Abstract:
Twenty-four 30-gal. batches of government-furnished hydrazine-kerosene emulsions were sampled and tested. The emulsions contained either 33 or 43 aluminum by weight. Testing included physical characteristics, flow properties, chemical analysis, and long-term storage the latter included controlled temperature and field conditions. The following conclusions were reached regarding emulsions of either aluminum content 1 the rheological properties of such fluids depend on flow conditions and pipe diameter as demonstrated by nonrepeatable shear stress during flow tests, and, later, by rising sphere rheometer measurements 2 all storage samples showed emulsion degradation after approximately 8 mo, as evidenced by bulk expansion, phase separation, and solids settling 3 gas evolution rate was average for a hydrazine-based propellant and 4 the emulsions, as received, contained no agglomerates, exhibited satisfactory resistance to settling under 30-g acceleration, and showed no evidence of phase separation when chilled to -21 F. To confirm the flow-dependent evidence, it is recommended that rheological measurements be conducted with a greater variety of instruments. Also, further effort is necessary to identify a solution to hydrazine gas evolution phenomena with respect to bulk expansion and subsequent storability effects. Author
