Abstract

A device was improved to collect the condensed particles of the solid propellant. The typical HTPB composite propellant containing 17% aluminum was experimentally investigated under different condition. Collection experiments and particle size analysis were performed so as to investigate the effects of operation pressure and concentration degree on particle size distribution. The experimental results show that the range of particle size is from 0.27µm up to about 100µm. The majority of particle size is from 0.27µm to 10µm. The result indicates that the particle size distribution is primarily dictated by the operation pressure. The particle size is reduced with increasing pressure, at the same time the diameter distribution is concentrated. It is found that the particle diameter is raised with the increase of the concentration degree.

Key words： solid rocket motor; combustion chamber; condensed particle; particle collection; size distribution
