INVESTIGATION OF AN INSULATING MATERIAL FOR DEEP OCEAN HABITAT ENVIRONMENTS.
Abstract
For missions requiring saturation dives at depths exceeding 300 feet, a warm and comfortable environment of a 'habitat' is necessary from which divers can make many excursions of limited durations in time. Effective thermal insulation of such a habitat is necessary to reduce the heating power requirements. In the first of a series of test programs reported here, expected habitat conditions for dives at an ocean depth of 600 feet were simulated in a pressure chamber. The test program consisted of determining the effectiveness of 2-inch thick reconstituted cork board for habitat insulation in an environment of 300 psia helium at 90F and 70% relative humidity. It was found that at a compression-decompression rate of 2.5 psi per minute, the reconstituted cork board was ineffective as a thermal insulation. Based upon these results, recommendations are made to extend the investigation to include other insulating and moisture impermeable materials, and to extend the test program to include deeper diving conditions.
