Abstract
Abstract A plurality of arrays of solar cells are symmetrically stored about a spacecraft during launch to provide symmetrical loading. When the spacecraft is in operational configuration, the solar arrays are deployed adjacent each other on one side of the spacecraft to effectively form a single array and the single array may be oriented to face the sun by a common drive mechanism.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
232 words
In a spacecraft, first and second plane solar arrays symmetrically stored on the spacecraft and lying in two planes during a stored position of said arrays, first and second elongated link arms, each arm coupled at one end to said spacecraft and each arm coupled at the other end to one of said arrays, each said arm having a storage first position and a second position in which the two arms are adjacent to one another and side-by-side, the two arms lying in a common plane in both said first and second positions, said arrays, when in said stored position, being at an angle to said common plane, and each array being coupled to one of said link arms in such a way that each said array can be driven from said stored position to a position in said common plane, means for rotating said arrays with respect to said link arms to move said arrays from said stored position to said position in said common plane, and means for rotating said arms from said first position to said second position to thereby rotate both arrays to said position in which said arrays are in said common plane and in which an edge of one array is adjacent to a corresponding edge of the other array so that the two arrays can operate as a single array asymmetrically positioned on the spacecraft.
Claim 2
Dependent Claim
232 words
In a spacecraft, first and second plane solar arrays symmetrically stored on the spacecraft and lying in two planes during a stored position of said arrays, first and second elongated link arms, each arm coupled at one end to said spacecraft and each arm coupled at the other end to one of said arrays, each said arm having a storage first position and a second position in which the two arms are adjacent to one another and side-by-side, the two arms lying in a common plane in both said first and second positions, said arrays, when in said stored position, being at an angle to said common plane, and each array being coupled to one of said link arms in such a way that each said array can be driven from said stored position to a position in said common plane, means for rotating said arrays with respect to said link arms to move said arrays from said stored position to said position in said common plane, and means for rotating said arms from said first position to said second position to thereby rotate both arrays to said position in which said arrays are in said common plane and in which an edge of one array is adjacent to a corresponding edge of the other array so that the two arrays can operate as a single array asymmetrically positioned on the spacecraft.
Claim 3
Dependent Claim
57 words
In the spacecraft of claim 1 further including drive means fixed to the spacecraft in a position intermediate said arrays, when the arrays are in said stored position, said drive means being coupled to said one end of each said arm and being capable of driving said arrays when said arrays are deployed from said stored position.
