Propellant Improvement Program. Volume 2. Iron Contamination Effect in HDA (High Density Acid)

Abstract

The report concerns research on improving the liquid propellant system of unsymmetrical dimethyl hydrazine and fuming nitric acid (also designated as High Density Acid). The studied and presented objectives are the forced convection heat transfer characteristics of Standard and Modified high Density Acid (HDA) and the effect of iron impurity level up to 100 parts per million as Fe2O3 on HDA heat transfer. Thirty tests were conducted using resistance heated, circular, 6061T6 aluminum tubes. Results showed that normal nucleate boiling did not occur with either of the HDA compositions. The experimental forced convection heat transfer coefficients were unaffected by iron impurity level and exhibited increased values with increased bulk temperature.
