Fast-Running Physics-Based Models for Intercept Debris Aero-heating and Aero-thermal Demise

Accurate prediction of aero-thermal demise of post-intercept debris is a high priority for the United States Missile Defense Agency (MDA). Predictive tools for assessing the aero-thermal demise of intercept debris are needed to support BMDS effectiveness evaluations, flight test and range safety operations, and consequence mitigation assessments. During this Phase I effort, Shearwater Technology, Inc. will team with ITT Exelis to develop a fast-running simulation tool for predicting aero-heating and aero-thermal demise of post intercept debris with complex geometries. We have developed a novel approach to create a unique toolset that will have the capability to predict in-depth phenomena, such as ablation and surface recession, for three dimensional debris objects in high velocity flows. We also intend to benchmark the technology against existing test data and develop necessary criteria for scoring demise modes, such as consumption, catastrophic burn-through, dynamic pressure overload, and g-load crushing.
