Description
Summary:To address the challenges associated with existing space solar power station (SSPS) concepts, including noncompact structural design, nonuniform solar energy flow density, and orbital deployment complexities, an integrated, highly modular, flat functional structure based on the Miura origami pattern is proposed. The flat functional structure consists of a flat quadrilateral Fresnel concentrator for solar energy collection, a photovoltaic array for photoelectric conversion, and a transmitting array for microwave power transmission. To optimize space utilization and enhance the deployment ratio, the Miura origami pattern is introduced, and the subarray composed of multiple flat functional structures can be packaged in a payload capsule before launch and unfold as a standard rectangle with uniform thickness and a flat surface in orbit, improving the transportability of the launch vehicle. Additionally, to solve the nonuniform solar energy flow density, a Fresnel concentrator was employed to achieve uniform irradiation, while the transmitting array was designed to achieve good electrical performance. Finally, the structural parameters and efficiency of the SSPS system composed of multiple subarrays are presented in detail.
