The deployment and curing of multi-layer film structures for inflatable and large Gossamer-type space structures requires accurate modeling of the temperature distributions within and among the different layers of the structure. The Sinda Temperature Translator (STT) was developed to specifically provide the application of accurate thermal load profiles on each component of thin film multi-layer space inflatable structures during the performance of multidiscipline analyses. STT provides a methodology to accurately map the temperatures obtained during transient thermal orbital analyses (finite difference methods) to structural finite element analyses (FEA) models. The derivation of the equations are for the translation of temperatures from the thermal models such as SINDA/G, which places the temperatures at the centroid of the elements, to traditional structural models, such as Cosmos/M and NASTRAN that places the temperatures at the corners of the element.
