Differential Model and Evaluation of the Formal Kinetic Law in the Analysis of Combustion in a Solid-Propellant Gas Generator

Abstract

This paper presents an approach to the generalization of the features of solid propellant combustion in gas generators of propulsion systems based on a one-dimensional differential model. The heat release rate function represented by mutually orthogonal Laguerre polynomials in the differential model is identified by solving the inverse problem of combustion theory and using measured gas parameters in the gas generator. This makes it possible to establish the relationship between the solid propellant combustion features and the gas generator operating modes and formulate boundary conditions for numerical investigation of the solid propellant gas generator.
