PROGRAM ROE (REFLECTOR ORBITAL EXPERIMENT). PART II. PRELIMINARY DESIGN: UNFURLABLE METAL PETAL SOLAR REFLECTOR CONCEPT.
LOCKHEED MISSILES AND SPACE CO SUNNYVALE CALIF
A preliminary design study was conducted on the implementation of an all-metal solar reflector for an orbiting satellite experiment. The study included system and component preliminary design, certain aspects of vehicle integration design, ground feasibility testing, and the fabrication of critical or unproven components. Design and development of a ten-foot-diameter, unfurlable, metal-petal solar reflector was underway when the program was redirected to investigate the potential of developing a full-scale solar reflector. A limited program for developing techniques for the fabrication of large 40to 60-foot diameter, unfurlable, solar-dynamic reflectors, comprised of electroformed, monocoque, nickel petals is described. Designs and parts from the original project to develop a small 10-foot diameter, unfurlable, metalpetal collector were used to complete a machine for 1 applying plastic overlays 2 fabricating petals and backing mandrels 3 parting petals and 4 applying reflective and protective coatings. The resulting reflectivity, geometrical accuracy, and specific weights were tested and correlated with four different petal designs, fabricated by the various improved techniques. Author
