Abstract:

Three 5000-g batches of propellant N-1825 were prepared with varying percentages of ammonium perchlorate oxidizer and guanidine picrate coolant. Tests were made to determine 1 whether or not the time-to-peak pressure of propellant N-1825 could be reduced to a value similar to that of N-5 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 N-1825 can be processed and the mixing problems can be overcome. Tests on the commercially available propellant, C-501, showed that 1 it exhibits little tendency toward decomposition when subjected to 300F for 168 hr 2 it is comparable to N-1825 with respect to percentage variation from the mean peak pressure and time-to-peak pressure and 3 the percentage of acidic gases from this propellant is approximately twice that of N-1825. Testing of delay-sealed matches showed that the present design gives consistent elay-time results. Author
