Space based rotating film solar battery array

A self-rotating deployed film solar battery array, comprising:

• a plurality of film solar batteries;
• a plurality of electrical cables;
• a center axle positioned at a center of the array;
• and
• a plurality of connecting lines,
• wherein:
• the plurality of film solar batteries radiate to form a circle or a polygon array;
• each two adjacent film solar batteries being linked by connecting lines, each film solar battery being linked to the center axle by electrical cables;
• the plurality of film solar batteries being deployed and maintained in an array shape by centrifugal force in space;
• the film solar batteries are coiled on an outer surface of the center axle before deployment thereof;
• and
• the film solar battery array is used in spacecraft,
• wherein:
• each film solar battery array is shaped into a matrix of which a length-to-width ratio is greater than three, each film solar battery having an inside reinforcing rod positioned at a first end of the film solar battery adjacent the center axle and an outside reinforcing rod positioned at a second end of the film solar battery opposite the first end, an outer ring connecting line connecting ends of two adjacent outside reinforcing rods;
• an inner ring connecting line connecting two adjacent inside reinforcing rods at junctions M, N, respectively, each of junctions M, N being spaced away from a respective end of the corresponding inside reinforcing rod at a distance that equals to 25%-30% of a length of the corresponding inside reinforcing rod, each inner ring connecting line having a length equals to 50%-60% of the length of the corresponding inside reinforcing rods.
