Application of the Interacting Laminar Shell Concept to Antennas and Other Ground Electronic System Support Structures

摘要

Interacting laminar shell construction is an arrangement of structural shells (laminar structural surfaces) permitting optimum utilization of high strength materials of exceptionally thin cross-section by inherent stabilization characteristics of the system. The range of applicability for the interacting laminar shell system of construction is for large spans and heavy loading. As applied to antenna structures, large steerable reflectors of excellent structural efficiency and, through the automatic curvature control system feature, of exceptional surface accuracy, may be constructed to function without radomes. This document provides the results of experimental stress analysis upon a model of an interacting laminar shell antenna structure, develops influence diagrams for design use, and gives preliminary designs for eight different antennas.
