BYU ARG Gets Gatlinged!
Members of the BYU Acoustics Research Group, led by Dr. Kent Gee, recently measured the acoustical radiation of the 30-mm GAU-8 Avenger, the seven-barrel Gatling gun used on the A-10 Warthog (nicknamed the "tank killer"). The gun can fire 70 rounds per second and, as measured, causes compressive pressure fluctuations greater than 1 atmosphere near the gun. The measurements were sponsored by HHI corporation, a Farmington, UT-based company tasked with designing an indoor firing range for the gun at Hill Air Force Base.
