When choosing the optimum operational modes of ERP in the composition of an engine installation it is necessary to take into account not only the mass of the propulsion system, but also the mass of the energy-plant. As the specific impulse of the traction increases, the mass of ERPS diminishes primarily at the expense of a decrease of the propulsive mass. The mass of the energy-plant increases, since with magnification of the velocity of the outflow of the propulsive mass energy expenditures for its acceleration increases as the square of the velocity. The optimum specific impulse of ERP is picked in such a way that the minimum magnitude of the aggregate mass of the power-plant is ensured. We propose the mathematical model for a choice of the optimum solution of operation of plasma drives in the composition of the mid-flight engine installation.
