摘要

Preliminary experiments have been performed with the aim to prepare and characterize propellants with ammonium dinitramide, A-D-N, as oxidizer and with the energetic polymer, glycidylazide polymer, GAP, as binder. Well-cured propellants could be prepared with the tri-functional isocyanate Desmodur N-100. The thermal stability of the propellants was good, yet the impact sensitivity was high. A propellant containing 47% A-D-N was strand burned with a burn rate of about 35 mm/s at 10 MP-a. The pressure exponent in the regions 0.9-2.4 MP-a and 5-18 MP-a was 0.99 and 0.67, respectively. Thermochemical calculations show that it is possible to make gun propellants with much higher performance than those used currently while, for rockets, the results show possibilities to make high performance propellants with low signature. Much work is still to be done. Desmodur N-100 self polymerizes on storage. Therefore it is important to find another A-D-N compatible curing system, which is more stable and better defined than Desmodur N-100.
