Abstract

The efficiency of closed gas-turbine space-based plants is analyzed. The weight–size characteristics of closed gas-turbine plants are shown in many respects as determined by the refrigerator−radiator parameters. The scheme of closed gas-turbine plants with a gas-dynamic temperature-stratification device is proposed, and a calculation model is developed. This model shows that the cycle efficiency decreases by 2% in comparison with that of the closed gas-turbine plants operating by the traditional scheme with increasing temperature at the output from the refrigerator−radiator by 28 K and decreasing its area by 13.7%.
