Modeling Effort of TriTruss Modular Structure for In-Space Assembled Telescope Foundational Structure

Abstract

View Video Presentation: https://doi.org/10.2514/6.2022-0844.vid The TriTruss is a novel and innovative structural module developed by researchers at the NASA Langley Research Center to construct modular structures which can be assembled on-orbit for future persistent missions, including in-space assembled telescopes (iSAT) and platforms for science and communications. The TriTruss offers unique modular structural features including compact packaging for launch, the possibility of staged packaging, simple robotic deployment and assembly, and design versatility for specific space mission applications. This paper presents the modeling and analysis procedure for the TriTruss modular structure and the predicted frequency response of an iSAT primary reflector truss structure.
