Efficient thermal protection for a gas generator

Abstract

Aspects of the present disclosure relate to a cool gas generator (1) comprising a housing (2) having an outlet (3) for releasing generated gas, and a porous main charge (4), contained in the housing, the charge comprising a mixture (m) that generates a target gas (G) upon thermal decomposition and that will undergo a self-sustained exothermal decomposition reaction after ignition. The generator further comprises a thermal protection layer (5) that extends between the charge and the housing, whereby the thermal protection layer comprises a composition that generates target gas upon thermal decomposition by absorption of heat from the thermal decomposition reaction of the main charge. Further aspects relate to consumables for the generator.
