Abstract:
1. An assembly for protecting an object from an explosion, comprising: (a) at least one aerogel layer arranged to substantially intercept shock waves and gas at pressure exceeding ambient before impinging upon the object, (b) at least one space between said aerogel layer and the object to be protected from the explosion, said at least one space being at least (c) at least one component that defines said space and substantially resists deformation of the space prior to impingement from the explosion, (d) at least one frangible element separating said aerogel layer from the space; and (e) said at least one space is substantially created by at least one channel affixed to the frangible element and arranged such that the gas from the explosion transmitting through the aerogel layer and fragments from the frangible element can enter said space created by said channel, said channel comprising sides and a base connecting said, sides, the base of the channel being arranged furthest from a direction of an anticipated approach of the gaseous products generated by the explosion and toward the object being protected from the explosion.
