SOLAR ARRAYS FOR "VICTOR" MICRO SATELLITE

Summary :
|
|
SUMMARY. MICROSATELLITE GENERAL REQUIREMENTS IMPLY THAT SOME SUBSYSTEMS OR PARTS SHOULD BE OBTAINED IN THE MARKET AND MUST BE SPECIALLY ADAPTED OR DEVELOPED.
THE DESIGN AND DEVELOPMENT OF THE µ SAT PANELS IS PRESENTED IN THIS PAPER.
PRELIMINARY POWER CONSUMPTION CALCULATIONS WERE PERFORMED IN ORDER TO HAVE A POWER REQUIREMENT. THERMAL CONTROL CALCULATION PROVIDES INFORMATION ABOUT SERVICE TEMPERATURE OF SOLAR CELLS. ENVIRONMENTAL REQUIREMENTS WERE COMPATIBILIZED AFTER AN EXTENSIVE STUDY OF AVAILABLE STANDARDS AND RELATED MICROSATELLITES LITERATURE.
SOLAR CELLS WERE OBTAINED IN THE MARKET AND AN INTENSIVE TEST PROGRAM WAS PERFORMED TO SIMULATE THERMAL , FATIGE, AND DEGRADATION . U.V. IRRADIATION DAMAGE WAS ALSO TESTED.
OPTICAL PROPERTIES WERE DETERMINED IN ORDER TO INCREASE CONFIDENCE IN THEORETICAL CALCULATIONS.
PEEL TEST OF CELLS BONDED TO ALUMINIUM PLATES WITH SILICONE RUBBER WERE USED TO DEFINE SURFACE FINISHING AND BOND LAYER THICKNESS.
ANOTHE PROTOTYPE PANEL WAS BUILT AND TESTED UNDER NOISE , VIBRATION AND SHOCK ENVIROMENT.
FINALLY TWO FLIGHT PANELS WERW BUILT AND TESTED FOR THE µ-SAT VICTOR SATELLITE AND CONTINUE WORKING SUCCESFULLY SINCE ITS LAUNCHING IN AUGUST 1996.-
THESE ACTIVITIES PROVIDE µSAT TECHNICAL STAFF A GOOD KNOWLEDGE IN SOLAR PANELS TECHNOLOGY, AND THE CONFIDENCE THAT THESE PARTS WILL WORK PROPERLY IN SPACE CONDITIONS
KEY WORDS: MICROSATELLITE, SOLAR PANELS, SOLAR CELLS
