Abstract:
1. A blast reducing structure comprising: a first web and a second web, each of said webs having a first section defining a first plane, a second section defining a second plane, said second plane being generally parallel to said first plane, an interconnecting section interconnecting said first section to said second section, said first web being disposed in mirrored relationship to said second web to define a volume; an energy absorbing liquid being disposed in said volume; and an aperture formed in at least one of said first section, said second section, and said interconnecting section and in fluid communication with said volume permitting said energy absorbing liquid to pass therethrough in response to an impact in a direction orthogonal to a direction of said impact, wherein said first section, said second section, and said interconnecting section cooperating to collapse in response to the impact, thereby dissipating force associated with the impact, said energy absorbing liquid further frictionally and viscously dissipating said force associated with the impact.
