Development of a mobile gas gun
Sandia National Laboratories Division 9122 is completing construction of a portable, 6'' bore, high performance, single stage compressed gas (air/helium) gun. The gun was developed to accommodate direct penetration tests into geologic media at a variety of impact and incidence angles freeing users of reverse ballistic and/or target simulation methods. It is designed to propel projectiles (5 lbs.) up to 2500 ft/sec. Initial operation and performance evaluation began in August 1988. The gun will be fully operational in October 1988. The gas gun is mounted on a 50' by 8' trailer. In addition, all ancillary equipment, compressor, electrical generator, two 25 cubic foot storage tanks and one 7 cubic foot power chamber tank, valves, and pressure control are mounted on the trailer. The trailer is tethered to an IBM PC with a 4 conductor cable to accommodate remote firing. Several test series have already been scheduled for this gun in FY89. These include a lateral loading benchmarking study with 10 lb. projectiles instrumented with 6 channels of acceleration and strain data, a controlled depth of burial study for 40 lb. runway penetrators, and a scale model study of multilayered target penetration. The last two series are being done under the Joint DOD/DOE Munitions Technology Development Program. In this paper we will discuss the design, development and operational capability of this new mobile gas gun. 2 refs., 3 figs.
