Title (EN) SOLID PROPELLANT WITH INTEGRAL ELECTRODES, AND METHOD OF ADDITIVE MANUFACTURING
(FR) PROPULSEUR SOLIDE AVEC ÉLECTRODES INTÉGRÉES, ET PROCÉDÉ DE FABRICATION ADDITIVE
Abstract:
(EN) A device may include an electrically-operated propellant or energetic gas-generating material, additively manufactured together with electrodes for producing a reaction in the material. The device may also include a casing that is additively manufactured with the other components. The additive manufacturing may be accomplished by extruding or otherwise depositing raw materials for the different components where desired. The electrodes may be made of a conductive polymer material, for example using an electrically-conductive fill in a polymer.
(FR) La présente invention concerne un dispositif qui peut comprendre un propulseur à commande électrique ou un matériau générateur de gaz énergétique, fabriqué de façon additive conjointement avec des électrodes pour produire une réaction dans le matériau. Le dispositif peut comprendre en outre un boîtier qui est fabriqué de façon additive avec les autres composants. La fabrication additive peut être effectuée par extrusion ou dépôt selon une autre méthode de matières premières pour les différents composants de façon souhaitée. Les électrodes peuvent être constituées d’un matériau polymère conducteur, par exemple au moyen d’une charge électriquement conductrice dans un polymère.
