novel flexure design for small scale refelectarrays, specifically CubeSats, that requires high
level of deployment precision. Advantages of using a HSC flexure includes additional
thermal stability, lesser part count and passive deployment mechanism using the stored
strain energy. The proposed design is to use two flat HSC strips of thickness ℎ, length 2𝐿ℎ,
width 𝑊ℎ that attach to the core-reflector panel interface. The flexure satisfies two main …

This paper presents a novel flexure design for small scale refelectarrays, specifically
CubeSats, that requires high level of deployment precision. Advantages of using a HSC
flexure includes additional thermal stability, lesser part count and passive deployment
mechanism using the stored strain energy. The proposed design is to use two flat HSC strips
of thickness ℎ, length 2𝐿ℎ, width 𝑊ℎ that attach to the core-reflector panel interface. The
flexure satisfies two main requirements: ability to fold to a specific compaction 𝑑 without …
