Abstract
Shock-tube techniques have been used to determine rates of carbon dioxide production in shock-wave heated mixtures of oxygen and hydrogenated dimers of bicycloheptadiene, components of the high density fuel RJ-S. Reaction profiles generated by this method have demonstrated that the combustion rate of the hydrocarbon vapors increases with fuel and oxygen concentration, but is not affected by the total pressure over the temperature (1900-3600°K) and pressure (1-1.5 atm) range investigated. An activation energy of combustion was determined to be 18±2 kcal/mole from the variation of combustion rate with temperature. An investigation of the individual components of RJ-5 revealed that their combustion does not differ significantly from that of RJ-5.
