Experimental results from CEM-UTS single shot 9 mj railgun
- Texas Univ., Austin, TX (United States). Center for Electromechanics
The Center for Electromechanics at the University of Texas at Austin (CEM-UT) has designed and fabricated a 10-m long 90 mm bore railgun. During the test program, a number of solid armatures and projectile packages have been tested in a 50 m deep vertical test range. The experiments are powered by six homopolar generator (HPG) charged inductive stores, sequentially staged to provide the desired acceleration profile. Prior to testing, computer simulations are run to determine the preferred current profile and predict system performance. During projectile flight, high speed films, x-rays, muzzle volts, and velocity/acceleration profiles are recorded along with power supply operating parameters. Postshot diagnostics include bore wear analysis and armature and target recovery. Comparisons of predicted and recorded shot performance are also made. On selected tests, an energy balance is performed to determine efficiencies of the various system components. In this paper, a summary of all 90 mm gun shots is presented along with critical data collected from selected tests.
