US 8,985,002 B2 · Air blast wave protection

Abstract

A method of designing a wearable air blast wave energy protection device includes computer modeling at least two candidate reflective materials for a first human-protective and primarily reflective response to a specified incident air blast wave energy. The method includes selecting a layer of a first material from the at least two candidate reflective materials based at least partially on the computer modeling of the at least two candidate reflective materials. The method includes computer modeling at least two candidate attenuative materials for a second human-protective and primarily attenuative response to the specified incident air blast wave energy transmitted through the selected layer of the first material. The method includes selecting a layer of a second material from at least two candidate attenuative materials and electronically maintaining informational data corresponding to the selected layer of the first material and the selected layer of the second material.
