Atomic-6 Light Wing is a novel lightweight, high specific stiffness, and redeployable solar array structure.

​

The structure includes one or more Atomic-6 Space Mast, a shape memory mast with double omega (closed and non-slitted) cross section. The mast is deployed from the yoke at the root of the array. As the Space Mast deploys, Atomic-6 Solar Backsheets are suspended above the mast and pulled out. The Solar Backsheet is a directionally stiffened substrate that can be populated with any type of solar cell. Solar Backsheets can support rollable or Z-fold configurations. The Solar Backsheets are connected in series from the tip of the mast to the root by Atomic-6 Space Hinges, a shape memory hinge that runs along the width of the blanket providing intrinsic lateral stiffness. Once deployed, the Space Mast tensions the Space Hinges and Solar Backsheets to achieve high axial stiffness at low mass. The root mounted deployer minimizes the cantilevered mass to minimize the modal frequency of the array. During retraction, the Space Hinge ensures uni-stable directional behavior and assured separation of solar panels for a reliable retraction and redeployment.

​

• Space Mast rollout mast is lighter and more reliable than hinged systems

• Space Hinge shape memory, directionally stiff hinge enables redeployment of Z-fold and lateral stiffness of the solar panels. With no moving parts to bind or fail, reliability is maximized.

• Solar Backsheet super thin and optionally stiff to minimize solar panel mass for any type of solar cell
