ABSTRACT

This chapter describes the proof-of-concept demonstration of the CHEM structure technology. The objective was to build small structural models, demonstrate the basics of the CHEM processing cycle, perform simple analyses and validate this technology for some potential space applications. Most of investigated potential space applications were developed up to the TRL (Technology Readiness Level) 3; that is: simple analytical and experimental proof-of-concepts were demonstrated in the laboratory. In the course of CHEM technology development, all evaluation and test results were very encouraging. Moreover, all structural models demonstrated the basics of the CHEM structure concept.

The chapter describes the CHEM Technology Development Program that was established at Jet Propulsion Laboratory (JPL). The main objective was to develop and demonstrate a new, innovative end-to-end CHEM process for designing, fabricating, stowing, deploying and rigidizing space structures. It was aimed to develop and demonstrate the feasibility of all steps of the CHEM process. The program activities involved the design and fabrication of subscale CHEM structures and demonstration of the proof-of-CHEM concept. Their goals were to develop and validate a new CHEM self-deployable structure technology for selected space applications. It comprised of the development and testing of SMP foams, feasibility studies and selection of most promising applications.
