Abstract

Satellite THERMAL CONTROL subsystem has the responsibility of maintaining the temperature of othersubsystems in an allowable range. The purpose of this paper is to design an optimal THERMAL CONTROLsubsystem of a SATELLITE. In order to achieve this goal, at first a software was developed and validated forsatellite thermal analysis. Receiving orbital data and SATELLITE’s properties, the software simulates theposition of the SATELLITE in any desired orbit and calculates the input and output thermal flux. Meanwhile, the temperature of each side of the SATELLITE is calculated in cold and hot cases. Finally, it calculates theminimum and maximum temperatures of the SATELLITE. A combination of three commonly used thermalcontrol methods in small SATELLITEs was used. Insulation thickness, thickness of radiator cover, and thepower of heater are considered as design parameters and allowable temperatures of surfaces (minimumand maximum allowable temperatures) are considered as design constraints. A weighted function ofmass, cost, and power consumption of THERMAL CONTROL system are chosen as objective function whichc an be representative of the cost. Sequential Quadratic Programming as a powerful method in nonlinearoptimization was used to optimize THERMAL CONTROL properties. The results demonstrated that theobjective function improved dramatically compared to the initial design. High speed, appropriateprecision, and extensibility of this software in THERMAL CONTROL subsystem design of a vast majority ofsmall SATELLITEs, makes this research valuable. Therefore, this software could be integrated as the thermalcontrol subsystem design module with multidisciplinary DESIGN OPTIMIZATION of SATELLITEs.
