Title

(EN) SYSTEMS AND METHODS OF SURFACE-ENGINEERED ENERGETIC COMPOSITES FOR HEATING AND COMBUSTION IN UNDERWATER AND LIQUID ENVIRONMENTS

(FR) SYSTÈMES ET PROCÉDÉS DE COMPOSITES ÉNERGÉTIQUES MODIFIÉS EN SURFACE POUR LE CHAUFFAGE ET LA COMBUSTION DANS DES ENVIRONNEMENTS SOUS-MARINS ET LIQUIDES

Abstract

(EN) Provided are systems and method for surface-engineered energetic composites for combustion in underwater or other liquid environments. A method of preparing a surface-engineered energetic composite includes combining a metal fuel and an oxidizer to achieve a metal-oxidizer composite, and coating the metal-oxidizer composite with a surface-engineered layer to generate a surface- engineered metal-oxidizer composite. A energetic composite system includes an energetic composite comprising a fuel component and an oxidizer component, a surface-engineered layer on at least a portion of the energetic composite, and an ignition source; wherein upon heating to a first threshold temperature by the ignition source, the surface-engineered layer decomposes to generate a localized insulating vapor region, and upon heating to a second threshold temperature, the fuel and oxidizer components exothermically react within the insulating vapor region.

(FR) L'invention concerne des systèmes et un procédé pour des composites énergétiques modifiés en surface pour la combustion dans des environnements sous-marins ou autres environnements liquides. Un procédé de préparation d'un composite énergétique modifié en surface comprend la combinaison d'un combustible métallique et d'un oxydant pour obtenir un composite métal-oxydant, et le revêtement du composite métal-oxydant par une couche modifiée en surface pour générer un composite métal-oxydant modifié en surface. Un système composite énergétique comprend un composite énergétique comprenant un composant combustible et un composant oxydant, une couche modifiée en surface sur au moins une partie du composite énergétique, et une source d'allumage ; lors du chauffage à une première température seuil par la source d'allumage, la couche modifiée en surface se décompose pour générer une région de vapeur isolante localisée, et lors du chauffage à une seconde température seuil, les composants combustible et oxydant réagissent de manière exothermique dans la région de vapeur isolante.
