A solar dynamic ground test demonstrator space power system is being developed. The system comprises a complete Brayton engine—a heat receiver, concentrator, radiator, recuperator, heat rejection gas cooler, and turboalternator compressor. All of these components will be operated inside a vacuum tank. The engine is powered by simulated sunlight from an external bank of lights. Successful completion of the testing will indicate the readiness of solar dynamic power for space applications. This paper discusses the thermal and structural analysis of the heat receiver component. The analysis performed indicates that all components comfortably meet the life and cold start requirements, while maintaining the necessary overall performance.
