Bomb blanket

Abstract

Abstract A bomb blanket adapted to be placed over a bomb about to explode so as to minimize the lateral blast effect and to contain the spread of shrapnel, said blanket including upper and lower covers fabricated from moisture-resistant and fire-retarding material, a plurality of layers of ballistic cloth located between the covers to make the blanket shrapnel proof, and a plurality of centrally located apertures extending through the ballistic cloth with the size, number, and orientation of the apertures being parameters selected to permit the gas released by an explosion to vent therethrough and create a vacuum under the central portion of the blanket. The effectiveness of the blanket is due to the downward flexure or puckering of the corners of the blanket about the bomb as the bomb explodes so as to reduce the lateral blast effect and to prevent spread of shrapnel, such puckering being primarily attributable to the partial vacuum or venturi effect created on the underside of the blanket in the central region thereof as the gas released by an explosion vents through the apertures. The effect is enhanced by limiting the number of layers of ballistic cloth which extend the full dimension of the blanket so as to allow the corners of the blanket to more readily flex downwardly to enclose about the bomb. The effect is still further enhanced by tightening an adjustable strap arrangement to initially set the blanket in a puckered state about the bomb prior to explosion.
