摘要

One of the best ways to improve the thermodynamic performance of a gas-turbine plant (GTP) is to introduce into the cycle multistep compression and expansion processes with intermediate cooling of the working body between the compressor steps and heating of the working body between the turbine steps. Even though the structure of the plant becomes more complicated, the adoption of multistep processes could reduce the mass and size of the GTP by reducing the flow rate of the working body circulating in the plant's loop and increase the thermal efficiency of the cycle. Without going into the technical aspects of the development of such plants, we shall examine the effect of additional compression and expansion steps on the efficiency and specific surface area of the radiative cooler of a space NPP.
