Abstract
Eine platzsparende Sicherungseinrichtung (1) sieht für eine Drallge schoßzünder einen radial aufweitbaren Haltering (2) vor, der in Sicherstellung des Rotors (5) diesen innerhalb eines Zündergehäuses (7) zentriert. Der Haltering (2) wird in axialer Richtung über einen konischen Zentrierdorn (3) auf dem Rotor (5) gehalten. Bei vorge sehener Abschußbeschleunigung und Drall wird aufgrund der Massenkräfte der Haltering (2) axial zurückversetzt und bleibend verformt. Der Rotor (5) ist dadurch entsichert und schwenkt in eine Scharfstellung ein. A space-saving securing device (1) provides for a swirl shot detonator a radially expandable retaining ring (2) in Securing the rotor (5) within a detonator housing (7) centered. The retaining ring (2) is in the axial direction over a conical centering mandrel (3) held on the rotor (5). At pre Accelerated launch and spin is due to the mass forces the retaining ring (2) is axially set back and permanently deformed. The This unlocks the rotor (5) and pivots it into focus a.
