High Pressure Breathing System

GTL proposes to develop a small diameter High Pressure Breathing Apparatus concept design capable of achieving 10,000-psi operating pressures. The HPBA incorporates a high-pressure regulator and valve that makes it compatible and component replaceable with existing conventional SCUBA and SCBA equipment. The HPBA tank incorporates several GTL innovations integrated into an optimized solution including graphite composite structures with integration of GTL"s BHL technology that provides high-pressure oxygen compatibility and gas permeable resistance. An innovative high-pressure regulator/valve system has been proposed that combines an integrated design concept leveraging innovative valve and regulator technologies. The proposed phase 1 effort develops concept designs that leverage mechanism technologies and integrated composite structures and pressure vessel technologies being developed at GTL. An integrated design approach is expected to provide a 90% reduction in weight and an 80% reduction in size compared to a standard 3,000 psi 7.25 inch diameter and 26-inch long aluminum tank.
