The burning rate of pyrolants composed of NaN 3 and metal oxides was investigated in order to gain information on their combustion characteristics. The metal oxides mixed with NaN 3 were Fe 2 O 3 , CoO, Co 3 O 4 , and CuO. The effect of the addition of whiskers and fibers was also examined. The test results indicated that the burning rate was highly dependent on the type of ingredients and the mixture ratio of the ingredients. The pyrolant composed of NaN 3 /CuO (61/39) appeared with 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.
