Title: Modeling of solid fuel gasification in combined charge of low-temperature gas generator for high-speed ramjet engine
Abstract: A novel mathematical model and a numerical method for studying the gasification of solid fuel in a combined charge of a low-temperature gas generator for high-speed flying vehicle with a sequential arrangement of a propellant and a fuel for generation of hydrocarbon gases are proposed. This scheme assumes the organization of cooling of the ramjet engine by means of a convective flow of gasification products of evaporable solid fuel. The calculations of the operating regimes of the gas generator with the characteristics of solid fuel as in polymethylmethacrylate are carried out. The operating time of ramjet engine of high-speed flying vehicle is estimated. It is shown that the operating time of the ramjet engine with a low-temperature gas generator increases with a decrease in the temperature of the gaseous combustion products of the propellant, the coefficient of interphase heat transfer, the fuel permeability coefficient and the inlet pressure in the gas generator.
