| Abstract: | Mathematic treatment of particle size distribution in solid propellant ispresented, and the particle size distribution of aluminium powder and combustionresidue of Al-containing propellant are taken as examples to be analysed by means ofcommonly used theoretical distribution functions,including normal distribution, log-normal and K-distribution, in statistic analysis of partical size data. On the basis ofCulick's damping model the effect of particle size distribution on instable combustion inrocket motors are evaluated and discussed. |
