Abstract: 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.

Abstract: A fin deployment mechanism for a projectile to release the fins laterally or radially. This pop-out type of mechanism therefore avoids need for a sabot for projectile launching purposes. By avoiding the weight and space usage of a sabot, there can be increased length and volume for the warhead and projectile, at the same weight burden.

Abstract: The present invention is directed to a bendable projectile having a forebody unit, a rearbody unit and an articulating joint unit connecting the two units. The articulating joint unit is composed of a spherical shape body, a receiving socket and a sphere-gear assembly. The spherical shape body is fitted into the receiving socket whereby movement of the spherical shape body about the receiving socket is permitted without release of the spherical shape body from the socket. Movement of the spherical shape body inside the receiving socket is effectuated by the sphere gear assembly. The sphere-gear assembly engages the concentric grooves along the surface of the spherical shape body or the concave surface of the receiving socket. Such sphere-gear assembly is comprised of electric board, powersource, powertrain, guidance control system and gears having teeth and grooves that complement the plurality of concentric grooves on the spherical shape body.

Abstract: A non-lethal cargo projectile comprises a projectile body; a fuze adapter attached to a front of the projectile body; a fuze attached to the fuze adapter; a boattail attached to a rear of the projectile body; a pressure tube extending from the fuze adapter to the boattail; a decelerator and drogue chute disposed aft of the fuze adapter; a flexible line that connects the pressure tube to the decelerator; a center disc disposed aft of the decelerator and drogue chute; a rear disc disposed aft of the center disc, the center disc and the rear disc defining a payload volume therebetween; a second flexible line that connects the rear disc to the boattail; at least one shearable fastener that fastens the projectile body to the fuze adapter; and at least one vent extending from the boattail to the fuze adapter.

Abstract: A practice projectile allows for the release of flame or smoke and bang upon impact to simulate a successful deployment of the tactical cartridge. The practice projectile includes three main components: a center vent tube, a plurality of vent holes, and a plurality of vent plugs. The center vent tube compensates for the physical properties of the tactical mortar cartridge and provides a passage for an efficient release of smoke upon a fuze function. The vent holes are positioned at the rear end of the projectile body to sufficiently release pressure, flame and smoke upon a fuze function. The vent plugs seal the vent holes to protect the interior of the projectile during storage, handling, and launching.

Abstract: A non-lethal cargo projectile includes a projectile body; a nose cap attached to a front of the projectile body; a boattail attached to a rear of the projectile body; a fin assembly including a boom attached to the boattail; a parachute assembly disposed in a front of the projectile body; a cable connecting the parachute assembly to the boattail; a fuze disposed in the boattail; a first pair of half cylinders disposed in the projectile body behind the parachute assembly; a first circular disc disposed at a front end of the first pair of half cylinders and a second circular disc disposed at a rear end of the first pair of half cylinders; a second pair of half cylinders disposed in the projectile body in front of the first circular disc enclose the parachute assembly; and a payload disposed in a space defined by the first pair of half cylinders and the first and second circular discs.

Abstract: Obturator ring comprising two or more pieces each being a little larger than semicircle of the projectile obturator ring groove circumference. Each piece at natural position has equal or smaller radius than the radius of the obturator ring groove of a projectile; therefore, each piece expands to be in the projectile groove. Thickness and height of each piece is dependent on projectile's obturator ring groove geometry. The overlap and the radius ensures each piece performs its own grip function independent to the completion of the Segmented Obturator Ring (SOR). SOR seals the expanding propellant gases in the tube optimizing the effectiveness of the propellant while the projectile moves along the gun tube with SOR. After launch, the SOR is totally separated from the projectile minimizing drag effects on and maximizing stability of projectile to enhance dispersion impacts of the warhead.
