Development of techniques for forming segments of a parabolic solar concentrator
This report covers a comprehensive research study of Androforming, explosive forming, and stretch forming as applied to shaping a parabolic reflector segment for use in a solar furnace. Development efforts were directed toward attaining accurate part contour, and assurance of process reproducibility. The three forming processes mentioned above were investigated by qualified contractors. Three test segments formed by each method along with a detailed analysis were submitted to MSFC. It was concluded that optimum results could be obtained with the stretch forming process. The three test segments of the solar concentrator tha.t were produced by this method, and evaluated optically, revealed a maximum contour deviation of O. 76 degrees.
