A software package has been developed that allows calculating the parameters of multi-component gas flow in a rocket engine nozzle. The calculation algorithm is based on the solution of an augmented system of Euler equations for a multicomponent gas according to the of S.K. Godunov scheme. The Riemann problem is solved by the exact method of S.K. Godunov. Test calculations of flows of two-component non-reacting gas mixtures in a radius-conical nozzle were performed. The results of the test calculations are compared with the solutions obtained using one-component gas-dynamic equations.
