Abstract : This report presents the results of an investigation on the weight characteristics of future spacecraft thermal management systems. The sensitivity of the thermal management system weight to the performance requirements of both evolutionary and revolutionary spacecraft missions has been studied. A numerical analysis modelling the transient heat flow through the thermal management system was performed. The performance parameters included the peak thermal load and the peak-to-average thermal load ratio. In addition the sensitivity of the thermal management system weight to the choice of phase change material for heat storage was determined via a heat of fusion parametric analysis. (Author)
