The invention discloses a two-dimensional driving fan-shaped solar wing capable of being repeatedly unfolded and folded. The two-dimensional driving fan-shaped solar wing comprises a two-dimensional driving mechanism, a pressing and releasing device, a solar wing restraining mechanism, a flexible wing surface, a wing surface repeated unfolding and folding mechanism, a fixed box plate, a movable box plate and a box plate restraining mechanism. The two-dimensional driving mechanism is connected with the fixed box plate, the pressing and releasing device is connected with the spacecraft body, the fixed box plate and the moving box plate, the solar wing restraining mechanism is connected with the spacecraft, the flexible wing surface is connected with the wing surface repeated unfolding and folding mechanism, the fixed box plate and the moving box plate, and the wing surface repeated unfolding and folding mechanism is fixedly connected with the fixed box plate and the moving box plate. The flexible airfoil folding and unfolding mechanism has the advantages that the flexible airfoil folding and unfolding mechanism can rotate in two dimensions and can be repeatedly folded and pressed on a spacecraft body, the flexible airfoil folding and unfolding mechanism is small in folding envelope, large in folding and unfolding ratio and light in weight, and the flexible airfoil folding and unfolding mechanism can be used for folding and unfolding the flexible airfoil together with the flexible airfoil folding and unfolding mechanism. Repeated unfolding and folding of the fan-shaped solar wing can be reliably achieved.
