摘要
A new experimental method combined with RTR techniques was developed to study the distribution pattern of particles in SRM nozzle during static firing test. The distribution pattern of simulated particles in test motor nozzle was studied by this method and some valuable results were obtained. The results show that particles are not uniform distribution when they pass through the nozzle. The further it is away from the axis of nozzle, the lower the particle concentration is. There are particles on whole cross section of nozzle divergent section and this fact shows that there is no `no particles zone' in nozzle divergent section. The results also show that the degree of particles diffusion is higher while the pressure in chamber is higher.
