To meet the requirements for the next generation of space missions, a paradigm shift is required from
current structures that are static, heavy and stiff, toward innovative structures that are adaptive, lightweight,
versatile, and intelligent. A novel morphing structure, the thermally actuated anisogrid morphing boom, can be used
to meet the design requirements by making the primary structure actively adapt to the on-orbit environment. The
anisogrid structure is able to achieve high precision morphing control through the intelligent application of thermal
gradients. This active primary structure improves structural and thermal stability performance, reduces mass, and
enables new mission architectures. This effort attempts to address limits to the author's previous work by
incorporating the impact of thermal coupling that was initially neglected. This paper introduces a thermally isolated
version of the thermal morphing anisogrid structure in order to address the thermal losses between active members.
To evaluate the isolation design the stiffness and thermal conductivity of these isolating interfaces need to be
addressed. This paper investigates the performance of the thermal morphing system under a variety of structural and
thermal isolation interface properties.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
