Aerospace Vehicle Signature Modeling Technologies

The proposed work will incorporate the newly released software into the signature analysis workflow. Extensions of the US3D flow solver will include improvements to the decoupled implicit solver to robustly and efficiently handle reacting flow. Trajectory specification, conjugate vehicle heating, and ablation with surface recession will be enabled through use of a Trajectory Ablation & Shape Change (TASC) solver. Finally, laminar-to-turbulent boundary layer transition prediction tools will be used to improve the accuracy of US3D simulations. The proposed enhancements will directly benefit aerospace vehicle signature prediction phenomenology by improving the accuracy and robustness of the underlying flowfields.Approved for Public Release | 17-MDA-9219 (31 May 17)
