The next generation spacecraft thermal protection system (TPS) response modeling tool is under development at NASA Ames Research Center. This presentation will provide an overview of the features in the latest version of the solver.
Icarus is a 3D, unstructured, parallel, finite volume implementation of the material response equations. Traditionally, for spacecraft heatshield design, a one- dimensional solver (e.g. FIAT) is used. While 1D analysis is often sufficient for heatshield acreage where there is little curvature, it is less accurate near features, in regions of high curvature (e.g. shoulder regions), or for small ground-test coupons. Leveraging unstructured 3D grids allows for material response simulations on arbitrarily complex geometries. To this end, the most recent version of Icarus, v1.2, provides the user with several new features which will enable accurate solutions of fully integrated heatshields. In addition to a v1.2 overview, recent/ongoing developments will be discussed.
