一种空间超大型可展开柔性聚光器

We propose a new configuration for the large-scale lightweight high-precision deployable flexible concentrator considering the need for large-aperture concentrators by the Space Solar Power Station (SSPS). By theoretical modeling, computational simulation, and optimized design, we analyze the problems including the principles of the parabolic configuration, unfolding mechanism and stability of the deployable structure, and accuracy of dynamic focusing. We then complete the design for a largescale deployable compliant concentrator. A multi-layer elastic petal mirror composite structure based on the optimization design method is further proposed for the large-aperture compliant concentrator. Due to the use of a thin-plate and cable structure, the concentrator has the advantages of high accuracy, large volume ratio, light weight, and easy online control, providing an innovative design method for kilometer-scale concentrators used in the SSPS.
