RESEARCH ON OPERATIONAL SLURRY FUELS.
Abstract
Two boron slurries were developed under this program to meet the Air Force operational criteria for use in a low altitude, supersonic ramjet propulsion system. One of these slurries contains a solids (boron) loading of 73 per cent, and the other contains 76 per cent boron by weight. Both were compounded with 2,2,5-trimethylhexane (TMH) carrier, Arlacel-83 wetting agent, and the AlMB-2 experimental gellant of Shell Development Corporation. Viscosity determinations of these slurries at 70 F showed that the 73 per cent boron slurry (TSAR-2.00) had a viscosity of 5 poise. The viscosity of the 76 per cent by weight boron slurry (TSAR-1.75-76) at the same conditions were 10 poise. Viscosity values for these slurries at -65F were 175 poise (73 per cent boron slurry-TSAR-2.00) and 330 poise (76 per cent boron slurry-TSAR-1.75-76). Both of these slurries show excellent room temperature storage properties, no degradation of physical properties under thermal cycling conditions, no gas formation, and good dynamic stability. The combustion efficiencies of both of these slurries were between 65 and 70 per cent at Mach 2.5 sea level, cold day at a fuel-to-air ratio of 0.024 as determined on the ARC 3.5-inch Micro-Ramjet Engine. These efficiencies are very similar to those obtained on this engine for previous 'work-horse'-type slurry formulations.
