Abstract : Three 5000g batches of propellant N1825 were prepared with varying percentages of ammonium perchlorate oxidizer and guanidine picrate coolant. Tests were made to determine: (1) whether or not the timetopeak pressure of propellant N1825 could be reduced to a value similar to that of N5 by reducing the ave oxidizer particle size; and (2) the effect of varying the percentages of ammonium perchlorate and guanidine picrate. Erratic test results were obtained from the three batches. It was concluded, however, that propellant N1825 can be processed and the mixing problems can be overcome. Tests on the commercially available propellant, C501, showed that: (1) it exhibits little tendency toward decomposition when subjected to 300F for 168 hr; (2) it is comparable to N1825 with respect to percentage variation from the mean peak pressure and timetopeak pressure; and (3) the percentage of acidic gases from this propellant is approximately twice that of N1825. Testing of delaysealed matches showed that the present design gives consistent elaytime results. (Author)
