Abstract
Methods and apparatus are provided for a blast attenuator having a container with an outer wall that defines a cavity in which a particulate media is disposed, and a stirring element disposed in and moveable relative to the container. At least a portion of the stirring element extends into the particulate media, wherein, in use, the particulate media provides resistance against movement of the stirring element relative to particulate media so as to attenuate the energy of a blast.
