Feasibility Study of 2000 Foot Underwater Breathing Apparatus

摘要

In this research program the feasibility of developing an underwater breathing apparatus (UBA) for use at depths in the 2000 foot range was studied. It was found that every presently known system has inadequacies that would preclude its efficient use at such depth, but that combining some of the features of the present UBA's could result in a useful apparatus. It was found that a backpack mounted scrubber, with integral gas heating and P02 control, with a fan-driven circulation system, could be interfaced with the present Mark 12 diving apparatus to produce a UBA that would satisfy the operational requirements.
