ABSTRACT:
A blast reducing structure having a first web and a second web. Each of the webs having a first section defining a first plane, a second section defining a second plane, the second plane being generally parallel to the first plane, an interconnecting section interconnecting the first section to the second section. The first web is disposed in mirrored relationship to the second web to define a volume. An energy absorbing liquid is disposed in the volume, such that the first section, the second section, and the interconnecting section cooperate to collapse in response to an impact pulse, thereby dissipating force associated with the impact pulse. Alternate volumes may be air-filled so as to accept the expelled liquid.
