Patent ID: 8646373

Claim:
A system for reducing the effects of a blast wave, the system comprising: armor plating having a surface configured to face a supersonic blast wave propagating toward the armor plating, the armor plating surface being openly exposed to the external environment and comprising: a first peak comprising a first side surface extending outward to a first apex; a second peak adjacent to the first peak, the second peak comprising a second side surface extending outward to a second apex; the first side surface and the second side surface combining to form a first valley between the first peak and the second peak, the first apex being disposed at a first distance above the first valley and the second apex being disposed at a second distance above the first valley, the first distance being at least five times greater than the second distance, wherein the first peak, the second peak, and the first valley are configured such that the supersonic blast wave reflects from the first side surface as a regular reflection that at least partially suppresses Mach reflection of the supersonic wave caused by the second peak and the first valley.
