Systems and methods for casting solid propellants include a mandrel for forming geometric features in a perforation of a propellant grain. In various embodiments, the mandrel includes a frangible portion that is removed from the propellant grain after the propellant grain has cured around the mandrel. A second portion of the mandrel may be left behind in the propellant grain. The mandrel may include a support structured disposed in the through hole of the mandrel. The support structure may include a plurality of longitudinal channels for directed exhaust gasses through the mandrel upon ignition of the propellant grain.

Systems and methods for casting propellant grain

A transducer assembly configured to convert a pyrotechnic initiation to an electrical signal may comprise a magnet, a hollow tube, and a conductive element. The hollow tube may be wrapped around the magnet in the shape of a coil. The hollow tube may be at least partially filled with a thermite. The conductive element may be coupled to an outlet of the hollow tube. The conductive element may seal the outlet of the hollow tube.

Transducer assembly for electric pulse generation

An energy conversion system may comprise a substrate including a first conductive trace and a second conductive trace electrically isolated from the first conductive trace. A housing may be coupled to the substrate. An ignition compound may be located in the housing. A solder may be thermally coupled to the ignition compound such that ignition of the ignition compound melts the solder. The housing may be configured to output the solder onto the first conductive trace and the second conductive trace.

Pyrotechnic energy conversion system for ejection assembly

An obscurant-emitting composition may comprise an oxidizer comprising a cation comprising at least one of an alkali metal or an alkaline earth metal, and an anion comprising at least one of nitrate, chlorate, bromate, iodate, perchlorate, periodate, or chlorite; a fuel; and a hydrated salt composition, wherein the obscurant-emitting composition comprises between 0.001% and 8% by weight hydrated salt composition.

Obscurant emission systems and methods

An energy conversion system may comprise a connector defining a first chamber and a second chamber. An ignition compound may be located in the first chamber. The ignition compound may comprise a material that produces a conductive combustion product. A first electrode may be coupled to the connector and located in the second chamber. A second electrode may be coupled to the connector and located in the second chamber. The second electrode may be electrically isolated from the first electrode.
