- Abstract
- The problem was to demonstrate the feasibility of using high expansion foam to extinguish a model fire of dry cellular fuel inside an oxygen rich enclosure at various spacecraft operating pressures. This problem was solved by assembling a 400 cubic foot hypo/hyperbaric fire test facility in which a 12 inch by 12 inch by 2 inch high opened celled foamed polyurethane fuel specimen, or a cotton twill laboratory smock fuel specimen could be burned in air; 95 percent oxygen; 70 percent oxygen-30 percent helium; and 50 percent oxygen-50 percent nitrogen environments at 5, 10, 14.7 and 16.5 psia.
