The invention relates to the field of satellite energy subsystems, and provides a winding type modular flexible solar wing substrate and a preparation technology thereof.The winding type modular flexible solar wing substrate comprises a flexible circuit board module, a fiber grid panel, a hanging connector and a foam board; the flexible circuit board module is adhered to one surface of the fiber grid panel, the foam board is adhered to the other surface of the fiber grid panel and extends along the length direction of the fiber grid panel, and the plurality of hanging interfaces are adhered to two sides of the width direction of the fiber grid panel. The bending radius of the base plate can be smaller than 50 mm, the buffer effect can be achieved in the folded state, mechanical damage to the battery piece caused by vibration in the satellite launching stage is weakened, and the base plate has the advantages of being high in flexibility, small in thickness, large in size, excellent in mechanical property and resistant to cold and hot temperature impact.

The application belongs to the technical field of solar sail and is specifically a heat-driven liquid crystal solar sail unfolding device. The liquid crystal solar sail unfolding device is composed of liquid crystal elastomers as a framework adhered to a solar sail film. The shape of the solar sail film includes a large equilateral triangle and three small squares outside the equilateral triangle, and each square film is symmetrically arranged with the triangular film. The liquid crystal elastomer is in the shape of a strip and is a double-layer film structure printed by a direct writing 3D printer. The bottom layer is horizontally printed, and the upper layer is vertically printed. When the temperature changes, the thermal expansion coefficients of the double-layer film are different, and the overall produces bending deformation. The application can achieve graded regulation of the unfolding degree by different temperatures to meet different requirements. Under the premise of realizing the intelligent storage and unfolding functions, the application has a high storage ratio. The structure is flexible and controllable, and the unfolding and contraction of a certain sail surface can be controlled to adjust the overall attitude and forward direction.

The application provides a high-utilization large-aperture optical mirror unfolding device, which comprises an inner mirror, an outer mirror, a hinge mechanism and a supporting rod, the inner mirror and the outer mirror are connected through the supporting rod; the outer mirror comprises a plurality of sub-lenses, any two adjacent sub-lenses are connected through the hinge mechanism; the outer mirror comprises a folding state and an unfolding state, the hinge mechanism is further used for switching the outer mirror between the folding state and the unfolding state; when the outer mirror is in the folding state, the outer mirror is located below the inner mirror; when the outer mirror is in the unfolding state, the plurality of sub-lenses are uniformly distributed in a circumferential direction along the outer side of the inner mirror. The inner mirror and the outer mirror are used in cooperation, the hinge mechanism is used for switching the outer mirror between the folding state and the unfolding state, the supporting rod is used for rigidly connecting the inner mirror and the outer mirror, which is helpful to improve the reliability of the whole device, through reasonable space layout, the synchronous, controllable and orderly unfolding of the inner and outer mirrors in orbit is realized, which is helpful to improve the space utilization and the storage ratio.
