The Feasibility of Advanced Concepts in Submarine Life Support
Abstract
A methodology is developed for the evaluation of the use of diving technology as the basis for hyperbaric submarine life support with the goal of reducing the structural weight fraction incurred with great operating depth. Atmospheric life support requirements for normobaric and hyperbaric environments are determined with emphasis on human respiration and the physiological effects of pressure. The first steps of the methodology are applied to three diving technologies in various stages of development in order to evaluate the maximum, practical depth achievable and any additional mission constraints such a life support system would place on the operation of a submarine. The diving technologies are (1) mixed gas, saturation diving, (2) liquid breathing, and (3) extracorporeal membrane oxygenation. Mixed gas saturation diving has been employed in hyperbaric chambers dives to depths in excess of 2000ft; however, vertical constraint of such a life support system as a result of decompression effects make this system unsuitable for the subject application. Both liquid breathing and extracorporeal membrane oxygenation would eliminate decompression effects; however, below 600 ft treatment for high pressure nervous system would result in a narcotic induced vertical constraint.
