This investigation was conducted to determine the effect on performance and temperatures of the addition of either liquid hydrogen or liquid ammonia to three bipropellant systems of current interest. These bipropellant systems are nitrogen tetroxide-hydrazine, hydrogen peroxide-hydrazine, and RFNA-hiydrazine. For each tripropellant system all important parameters and chamber and exhaust temperatures are determined for equilibrium flow conditions and constant composition flow conditions. All the results are listed in tables and the effects on several of the more important parameters are illustrated graphically. The results show that theoretically the effect of the addition of the third component is desirable by causing reduction in temperature and increase in performance. New parameters are introduced for utilization in predicting performances of tripropellant systems once the chamber temperature has been calculated or estimated.
