An experimental investigation was performed on the use of Hybaline A14 as a combustion instability suppressant in a LO2RP-1 combustion system. A pulse motor combustion stability evaluation tool was used for the test program. Tests were conducted with three different concentrations of Hybaline A14 i RP-1. These concentrations were, by weight, 6.6, 10.9, and 15.5. Tests were also conducted using RP-1 without additive which provided baseline data for comparative evaluation. A total of eighteen tests were conducted over a prescribed mixture ratio range of 2.0 to 3.0 and at two different chamber pressure levels, 300 and 500 psia. A pulse gun stability rating device was used to artificially perturb the combustion process. Relative stability characteristics were compared by considering the combustion system response to induced pressure disturbances, size of disturbance required for instability, damping characteristics and resultant instability modes and oscillation amplitudes.
