Abstract: In this paper the combustion catalysis of nitrocelluloes-lead (NCPb) on the double base propellants (DBP) in pressure range from 2MPa to 30MPa was studied by using "drum-turning photograph" method to measure the burning rate of DBP which contain various quantity of NCPb. It is shown that NCPb makes DBP produce the superrate effect at lower pressure and the plateau combustion effect near 10MPa, and the pressure exponent of burning rate reduces down to 0.0801 in plateau zone. It is also found that the higher combustion speed and the lower pressure exponent in plateau zone are obtained with the increasing content of NCPb used as catalyst in DBP;and that under a constant lead content in DBPs, the NCPb containing about 10 percent of lead has the best plateau combustion catalysis.
