    摘要： The present invention describes an electronic fuze operable to complement a mechanical point impact fuze. The electronic fuze includes a voltage generator circuit, micro-controller, a piezo-electric sensor, a firing circuit and a safety lockout circuit. When a projectile strikes a target at an optimum angle, the mechanical point impact fuze is activated; when the strike angle is oblique, the mechanical point impact fuze may be ineffective but the piezo-electric sensor is operable to trigger the firing circuit. The safety lockout circuit ensures the firing circuit is operative only after a predetermined delay time when an n-channel FET is turned OFF. The micro-controller also generates a TIME-OUT signal, which provides for self-destruction of a projectile that has failed to explode.

    摘要： An elongated, aerodynamically improved ballistic projectile fuse, having an overall fuse length greater than its maximum diameter by a factor of approximately two, includes a lightweight aluminum fuse body having forward and rearward portions and an interiorily disposed firing pin with a shearable flange thereon. A steel sleeve mounted in the fuse body is provided for supporting the firing pin with a head portion thereof forwardly directed and exterior to the sleeve and for guiding the firing pin through the fuse body toward the rearward portion thereof subsequent to impact of the fuse with a target. A cap, enclosing the firing pin head, is configured for collapsing and impacting the head upon fuse impact with a target, thereby causing shearing of the firing pin flange and driving of the firing pin rearwardly toward detonation means disposed within the fuse body rearward portion. The cap is in turn enclosed by a windscreen which provides an aerodynamically streamlined, forward continuation of the fuse body. Means joining the windscreen to the sleeve enables separation therebetween on target impact, thereby enabling the windscreen to collapse the cap.

    摘要： A projectile fuze in which premature detonation is minimized, particularly during projectile flight through rain or heavy tropical storms. The projectile fuze nose portion has a shock absorbing end closure mounting the firing pin and its actuating impact responsive member which withstands raindrop impacts prior to target engagement. The end enclosure has preweakened members that facilitate deforming and dislodging of the closure on target impact to enable firing pin actuation.
