Research of Methods Intensifying the Nitrous Oxide Decomposition in a Small-size Gas Generator with a Resonant Gasdynamic System for a Work-process Initiation

Small-size gas generators are used to create a high enthalpic flow and can be used in the power-plants of aerospace equipment. Nitrous oxide (N2O) is a promising monopropellant for a small-size gas generator. However, the use of a monopropellant requires the problem solution of its decomposition intensifying. The research is aimed at finding the ways to increase the degree of N2O decomposition in the resonant gasdynamic systems initiating a work-process and that are applied to the small-size gas generators. The paper presents: a mathematical model; the research results of the gasdynamic flow picture with the account of chemical reactions; as well as a comparative analysis of methods for the monopropellant decomposition intensifying. The above methods are based on the use of catalyst units to increase the efficiency of N2O decomposition in the resonant gasdynamic system and can be applied to the small-size gas generators of various applications.
