Twenty-four (24) man-hour test of Alvin's environmental system

Abstract

ALVIN's specifications call for a 48 man-hour environmental system capability. To check this, a 24 man-hour test was run as follows: Two successive test periods of six (6) hours each with a two (2) man crew inside the pressure hull. The break after six {6) hours was solely to change the crew. It was felt that this 24 man-hour exercise would be adequate to judge the system's 48 man-hour capability, particularly since one cannister of LiOH was used, and the submarine will normally carry two {2).
