This paper discusses the applications of thermal storage in spacecraft which are beneficial for weight savings. Tools are developed which allow a thermal system designer to perform preliminary thermal performance and weight trades on systems with thermal storage and those without. Thermal storage module designs which achieve high performance are also discussed. Analysis is performed to assess the impact of two heating profiles representative of typical spacecraft missions: a pulse power profile and the absolute value of a sinusoidal profile. The pulse power profile is typical of surveillance spacecraft dissipation and the sinusoidal profile represents solar heating. Using the tools developed in the paper, it was found that thermal storage can be valuable in reducing the system weight for pulsed heating with short pulse duration and for solar heating with short orbit periods.
