Experimental Study of Combustion Stability of Tripropellant

摘要

OTTO/HAP/seawater tripropellant experimental system applied to underwater thermal power was designed and its combustion stability was experimentally investigated under various combustor pressures, component ratios, injector pressure and combustor rotate speed. In the experiments, low frequency combustion instable oscillation was found. The experiments results show that higher injector pressure and lower HAP ratio were in favor of combustion stability. Increasing the weight proportion of seawater above 42% can lead the instable oscillation of combustor pressure, but precision proportion control is favorable, and combustor rotate speed has little effect on combustion stability.
