Abstract

The article deals with the method and instrumentation for concentration measurement in the combustion-products condensed phase of the methane-oxygen gas generator. The measurement results of the soot particles concentration in different gas generator operating modes are presented. The measured soot concentration amounted from (2...14)-10-4 % that 2... 3 order less than equilibrium values.
