Abstract
An explosive blast shield has two connected parts, a foraminous inner shield surrounded by an impervious outer shield. The inner shield has an open lower end to absorb an explosive blast of water and gas, as from an underwater explosion. The inner shield, whose area is about 20% holes, blocks most liquid from entering the space between the two shields, but gas passes readily through the holes to equalize the pressure across the inner shield. The shield may include a chimney at the upper end for release of gas and a hold-down to prevent the shield from being blown upward.
