SPACE VEHICLE PROPULSION COMPARTMENT FIRE HAZARD INVESTIGATION, VOLUME 1,

Abstract

The report presents the results of the space fire hazard investigation program. The purpose of the program was to determine if a hazardous condition existed under vacuum conditions with regard to leakage of rocket propellants in space vehicle propulsion compartment areas. Tests were conducted under various potentially hazardous conditions at altitudes from 25,000 to 200,000 feet. No attempt was made to define ignition characteristics of the combustible combinations investigated. The test specimens were N2O4, N2H4 and 50% unsymmetrical dimethylhydrazine and 50% hydrazine (0.5 UDMH-0.5 N2H4). Other combustibles i.e., hydraulic fluid, lubricating oil and grease were tested in combinations with a fuel and oxidizer. Non-metallic materials were also tested in combination with the oxidizer and fuels. Analysis of the data revealed that propellant leakage within closed compartment areas can result in fires and explosions. (Author)
