Abstract : This program is concerned with determining flammability of aerosol systems. A complete review of the agent flashing problem is presented together with an analysis of the problem as a whole. A constant pressure combustion chamber and a shock tube were constructed to study aerosol flammability. Studies were conducted with QL-air aerosols, detonation product gas-air mixtures, and the three component detonation product gas-QL-air system. The data show that the system flammability is dictated by the detonation product gas-air flammability and is not significantly affected by the aerosol phase. Moderate strength shock waves will ignite the system but hot metal and glowing carbon particles will not, under the conditions tested. The QL aerosol-air mixture is easily ignited by flame but not by spark. QL aerosol-air mixtures burn with difficulty due to inhibition of the combustion by the products of combustion.
