Blunt Trauma Torso Rig
The Blunt Trauma Torso Rig (BTTR) was developed to mimic the human chest response under moderate to high rate impacts with small loading areas.
Blunt trauma is assessed by measuring the peak dynamic deformation with custom software and correlating this to injury risks derived from biomechanical studies. The BTTR is intended for use with soft body armor, kinetic energy less lethal weapons and other distributed impacts of moderate to high speed.
