Analytical and Experimental Evaluation of Two Designs for a Graphite/ Epoxy Antenna Feed Truss for a Communications Satellite

Abstract

Two final candidate configurations for a communications satellite antenna feed truss are studied to determine which concept is better suited to the application. Both candidates are designed with graphite/epoxy tubing, and were screened from several other concepts in a preliminary study. The comparative assessment in the present study is based in part on cyclic thermal fatigue design development tests, and in part on dynamic response analyses and finite-element stress analyses.
