Abstract

The goal of this paper is to come up with a THERMAL CONTROL SYSTEM for a small at ellite loctated in low earth orbit. For a satellite to operate properly in orbit, all components must work within their specific temperature limits. To keep the satellite and its components within their prescribed temperature ranges, a set of passive thermal control is selected and then two different design tools are utilized. First, a finite difference method (lumped parameter method) is utilized. In LUMPED PARAMETER METHOD, thermal network for heat interacting nodes are drawn and afinite difference based code is utilized to solve the set of non-linear algebraic equations. Then, afinite element based software (NISA II) is used to model the identical satellite and then compare the result. In general, in formulation of governing equations, because of low air density in low earth orbit (LEO), convection mode of heat transfer is neglected. Also, in orbit, the external surfaces of satellite receive direct solar flux, earth reflected solar flux (Albedo), and earth-emitted radiation while some of the subsystems dissipate heat. Results show a -4°C to 11.4°C temperature variation for internal devices and a -56.2°C to 69.4°C variation for external surfaces. Temperature obtained by both methods show very good agreement exceptfor the battery which is due to material used in battery modeling.
