As integrated rigid\u2013flexible structures, flexible solar arrays face risks of repeatable stowing\/deployment function failure due to the nonlinear force-heat coupling effects. This paper takes symmetry as the core design concept, and through the introduction of rotationally symmetric sector layout, material stacking, and the stowing\/deployment mechanism, the thermal response of flexible solar arrays under extreme thermal environments was systematically investigated, which significantly improves thermal distribution uniformity of the flexible solar arrays and provides a new way of solving the problem of repeatable stowing\/deployment of flexible solar arrays. Furthermore, we propose a high- and low-temperature unfolding test method for fan-shaped flexible solar arrays, which verifies the reliability of symmetric fan-shaped arrays in high and low temperatures during the working process of repeatable stowing\/deployment and the safety of the stowing\/deployment process, as well as providing a reference for the subsequent design and test of flexible solar arrays of other configurations.<\/jats:p>","DOI":"10.3390\/sym17060822","type":"journal-article","created":{"date-parts":[[2025,5,25]],"date-time":"2025-05-25T20:39:36Z","timestamp":1748205576000},"page":"822","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Symmetrical Configuration Design and Experimental Study of a Repeatable Stowing Deployment Flexible Solar Array"],"prefix":"10.3390","volume":"17","author":[{"given":"Lei","family":"Cheng","sequence":"first","affiliation":[{"name":"National Key Laboratory of Aerospace Mechanism, Shanghai 201108, China"},{"name":"Shanghai Institute of Aerospace System Engineering, Shanghai 201108, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aoxiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Mechanism, Shanghai 201108, China"},{"name":"Shanghai Institute of Aerospace System Engineering, Shanghai 201108, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qifeng","family":"Cui","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Mechanism, Shanghai 201108, China"},{"name":"Shanghai Institute of Aerospace System Engineering, Shanghai 201108, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Desheng","family":"Wan","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Mechanism, Shanghai 201108, China"},{"name":"Shanghai Institute of Aerospace System Engineering, Shanghai 201108, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhexiao","family":"Ye","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Aerospace Mechanism, Shanghai 201108, China"},{"name":"Shanghai Institute of Aerospace System Engineering, Shanghai 201108, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Yue","sequence":"additional","affiliation":[{"name":"China Shanghai Aerospace Equipment Manufacturer, Shanghai 200245, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,25]]},"reference":[{"key":"ref_1","first-page":"1810","article-title":"Development and Trend of Spacial Flexible Solar Array","volume":"44","author":"Yang","year":"2023","journal-title":"Yuhang Xuebao"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Hoang, B., White, S., Spence, B., and Kiefer, S.
