ABSTRACT:
A regenerative monopropellant inflator having improved initiation of the regenerative cycle and improve operating efficiency. The inflator may direct the flow of the monopropellant into a localized volume to create a "hot spot" to increase combustion. This serves to ensure that the regenerative cycle is initiated. Various arrangements are provided to increase the residence time of the combusting monopropellant within the inflator, to ensure complete combustion of the monopropellant, and thus increased efficiency. These arrangements include inducing a helical gas flow to increase the length of the path traveled by the gas. Various barriers may also be placed within the gas flow to force direction changes, which reduce the velocity of the gas.
