The work covered by this report represents two separate areas of endeavor. One part is concerned with the study of the suppression of cryogenic propellant explosions and the other with the determination of the flammability characteristics of selected halogenated hydrocarbons. The work on cryogenic propellant explosions includes a study of the liquid H-solid O and liquid O-RP 1 systems. A study of suppression of gas-phase detonations is also included. The initiation sensitivity of the liquid H-solid O combination was determined by a projectile impact test. Results for the system containing liquid H-solid O-solid N are also described. These indicate that desensitization of the condensed-phase H-O system is possible. Studies indicated that powders do not exhibit suppressant effects comparable to those exhibited by gases and vapors. Autoignition temperatures are being determined for each of four halogenated hydrocarbons. Author
