This paper describes a two-phase heat transfer based architecture for satellites that need to be conceived, configured, launched, and brought on-line very quickly. The architecture has been given the acronym SMARTS for Satellite Modular and Reconfigurable Thermal System. The SMARTS philosophy involves four simple design rules: (1) modest radiator oversizing; (2) maximum external insulation; (3) internal isothermalization; and (4) radiator heat flow modulation. For a typical multi-paneled satellite design, the paper will describe a SMARTS thermal control system that uses: (a) panel-to-panel conduction; (b) embedded heat pipe isothermalization; (c) radiator heat flow modulation via a TEC-controlled LHP; and (d) maximum external MLI. Analytical design trades are presented that compare the traditional "cold-biasing plus heater power" satellite passive thermal design approach to the SMARTS approach. The ultimate goal is to incorporate SMARTS into the design of future satellites envisioned by the Operationally Responsive Space (ORS) initiative. |
