Abstract: A self rotating deployed film solar battery array includes film solar batteries, electrical cables, a center axle and connecting lines. A plurality of long strip shaped film solar batteries radiate to form a circle or a polygon-array. Two adjacent film solar batteries are linked by connecting lines. Each film solar battery is linked to the center axle by electrical cables. The film solar batteries are deployed and maintained in an array shape by a self rotating centrifugal force in space. The film solar batteries are coiling outside the surface of the center axle before their deployment. The unit weight of a thin film battery is only 1/30 of a traditional solar cell paddle.

Abstract: A self rotating deployed film solar batteries array is composed of film solar batteries, electrical cables, a center axle and connecting lines: many long strip shaped film solar batteries radiate to form a circle or a polygon-array, when linking two adjacent film solar batteries with connecting lines, each film solar battery links to a center axle with electrical cables; film batteries deployed and maintained in an array shape by self rotating centrifugal force in space; film batteries are coiling outside the surface of a center axle before their deployment. The unite weight of thin film battery is only 1/30 of traditional solar cell paddle. The film solar batteries array can be used in various satellite, space station and solar power rocket. It will greatly reduce the launching cost, enhance the power for spacecrafts and double the length of service life.

Abstract: The spin-stabilized film mirror consists of reflecting film, cables, and the weights and load connected therewith. The film mirror surface is a curved face of revolution. The edge of the film is connected by cables to multiple weights at the periphery of the mirror face, and the weights in turn is connected to the load, which is located at the position of mirror axis. The film mirror stretches out in space and maintains its prefabricated form of curved face of revolution by spin centrifugal pull. The mass of the film mirror is less than 40 g per square meter, capable of doubling and redoubling the generating power of solar energy equipment on a spacecraft, reducing significantly the weight of the system. Film mirrors of large scale is capable of collecting solar energy of tens of square kilometers in space, paving the way for large space solar power station.
