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.
Abstract (de)
Bei einer Zünderauslöseeinrichtung am Kopf (1) eines Unterwassergeschosses ist ein Druckaufnehmer dem Staudruck ausgesetzt. Die Zünderauslöseeinrichtung soll es erlauben, verschiedene Staudruckänderungen auszuwerten, und ohne bewegliche Teile arbeiten. Es ist hierfür im Kopf (1) des Geschosses eine mit elektrischen Kontakten (7, 9) versehene Piezokeramikscheibe (8) an ihrer einen Seite starr gestützt. An ihrer anderen Seite liegt ein Druckübertragungskörper (11) an.
