A blast wave damper comprises a section of duct, with a multiplicity of rigid elements each extending across the duct. All the elements are parallel to each other, and they are arranged in an array consisting of a multiplicity of lines, each such line extending across the duct. The elements in one line are staggered relative to the elements in an adjacent line, and the gaps between successive elements within a line are no wider than the widths of the elements. There may be ten columns of tubular elements in a regular array. This may be combined with a louver mechanism arranged to shut if the pressure drop exceeds a threshold. |
