Title: Point-focus concentrator reflector assembly: Phase 1

Technical Report ·
DOI:https://doi.org/10.2172/5691864· OSTI ID:5691864

A point-focus concentrator reflective assembly was developed in Phase I on contract 21-3695 under the direction of Sandia National Laboratories, Albuquerque. This concentrator is conventonal in presentation, yet innovative in detail. The development concentrated on structural efficiency and production design to achieve a high performance at minimum cost. The concentrator design achievs stiffness and strength through the integration of two structural elements. The optical element provides the reflective surface accuracy; a secondary support structure provides resistance to uniform and non-uniform load conditions. A retractable receiver strut, which moves the power conversion assembly out of focus in emergency power loss, was also incorporated. This same assembly provides maintanance access to the engine near ground level. A full-scale optical element was fabricated. Slope error was measured at 1 mrad. Concentrator performance was projected to be 88%, optical. This point-focus concentrator reflector assembly design provides low weight, low cost, and simplicity. Our analysis indicates these benefits are gained without impairing performance. 7 refs., 44 figs., 10 tabs.
