Abstract: A grenade dispensing mechanism for non-spin or low spin dual purpose improved conventional munition launched from inside a projectile. At a pre-determined point along the trajectory, the projectile time fuze which is set at the gun functions to provide initiation output to the payload expulsion charge assembly. The payload expulsion charge assembly contains a propellant which when ignited, produces a gas pressure acting on a pusher plate which acts as a piston. The gas pressure increases with time until the forces of the gas pressure acting on the pusher plate through the grenade payload to the base/tail assembly are sufficient to shear the thread attachment of the base assembly to the projectile body section. An obturator band serves to seal the expulsion gas pressures to prevent excessive gas blow-by as the payload canister assembly travels through the rifled projectile body section.

Abstract: A fuze operates in two modes. In a primary mode, the fuze functions similarly to a conventional M223 fuze. In a secondary, self-destruct mode, a pyrotechnic delay mechanism is initiated. The slide assembly is comprised of an aerodynamic safety release, a safety pin, a rotational firing pin fitted with a resilient member such as a spring, a M55 detonator, pyrotechnic initiator, a pyrotechnic delay mix and end cap. In use, the fuze is fitted to a grenade. As the grenade is dispensed from its carrier, a grenade stabilizer starts to oscillate. The oscillation results in an arming screw and an inertial weight to back out from a slide assembly, allowing the slide assembly to move to an in-line position relative to a main M55 detonator in-line with the arming screw (firing pin). Concurrently, the aerodynamic safety release is lifted in the upward direction under the force of the airstream, releasing the safety pin.

Abstract: A secondary self-destruct fuze that functions in the event the primary fuze mode fails to function, and that meets the design requirements for a low cost, highly producible no-spin/low velocity operating environment. The fuze includes a bottom plate, two spacers, a firing pin, a striker, a rotor, a pyrotechnic mix, a rotor spring, a striker spring, a weight with a firing pin, a weight spring, a bore rider, a bore rider spring, a housing, a handling safety pin, and a ribbon retainer. In use, the handling safety pin is removed upon loading of the grenade in the main carrier. When the grenade is ejected, the expulsion event forces the ribbon retainer to be uncovered and the ribbon to unfurl, which releases the safety lock feature. The unfurling of the ribbon in the air stream stabilizes the grenade by causing an upward pull force. Simultaneously, the air stream forces the bore rider and the bore rider spring out of the fuze.

Abstract: A secondary self-destruct fuze that functions in the event the primary fuze mode fails to function, and that meets the design requirements for a low cost, highly producible no-spin/low velocity operating environment. The fuze includes an improved slide assembly comprised of an aerodynamic safety release (ASR), a safety pin, a secondary firing pin fitted with a spring, a secondary detonator which is placed in alignment with the secondary firing pin, a slide, an omni directional weight release that operates at various impact angles, and a weight release support. In use, the fuze is fitted to a munition or grenade. As the grenade is dispensed from its carrier, the oscillation of a grenade stabilizer causes an arming screw to back out from the fuze slide, allowing the slide assembly to move to an in-line position relative to the center of the fuze. Concurrently, the aerodynamic safety release is lifted in the upward direction under the force of the airstream, releasing the safety pin.

Abstract: The invention relates to a fuze for a submunition grenade which will selfstruct electrically in the event that the mechanical primary inertial functioning mode fails to operate upon striking an intended target.

Abstract: The invention discloses an improved conventional munition employing a dual omblet configuration including dual shaped charges and a design which uses a Misznay-Schardin end plate with a shaped charge. Both bomblets are separately enclosed by fragmenting warheads that are positioned in tandem. the tandem bomblet design results in a nesting arrangement of the fragmenting warhead, or sub-munition, to produce maximum packaging efficiency. A forward sub-munition of a tandem bomblet will nest within a cavity of a shaped charge of an aft sub-munition.

Abstract: In a projectile wherein a payload is to be ejected at a selected point al the trajectory of the projectile, an improvement for increasing the payload through the loading of the projectile volume encompassed by the ogive portion thereof. The projectile is provided with an expulsion charge cup disposed proximate the nose for supplying an explosively expanding gas to eject the payload carried within the center and rear portions of the projectile housing. Intermediate the expulsion cup and the primary payload and within the projectile ogive there is disposed for sliding movement a pusher assembly which in one embodiment is in the form of an open cup with the closed end opposite the expulsion charge and carrying an "O" ring between its outer surface and the inner surface of the projectile housing. In the second embodiment the cup structure is in the form of two parts.
