Abstract:

A fuel, consisting of 19 to 21 wt. NaBH4 dissolved in N2H4, was fired with ClF3 in an uncooled engine with a nominal thrust of 150 lbf and a nominal chamber pressure of 300 psia. The normal ambient pressure was 13.2 psia. Three injectors, a like-on-like, a splash plate and a triplet, were used. N2H4 and ClF3 were fired in the same engine configurations to provide baseline data. There were no significant changes in the NaBH4-N2H4 fuel chemical composition during a 2-year storage period. The ignition and combustion of the 19 to 21 wt. NaBH4-N2H4ClF3 combination were hypergolic, smooth, reliable and stable. The peak delivered uncorrected specific impulse of the 19 to 21 wt. NaBH4-N2H4ClF3 combination ranged from 217 to 239 lbf-seclbm. The peak specific impulse was the least in the like-on-like injector and the most in the triplet injector. Air Force Rocket Propulsion Laboratory theoretical data were verified. Author
