Abstract
THERE IS A MILITARY REQUIREMENT FOR LIGHTWEIGHT RAPID DEPLOYABLE, EASILY TRANSPORTABLE, AND RUGGED UNGUYED TOWERS FOR C3 SYSTEMS. FOR LOS MM RADIO SYSTEMS, WIND INDUCED ANGULAR DEFLECTIONS AT THE TOP ARE SEVERELY RESTRICTED BY PRECISION SIGHTING REQUIREMENTS. A FUNDAMENTAL ANALYSIS OF STRESS REQUIREMENTS INDICATES THAT WEIGHT IS PROPORTIONAL TO MATERIAL DENSITY AND THE FOURTH POWER OF THE HEIGHT, AND INVERSELY PROPORTIONAL TO MATERIAL ELASTIC MODULUS AND CROSS SECTION WIDTH. THIS INDICATES THAT GRAPHITE IS THE OPTIMAL MATERIAL AND THAT STABILIZATION OF THIN WALL STRUCTURE AND REDUCTION OF TOWER WIND DRAG ARE CRITICAL ITEMS. A LIGHTWEIGHT UNGUYED COMPOSITE TOWER OF LOW DRAG AND HIGH RIGIDITY IS PROPOSED. USING STABILIZED GRAPHITE COMPOSITE STRUCTURE, A 100 FT COLLAPSIBLE TOWER IN THE 200LB WEIGHT RANGE CAN BE FABRICATED. A NUMBER OF INNOVATIVE CROSS SECTIONS, STABILIZING TECHNIQUES AND FOLDING MECHANISMS ARE PROPOSED. THE FOUR TASKS ARE DEFINED TO BE 1) IDENTIFY DESIGN PARAMETERS, 2) PERFORM A CONFIGURATION TRADE-OFF STUDY, 3) A STRUCTURAL ANALYSIS, AND 4) DRAFT DETAILED MECHANICAL DESIGN DRAWINGS.
