Abstract
Life support systems include a pressure garment, a helmet, and a life support system enclosure that define an enclosed environment. The life support system includes one or more life support components to generate breathable gas within the enclosed environment. The gas is directed along a closed-loop flow path through the system. The life support components includes a fan for driving a flow of the gas through the closed-loop flow path and an acoustic damper arranged along the flow path and to reduce noise generated by the fan. The acoustic damper includes a housing defining an annular cavity arranged about a portion of the flow path, with the housing having a solid exterior surface and an inner diameter surface with openings to fluidly connect the flow path with the annular cavity and at least one acoustic damping element arranged within the annular cavity.
