Abstract (en)
[origin: US4648320A] A detonator triggering device which is located in the head of an underwater projectile, and wherein a pressure receiver which is positioned within an opening in the projectile head is exposed to a dynamic pressure or velocity head. A piezo-ceramic disc which is equipped with electrical contacts is rigidly supported on one side thereof in the head of the projectile, and with its other side contacts against a pressure transmitting member which is supported within the opening in the head. As a result, the dynamic pressure will act against the piezo-ceramic disc. Every change in the dynamic pressure consequently provides for a corresponding change in the charge or change in the voltage of the piezo-ceramic disc. This permits itself to be processed in an electronic evaluating or gating circuit, such that the applicable voltage change is employed as the actuating criteria.
