SPACECRAFT SOLAR BATTERY OF LARGE AREA Russian patent published in 2007 - IPC B64G1/44 B64G1/22 

FIELD: space power engineering; film-type solar batteries on base of amorphous silicon.

SUBSTANCE: proposed solar battery has central power member. Solar battery consists of two sections. Each section is formed from standard film-type trihedral prisms on base of inflatable tubular skeleton. Outer surface of this skeleton is coated with compound which gets hardened under action of ultraviolet and visible solar radiations. Solar battery deployment system includes two electric motors of central power member and additional electric motor. Inputs of these electric motors are connected with outputs of pitch, yaw and roll channels of solar battery control unit. Solar battery is additionally provided with additional position electric motors which are used for discrete turn of each trihedral film-type prism through angle of 0^o to 360^o at pitch of 120^o. Specification gives description of solar battery modification which includes reserve film-type panels increasing active life of solar battery. Total power of proposed solar battery is about 120 kW.

EFFECT: enhanced reliability of film-type panel tension.
