Abstract : NF prepolymer propellants were scaled up from laboratory batches (100 gms) to pilot plant size (70 lbs). A 1-pint completely remote facility was designed and built for the manufacture of experimental propellants on a 2-pound scale. Propellant for large motor evaluation programs was made in specially designed 1-gallon and 5-gallon facilities, using vertical planetary mixers, which eliminated personnel exposure at any time the propellant was being manipulated (mixing, casting, mandrel insertion, etc). An 80-lbm motor was successfully cast in this manner. Future plans call for extension of this technology to a 50-gallon mixer size.
