Abstract:
1. A device for simulating an explosive blast shock wave, comprising: a source of compressed gas; a primary conduit conveying gas from the source of compressed gas along a primary axis of gas flow, wherein the primary conduit comprises a release valve that opens when gas pressure at the release valve reaches a predetermined pressure; a secondary conduit extending at an angle to the primary conduit axis of gas flow, wherein the secondary conduit terminates in an outlet orifice that directs gas from the primary conduit toward a target region, and the secondary conduit exits the primary conduit between the source of compressed gas and the release valve; a trigger releasing the compressed gas into the primary conduit toward the release valve to generate a simulated blast shock wave flow of gas through the outlet orifice, wherein a pressure amplitude of the blast shock wave increases until the release valve in the primary conduit opens and reduces pressure in the secondary conduit and at the outlet orifice; a specimen platform positioned adjacent the outlet orifice.
