Estimating the term…
A miniaturized delay element was developed for use in medium-and large caliber weapon systems and is realized in a metallic cartridge made of a copper-free light metal. By including a metallic combustible, an oxidant consisting of a halogen-containing high polymer, and metallocenes as sensitizers, an extremely compact and reliable delay element can be produced. By including a detonating charge consisting of an initiating explosive and a metallocene as sensitizer, the delay element can be designed for initiation without darting flame, for striker pins, needles, etc. Due to its properties, the pyrotechnical delay element is particularly well suited for use in highly delayed charges and/or for daughter projectiles and/or for self-destruction of munitions. The delay times achieved can be experimentally and reproducibly determined between 1 and about 30 sec.
A pyrotechnical delay element comprising at least a booster charge consisting of a combustible and an oxygen carrier, a delay charge consisting of a combustible, an oxygen carrier, a binder, a sensitizer and an inert additive, as well as of a primer charge for the main charge, said charges being arranged one after the other in a cartridge, characterized in that said cartridge is made of a metallic material of high thermal and chemical resistance, and that said delay charge consists of a mixture of a metallic combustible, a halogen-containing, polymerized oxidant and a metallocene as sensitizer.
