Abstract:
Combustibility studies of materials of construction employed in space flight vehicle cabins have been carried out as a function of various simulated cabin atmospheric environments. The program was conducted under three distinct phases. Phase 1 efforts were directed at defining the spontaneous ignition temperature, of the individual materials, under dynamic atmospheric conditions for the various atmospheres employed. Phase 2 centered about the burning characteristics of the respective materials as a function of atmospheric and gravitational environments. These studies also involve the effects of various extinguishants upon the burning characteristics under the influence of several atmospheric environments and gravitational variations. Phase 3 focused upon the flame spread behavior of the material, under the influence of various atmospheric environments and in the presence of Halon 1301 flame extinguishant. Detailed analyses of the work clearly show the dependency of the combustion behavior of the materials upon the atmospheric environment utilized.
