Abstract
The working process in the regenerative gas generators of liquid rocket engines is analyzed and a method for computer simulation based on the Zel’dovich’s model of “quenching” the composition of the products of high-temperature combustion as a result of rapid cooling on supplying an excess of the low-temperature component and the resulting chemical quasi-nonequilibrium is developed. The method is implemented and tested on the basis of the TERRA software package in calculations of the composition and properties of the propellant produced by regenerative gas generators using oxygen as the oxidizer and methane as the fuel. The vacuum specific impulse of the considered fuel is calculated for the possible conditions of a quasi-nonequilibrium working process.
