Two new hypergolic systems have been discovered based on 3-amino-1,2,4-triazine as the fuel source. The compound was synthesized and found to be hypergolic with 100 nitric acid under ambient conditions and with solution of hydroxyl ammonium nitrate at elevated temperatures. Based on the exothermicity of these reactions, the material was selected as a candidate for further study as a possible base for a hybrid hypergolic system. The ignition delay of the nitric acid system and its predicted performance is discussed. The ignition temperature of the hydroxylamine nitrate system was determined through the use of differential scanning calorimetry at both a standard heating rate of 10 Cmin and a maximum heating rate of 40 Cmin.
