the central axis of the projectile to a second position, where the lengthwise wing axis of the plurality of wings are oriented generally perpendicular to the central axis of the projectile.

Abstract: A drive mechanism for actuating a control surface of a vehicle that moves through a fluid medium. The mechanism directly translates the rotational motion provided by an input drive to a control surface that is used to direct the vehicle. The mechanism provides both weight and space savings as well as limits, if not eliminates, backlash. The angled drive mechanism may be particularly suited for use in applications such as UAV/UUV, munitions, and other relatively small platforms.

Abstract: 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.

Abstract: A guided missile with a sleeve-shaped missile body, at least one engine for producing forward thrust, at least one flight direction control device, and at least one aerodynamic extension. The least one flight direction control device is rotatably mounted to a top area and/or a bottom area of the sleeve-shaped missile body for adjusting a flight direction of the guided missile. The least one aerodynamic extension comprises an aerodynamic cross-sectional shape that is arranged on a left-hand side and/or a right-hand side of the sleeve-shaped missile body.

Abstract: A device for blocking a fin of a projectile, the fin including a fin base pivoting about a pivot pin secured to the body of the projectile between a withdrawn fin position and a deployed fin position, wherein the device includes at least one recess housing at least one shape of revolution pushed by a resilient means between a first surface borne by the fin and a second surface borne by the body of the projectile, at least one of the two surfaces forming a ramp that converges toward the other surface to tend to cause jamming of the shape of revolution between the two surfaces.

Abstract: A flap actuator for adjusting the orientation of a flap or the like, the actuator. The actuator includes: a static arcuate member having a radius of curvature; a piezoelectric motor biased to be in operable contact with the static arcuate member; a housing for housing the piezoelectric motor; and a flap orientation shaft operably connecting between the housing and the flap. The distance between the shaft and the static arcuate member is essentially equal to the radius of curvature of the static arcuate member.

Abstract: A munition including: a control surface actuation device including: an actuator having two or more pistons, each of the pistons being movable between an extended and retracted position, the retracted position resulting from an activation of each of the two or more pistons; and a movable rack having a pocket corresponding to each of the two or more pistons, each pocket being engageable with a corresponding portion of each of the two or more pistons, a distance between the pockets being different than a distance between the portions of the two or more pistons, such that activation of the portion into the corresponding pocket sequentially translates the rack; and a control surface operatively connected to the rack such that translation of the rack rotates the control surface.

Abstract: Techniques and architecture are disclosed for a system that includes a fuze at a leading end of a projectile body and a fuze setter configured to engage the fuze and to program the same prior to launch. The system, in one example, includes a plurality of electrical contact pads on an exterior surface of a fuze radome housing and a plurality of electrical contact pins on the fuze setter. The electrical contact pads are arranged in a rotationally symmetric pattern that enables an electrical interface to be formed with the electrical contact pins, regardless of the rotational orientation of the fuze. Commutation is performed to rotate signals to the electrical contact pins instead of requiring that the fuze be physically rotated to bring the electrical contact pads into alignment with the electrical contact pins.
