Combustion of NaN_3 Based Energetic Pyrolants

摘要

Burning rate of the pyrolants composed of NaN3 and metal oxides was invest igated in order to gain information on their combustion characteristics. The metal oxides mixed with NaN3 were Fe203, Co0, Co304, and Cu0. In addition, the effect of the addition of wiskers and fibers were also examined. The test results indicated that the burning rate was very dependent on the type of ingredients and the mixture ratio of the ingredients. The pyrolant composed of NaN3/CuO = 61/39 was appeared to be the highest burning rate, 50 mm/s at 7 MPa, throughout the burning rate experiments. The residue of the combustion products of each sample was examined to evaluate the effectiveness of the gas generation rate.
