High Pressure Diver Breathing Gas Supply System

ADA Technologies proposes to advance the development and certification of a novel ultra-high-pressure scuba capable of supplying Navy divers with vastly increased breathing air capacity without volume or weight penalty to allow longer submersion time. The system employs one or more composite cylinders and an innovative first-stage regulator coupled with commercial-off-the-shelf scuba parts. With this additional submersion time, divers will have increased operational flexibility resulting in a higher likelihood of mission success. In Phase I, a first prototype regulator was designed, built and tested at up to 10,000 psi. It was interfaced with COTS second-stage components to demonstrate preliminary full system functionality. In Phase II, a rigorous, stage-gated product development process will be followed to reach TRL 7 and initiate certification tests of the new ultra-high-pressure scuba. The plan includes a Preliminary Design Review (PDR) and a Critical Design Review (CDR) to document the progress of the system design. A Phase II Option plan is proposed as well, as an additional third year will likely be needed to complete the certification tests required for military use. Established diving equipment partners have expressed interest in collaborating with ADA Technologies to commercialize the technology in multiple markets.
