摘要

A computational tool was developed that provides rapidly optimized component distributions over multisided structures, each with unique environmental loading. Computational requirements are small; on average, approximately 12 s was required using a 2.5 GHz dual-core computer for 54 components over a six-sided structure. Optimized, even, and worst-case distributions for 36 components in a hot-case orbit were found for total power of 100 up to 1200 W. On average, optimized component distributions reduced maximum temperatures by 5.4 K, increased minimum temperatures by 7.1 K,and reduced maximum temperature differences by 12.6 K over evenly distributed components. The largest and smallest maximum temperature difference reductions were 17.8 K at 400 Wand 9.5 K at 100 W, respectively.
