Abstract: A detonation wave barrier for disposition between adjacent segments of warhead explosive including first and second layers of high shock impedance material and a third layer of low shock impedance material between the first and second layers.

Abstract: A fragment warhead including an explosive divided into a plurality of axially adjacent segments by detonation wave barriers. At least one detonator is embedded in each segment. A fragmentation layer encases the explosive, and a fuze selectively activates at least one detonator in each segment to generate a fragment pattern having selected width and angular direction.

Abstract: In order to evaluate competing explosive trains at explosive interfaces, at least one penalty barrier is inserted in the gap between a donor explosive component and an acceptor explosive component. Each of the barriers, if more than one, has a first layer and a second layer. The first layer is selected to have a shock impedance greater than the second layer so that a shock pulse is attenuated to a desired degree. Additional barriers can be added to increase the attenuation. A use of this device allows the shock intensities to be varied without varying wave shape or duration and further allows use of established shock equation of states of materials.

Abstract: An optical impact fuze employing a transparent nose of a target seeking missile as a light transmission medium which deforms upon impact to reduce optical transmission and initiate a fuzing signal. Alternatively, one or more optically transmissive filaments can be positioned at or near a predetermined target impact point on a vehicle so that a fuzing signal is initiated upon the detection of an abrupt decrease in light transmitted by the filament resulting from target contact.
